SAR Buying Guide: ROVs for Underwater Retrieval - Deep Trekker

The Rise of ROVs in Search and Recovery Missions

Search and Recovery is the operation of finding and retrieving lost or missing persons, or the retrieval of valuable objects, such as police evidence or overboard vessel equipment. Undertaking such missions can involve a variety of methods and tools. Traditionally, those methods have included:

Methods such as bounce diving, which involves the diver going to depths up to 60 feet rapidly and repeatedly, oftentimes with as little as ten to fifteen minutes of bottom time, can be incredibly risky for divers. You don't know what that target is on the bottom. It could be a huge entanglement hazard for that diver.

In recent years, the use of ROVs (remotely operated vehicles) has significantly mitigated this risk by getting eyes underwater that are able to identify anomalies that have been located by sonar before sending a diver down into an unknown situation and potentially dangerous environment.

“When you start having to splash divers for multiple high interest points in the water, you're limited to how long the divers can stay on the bottom, to how much personnel you have on scene,” explains Shane Seagroves, Director of Emergency Services, Lee County, NC. “By introducing the ROV into that process, you're only limited to battery life.”

These search and recovery missions are typically conducted in emergency situations, such as boating accidents, missing persons, or lost cargo. Lost cargo can also be part of criminal investigations, where law enforcement may search for evidence or weapons that have been discarded or hidden. The goal of these missions is to locate and recover the object or person as quickly and safely as possible.

Search and Recovery missions can also be recreational activities such as commercial scuba diving, where divers may search for lost items or sunken artifacts.

When it comes to traditional methods, divers are most commonly used for search and recovery missions. However, ROVs are growing in popularity, and can either be used in place of divers, or as an additional tool to assist divers and help make their job safer. Each method comes with its own advantages and disadvantages, so let’s quickly break down each one.

The Role of Divers in Search and Recovery

One of the main advantages that divers have in search and recovery missions is the ability to physically search for and recover objects with their hands. Being able to see and feel the environment they are working in allows for more precise retrievals, and also makes navigation in tight or difficult areas such as complex structures easier since they can quickly adapt to the environment and adjust their search patterns accordingly. Also, being able to provide more accurate assessments of the situation is extremely valuable.

The disadvantage of using divers is the inherent risk involved with such dangerous and physically demanding tasks. Any time a diver is splashed, they run the risk of decompression sickness, hypothermia, physical exhaustion, or the danger of entanglement. They are also limited in the amount of time they can spend underwater, as well as the depths they are able to reach. Visibility can also be an issue in murky water where they have limited or zero visibility, which can be incredibly dangerous for the divers.

Harnessing the Power of ROVs in Search and Recovery

ROVs have proven to be incredibly useful tools for conducting underwater search and recovery operations. ROVs can be controlled from a surface vessel or remote location where operators can safely search deeper and more dangerous areas without putting divers at risk. They can also be equipped with a number of modular tools to assist in search and recovery missions, such as sonar, grabber claws, laser scanners and sensors that help locate and identify objects on the sea floor, and high-definition cameras that can detect and record information.

ROVs remove the risk of injury and can be deployed in situations where it may be too dangerous for divers to enter the water. They can also operate in low visibility water, or in poor weather conditions, and can cover large areas of water quickly, as well as maneuver in tight spaces and at depths that would be difficult or impossible for humans to reach.

Limerick Marine Search and Rescue Service (LMSRS) uses a Deep Trekker ROV to assist divers and improve safety in their operations. Their treasurer, Mal Sherlock explains, “We wouldn’t be entering a diver in water that has speeds of four knots, but we can enter this unit at four knots, that would be at its maximum speed. This will negate the chance of us putting a diver into the water to endanger themselves going into a dangerous area.”

However, ROVs are limited by battery life and could require multiple trips to the search and recovery location, and can occasionally have difficulty navigating through complex environments.

Combining Divers and ROVs for Optimal Results

Ultimately, the choice between divers and ROVs for search and recovery is highly dependent on the specific circumstances of the situation, and a combination of both is quite often the most effective approach in many cases. The strengths of each method can be leveraged to complement one another, leading to more efficient and successful outcomes.

For example, ROVs can be used to monitor divers while underwater, allowing topside support teams to have eyes on the divers and provide real-time guidance, while divers are able to perform delicate tasks and make on-the-spot decisions, leveraging their experience and expertise.

In high-risk situations, ROVs can be used to conduct preliminary assessments, identify potential dangers, or handle tasks in hazardous environments, minimizing the exposure of divers to dangerous conditions, and allowing them to perform their dives much faster and more efficiently. By utilizing ROVs for initial surveys, inspections, or simple tasks, divers can focus their efforts on more critical or complex activities, optimizing the use of resources and reducing overall costs.

Additionally, ROVs are equipped with advanced sensors, cameras, and sampling tools that can provide detailed visual data, collect samples, and perform measurements underwater. By combining the comprehensive data collection capabilities of ROVs with the situational awareness of divers, a more accurate understanding of the underwater environment can be obtained.

There are many advantages to combining both divers and ROVs in search and recovery missions, including training and skill development, efficiency, and cost-effectiveness. This integration allows for efficient utilization of resources, improved safety, enhanced data collection, and expanded operational capabilities. These are some of the many key points to consider, demonstrating how this synergy can lead to optimal results by leveraging the strengths of each approach.

“Hopefully it will change how we work and give us a better chance of recovery,” says Mr. Sherlock.

Key Considerations for Selecting the Ideal ROV for Your Search and Recovery Mission?

Defining the Mission Objectives

You’ll want to consider the specific goals of your mission, as well as the locations and environments you’ll be working in to determine what options you’ll want to prioritize when deciding which ROV is right for your needs.

What will you be using the ROV for? Are you searching for missing persons, lost equipment, shipwrecks, or using it for evidence recovery? Are you conducting the search in a small body of water, a large area, or a fast-moving, high-current river? These are the types of questions you’ll want to ask when making a purchase decision.

Mobility and Deployment Efficiency

The portability of ROVs is an important factor to consider in search and recovery missions. When time is so critical to the success of a mission, it’s important that the ROV is easy to transport and quick to deploy for it to be an effective tool in your search and recovery efforts.

Other things you might want to consider are a modular design that allows you to quickly add or remove components, and power options, such as lithium-ion batteries, that make the vehicle more portable without the need for heavy or bulky equipment that could slow down the process of retrieval.

Control and Maneuverability in Challenging Environments

Performing search and recovery missions in unpredictable marine environments can be dangerous and quite challenging. Even when using ROVs in turbid or high-current waters, it can be a challenge to pilot the vehicle and maneuver through the water.

ROVs with high-performance thrusters are essential for maintaining control and maneuverability in strong currents during search and recovery missions and can greatly improve the ease of retrieval by allowing for more precise controls. Utilizing stabilizing systems can also be invaluable, as well as GPS systems to help navigate and locate the ROV when visibility is low.

Factors Influencing ROV Selection

Assessing specific technical specifications of an ROV is crucial in selecting the most suitable option. Consider the following factors when evaluating ROVs for search and recovery missions:

Depth Rating

Evaluate the maximum depth rating of the ROV to ensure it can operate effectively in the intended search areas.

Tether Length

Consider the required length of the tether based on the depth and distance the ROV needs to cover during missions.

Payload Capacity

Assess the payload capacity of the ROV to determine if it can accommodate any necessary additional equipment or attachments.

Camera Quality

Look for ROVs equipped with high-quality cameras to capture clear images and videos for effective target identification and documentation.

Sonar Capabilities

Evaluate the sonar capabilities of the ROV, including imaging and positioning systems, to enhance visibility and target detection in murky or dark waters.

Power Options

Consider the available power options, such as battery types and capacity, to ensure sufficient operational time and endurance for the search and recovery missions.

This feature is invaluable in search and recovery missions, especially in difficult conditions or unfavorable weather.

One of the most valuable features for search and recovery missions is the rotating capability when adding an imaging sonar. With this modular add-on, you can adjust the angle to sweep targets and get precise viewing angles, and because of its stable design and vertical thrusters which enable lateral movements, the REVOLUTION provides excellent performance with USBL and Sonar.

Thanks to the quick-change battery system, it's also easy to perform on-the-spot field battery changes in under a minute.

Choosing the Ideal Deep Trekker ROV Package for SAR Missions

Which Deep Trekker ROV package is best for search and recovery missions is highly dependent on the circumstances of the mission, and more importantly, the location and environment in which the search and/or retrieval is being conducted.

In relatively still water with good visibility, the DTG3 is a great tool with superior portability and ultra-fast deployment capabilities that can make getting eyes underwater quickly an easy task. However, in more complex and challenging environments, the PIVOT and REVOLUTION ROVs would be better suited tools for the job.

Let’s take a look at two packages that would be best for most search and recovery missions:

PIVOT Expert with Blueprint M750D Sonar

The PIVOT Expert package includes the BRIDGE integrated controller, SD Card, and the ROV itself, equipped with the 220-degree rotating camera head, six precision thrusters, and LED floodlights to illuminate your targets. You will also receive two rugged Pelican carrying cases to house the entire system for enhanced portability.

The Expert package also comes with the 97-degree tilting tool platform, capable of housing a variety of add-ons, such as the Blueprint M750D sonar, and comes included with a grabber claw. Also included is a 150m fiber optics tether with options up to 850m, and a spare battery set for quick swaps to maintain power on extended missions.

The Blueprint M750D is a dual-frequency multibeam sonar that provides high-resolution imagery up to 120m, an integrated velocimeter for improved accuracy, and a peak operating frequency of 1.2MHz. The dual frequency capability makes the M750D excellent for both short and long-range operations for effective target identification in turbid waters.

In Search and Recovery operations, First responders looking for evidence or drowning victims typically use sonar to sweep an area to identify potential targets and investigate. Cameras and divers are often unable to effectively search due to poor visibility in underwater environments. Imaging sonar is an effective tool to identify the target since side scan data does not always produce an exact location, which makes navigating back to the potential target difficult. Once the target is identified, the sonar can be used to continue to track the target as you move closer, and when you get close enough, it can even be used to perform visual verification.

REVOLUTION NAV with Blueprint MD Multibeam Imaging Sonar

The REVOLUTION NAV package includes the BRIDGE integrated controller, SD Card, and comes equipped with the 260-degree rotating camera head and grabber, LED floodlights, extended length fiber optics tether with options up to 850m, and a 10cm laser scaler for accurate estimations of object sizes. Like the PIVOT, two rugged pelican carrying cases are included to house the whole system, providing excellent portability for the REVOLUTION RAV package.

The package also includes a battery set as well as a spare set that can be efficiently swapped in just 30 seconds for extended missions, and recharged in one and a half to three hours, meaning virtually endless power if you ladder charging between uses. If you need constant power, there is a direct power option for the REVOLUTION as well as the PIVOT ROVs.

What sets the REVOLUTION NAV package apart is the addition of advanced piloting capabilities with USBL and DVL sensors. These sensors enable the ability to track the ROV on a map, log points of interest, draw a trail, plan missions, and even deploy autonomous routes with the mission planner feature. This means the NAV package can navigate to set targets and perform pre-programmed routes, allowing the pilot to focus on the camera and sonar feeds instead of the operation of the vehicle.

These sensors also have the capability to enable ‘auto-depth’ from the seafloor, as well as produce GPX and CSV files to house location data during operation. The NAV package also includes a service parts kit and an extended two-year warranty for a completely comprehensive experience.

The Blueprint MD multibeam imaging sonar is an optional add-on that conveniently mounts to the PIVOT and REVOLUTION for effective target identification in turbid waters. The M's high operational resolution features a peak frequency of 2.1MHz, an integrated velocimeter for improved accuracy, and a range resolution of 2.5mm for detailed close-range inspections. The MD short-range imaging provides the highest quality image in the M-series sonars and is ideal for up-close inspections.

Search and recovery missions are much more effective with an imaging sonar. ROVs that can also tilt the sonar are a huge advantage. This allows the operator to change the angle and optimize the field of view to fit any situation. The MD sonar offers high-quality imagery at ranges up to 30m (98ft). Experienced operators do not identify targets from further than 30m away from the target, which justifies the limited range of the M in comparison to the M750 and M370 sonars since the tradeoff is enhanced clarity for superior identification.

  • Battery Style
    • Removable batteries allow for spares to be had on hand.
    • Built-in batteries cannot be removed and generally cannot be replaced, leaving customers with no option but to purchase another underwater scooter when the battery expires or malfunctions.
  • Battery Availability
    • Brand-specific batteries don't allow for the use of off-brand batteries and users are subject to specific battery prices and availability in the market.
    • Some underwater scooter batteries are not available to be purchased separately or are not available in certain countries.
  • Battery Charging Times
    • Some scooters come with rapid chargers and others do not.
    • Charging times vary based on battery, but in most cases, charging can be expected to take 1.5 hours or longer.
  • Battery Runtimes
    • These can vary significantly based on battery size and scooter.
    • Some batteries may only run for about 30 minutes and others giving a combined time of up to 4 hours.

3. Underwater Scooter Buoyancy

Depending on the activity, buoyancy can play a critical role when selecting an underwater scooter.

Below are the three different types of buoyancy you will see referred to.

  • Negative Buoyancy
    • This is when the object in the water is denser than the water itself, causing the object to sink.
    • With a negatively buoyant underwater scooter, it is important to use a safety leash or tow line to prevent loss.
  • Positive Buoyancy
    • This is when the underwater scooter will naturally float.
    • Positively buoyant underwater scooters have the floatation built in or feature a removable accessory that provides floatation.
    • When let go of, this underwater scooter will float to the surface.
  • Neutral Buoyancy
    • This is when an underwater scooter is weighted just so that it will neither sink nor float, maintaining its position in the water, unless external forces act upon it.
    • This is commonly preferred by scuba divers where the diver's trim is paramount.

4. Underwater Scooter Speed and Thrust

You may think that speed and thrust are only directly related to the amount of excitement to be had, and while this is definitely a large factor when shopping for a thrill ride, there are some additional things to consider.

When considering speed and thrust for an underwater scooter, here are some key points:

  • Speed
    • Underwater scooter top speeds vary from around 0.89m/s | 2mph | 2.93ft/s upwards to around 4m/s | 9mph | 13.2ft/s
    • A higher speed means covering more ground and seeing more in a shorter amount of time.
    • Speed is related to the overall reduction of physical effort needed to reach distant locations.
    • No matter the speed, when underwater scooters are used in their highest speed setting, the battery depletes much faster.
  • Thrust
    • Thrust, or the power behind the scooter’s propulsion, is essential for maneuvering through strong currents.
    • A higher thrust allows for better control and stability, especially in challenging conditions, ensuring the underwater scooter can push through without straining the diver.
    • Thrust directly impacts efficiency as scooters with higher thrust can maintain a steady speed without quickly exhausting the battery.
    • Thrust can be a safety factor, as it allows users to quickly escape from risky situations, such as unexpected underwater conditions or avoiding obstacles.

5. Underwater Scooter Depth Ratings

Why do we care about depth ratings?

  • The depth rating is how deep an underwater scooter is rated for before no guarantee of continued operation.
  • Exceeding the depth rating will likely result in failure of equipment, permanent damage to the scooter, and possibly injury to self or others.
  • Underwater scooter depth ratings vary and can be seen as low as 5m | 16ft to as high as 182m | 600ft.
  • To avoid complications, determine your typical max operating depth or activity depths prior to purchasing an underwater scooter.

What about other ratings like temperature? Unless you plan to go ice diving or diving in near boiling water temperatures, these ratings are generally pretty standard.

If you are someone who is on the hunt for an underwater scooter that can handle depths up to 500ft and frigid temperatures, the Dive Xtras CudaX is currently our best option!

6. Underwater Scooter Modularity

Do you want an underwater scooter that can operate or be used in different capacities? If so, you should consider modular options.

Modular underwater scooters are those that can be used traditionally in diving or snorkeling one minute, then modified to be operated in an entirely different way such as on a paddleboard the next.

With a few modular options out there, the LEFEET P1 and LEFEET S1 PRO are the two most modular underwater scooters on the market.

7. Underwater Scooter Safety Features

Most underwater scooters come with at least one built-in safety feature, but some more come with more than others.

When looking at the safety features, first consider the user and activity. Below are some safety features that you will come across and should determine if they are wanted or needed.

  • Do I need...?
    • Physical Child Safety Locks or Trigger Locks
    • App-Enabled Safety Locks
    • Built-in Monitoring and Notifications such as Depth or Battery Alerts
    • Safety Start (Slow progression of speed upon activation)
    • Detailed Trigger Sequence for Operation (More than just a click and go)
    • Built-in Buoyancy
    • Propeller Cages or Guards
  • Automatic Shut-Off
    • Water intrusion or flooding of the battery compartment
    • Propeller intrusion or obstruction by foreign debris
    • Comes standard on most models.

8. Underwater Scooter Tech Features

As the world evolves and technology continues to be a staple in our daily lives, it is understandable that underwater scooters would start featuring more tech.

Below we look at two areas where technology may be a factor for you are when shopping for an underwater scooter.

  • Display and Monitoring
    • Most displays are still relatively small, and some are still using LED lights for battery status.
    • Underwater scooters now are beginning to feature large LED and LCD informative displays for tracking battery life, depth, temperature, warnings, and speeds.
    • Some underwater scooters feature a vibrating alert to compensate for the lack of display.
  • App-Enabled Underwater Scooters
    • App-enabled underwater scooters give users the option to monitor their device's status and, in some cases, allow changes to be made.
    • Some models allow sharing usage statistics with others.
    • App-Enabled models give parents better control with child locks and child-use monitoring.
    • Some smart device apps have been said to be unreliable and not worth use indicating that whether or not a scooter is app-enabled or not shouldn't be a deciding factor.

Will My Underwater Scooter Come with Warranties?

Yes, all underwater scooters should come standard with warranties. If it doesn't, we highly recommend purchasing one that does and always taking the time to review the policy.

By leveraging our experience, resources, and network we are usually able to assist with troubleshooting and can resolve most issues, however there are some cases where we may need to escalate and put you in contact with the brand.

Do Underwater Scooter Reviews Matter?

Yes, reviews and recommendations play a big role in purchasing the right underwater scooter for you. 

However, it’s crucial to pay attention to how an underwater scooter was used, for what, by who, and, if available, for how long.

If you're seeking a scooter for pool use, but someone attempted to take it wreck diving beyond its depth rating, this doesn’t mean the scooter isn’t any good, it just means that it wasn’t suited for that particular task.

Is there a place where I can read real underwater scooter reviews? Yes, we have a whole page of real customers who have reviewed underwater scooters we carry.
