Underwater Scooters Reviews

1. Yamaha 275L

The rugged design combined with its impressive speed, easy control, and many features make the 275L our top recommendation. This is an FAA approved product that you can even take with you in your bag when you travel by plane, which means that you can take it with you when you are on vacation at the seaside to enjoy awesome scuba sessions. In the package alongside it are included the SLA battery which powers it, a charging pod, and four ballast weights. Furthermore, the manufacturing company covers it against defects the first 6 months after you purchase it.


Due to the performance it provides and the design it boasts, it is recommended for use by people over the age of 16. It measures 28 inches in width, 12.6 inches in height, and 12.6 inches in depth, so if you take it in your bag when you travel, it won’t occupy a lot of space. Furthermore, as it weighs only 32 pounds, it will be easy to carry. Another element that adds to ease of transportation is the carry handle it features. The product is powered by a 12V sealed lead acid battery that takes only 6 hours to charge.


As aforementioned, it is powered by a rechargeable battery that takes approximately 6 hours to “juice up”. When fully charged and when you use it at normal speed rates, it provides up to 120 minutes of continuous runtime, so you can enjoy lengthy diving sessions with it. Another pro is the fact that it provides an impressive 50-minute runtime when the battery is full and you use it at the highest speed settings. There are a total of 3 different speeds that you can select between, and the top speed it can reach is 3.3 miles per hour. Additionally, the maximum depth at which you can go when using it is 130 feet, a depth that you would have probably not reached without it.

Mention Worthy Features and Specs
  • Rotational speed control ensures an easy time changing the speed setting.
  • Onboard battery indicator light keeps you updated with the current power level of the battery.
  • Carry handle makes it convenient to transport.
Safety and Convenience

The quality flood prevention system it features ensures this product will give you a run for your money as it will remain in a perfect shape for years to come. As it features an automatic buoyancy adjustment system, you will enjoy a highly convenient manner to use it in saltwater. The 3-level rotational speed control ensures ease of use when it comes to selecting the speed at which you want to go with it. For safety purposes, it features an automatic shut-off that activates when the trigger is released. In case ingress occurs, it sends off an audible alarm to alert you of the situation. Furthermore, it comes with a LED indicator that shows you what is the current status of the battery so that you won’t be caught off-guard mid-diving session.

  • Allows use in saltwater due to its automatic buoyancy adjustment system
  • When water ingress occurs, it sends off an audible alarm to alert you
  • FAA approved battery enables you to even take it on flights to your tropical vacation destinations
  • Weighs 32 pounds – a bit heavier when compared to other DVPs

As it allows up to 120 minutes of continuous use as long as you do not overdo it with the speed, this is a must-have for those who feel in their element when they are in an aquatic environment. Reasonably priced and featuring a plethora of safety elements, it is our top recommendation to you.

2. Yamaha RDS300

Light yet powerful, the RDS300 from Yamaha gives you up to 90 minutes of underwater enjoyment if you are going at a steady speed, and approximately 30 minutes if you want to go full speed ahead. Recommended for those over the age of 16, and capable of reaching a top speed of 3 miles per hour, it is one product we recommend and trust.

When it comes to the maximum depth it can reach, expect to go as low as 100 feet underwater with it. This depth reaching capability exceeds industry standard, so we have to highlight it. It features a GoPro mount where you can place the camera and take beautiful shots and recordings of your aquatic adventures.

For your safety, it automatically shuts off when the trigger is released, so there is no need to worry about these aspects. Furthermore, it features a water leak sensor that announces you in case any mishap occurs with the propulsion vehicle.

  • Can reach 100 feet below water at tops
  • Accidental flooding is prevented by its waterproof construction
  • Automatically shuts off when the triggers are released
  • Weighs only 18 pounds – won’t be hard for you to maneuver it
  • Can reach a maximum speed of 3 miles per hour
  • Can take as much as 8 hours for its battery to fully recharge

Fast despite its compact size and light profile, this Yamaha entry provides up to 90 minutes of underwater fun and enjoyment. It is designed with safety and durability in mind, the auto shut-off and waterproof construction being proof of this statement’s validity, and it comes at a surprisingly reasonable price as well.

3. Sea Doo GTI SD5540

This Sea Doo entry measures 23.5 inches in width, 14.6 inches in height, and 12.2 inches in depth, and it weighs only 18 pounds, which makes it easy to use and maneuver when you are having fun snorkeling or scuba diving. It might take up to 8 hours for its battery to fully charge, but when the battery power is full, it provides up to 120 minutes of run time if you go at a medium speed.

However, if you want to speed up things and go for the maximum speed during your ride, the battery will only last approximately 60 minutes. Speaking of speed, it can reach a top speed of 2.5 miles per hour, which is more than what expected from most of these products. With it, you can go 100 feet deep at tops, so keep this aspect in mind as it does provide more than most models do.

For durability enhancement, it features a rotation propeller cage cover. Additionally, the manufacturing company provides a 6-month warranty for it, a period during which you can have it fixed or replaced free of charge. Add to these elements the convenient pricing, and you get one tempting sub-aquatic scooter.

  • Provides up to 120 minutes of continuous use at medium speed
  • Recommended for people over the age of 16
  • Reasonable price to quality ratio – one of the more affordable options to go for
  • You can reach a maximum depth of 100 feet with it
  • Can reach a top speed of 2.5 miles per hour
  • Takes approximately 8 hours for the battery to charge

Able to last for up to 120 minutes of continuous underwater use, it is one of our top recommendations not only due to its great overall performance, but due to the fact that it is backed by a generous warranty and that it comes at a reasonable, affordable price as well.

4. Sea Doo Dolphin SD5542

We must start our review by mentioning the spectacular design – it measures 19 inches in width, 11.25 inches in height, and 11.25 inches in depth, and it weighs a mere 12 pounds, thus being one of the best options for children. As a matter of fact, it is recommended for those over 8 years old, so it is fun for the whole family.

Although it is one of the cheaper entries on the market, performance is not sacrificed for the convenient pricing at all. It can reach a top speed of 2 miles per hour to help you reach the underwater point where you want to dive or snorkel fast, and the battery provides up to 90 minutes of continuous use if you go at a normal speed.

Unfortunately, there is a minor downfall, more precisely the fact that it can reach a top depth of 15 feet, which is less than what other models provide. However, it makes up for this flaw with its 6-month warranty, a period during which it will be repaired by the manufacturing company free of charge.

  • Weighs only 12 pounds – one of the lightest entries in the market
  • Features a GoPro mount where you can place the camera to record your adventures
  • Can be used by children as well – recommended for those over the age of 8 years
  • Takes only about 6 hours for the battery to fully charge
  • Safety lock enhances safety in use
  • Can only reach 15 feet deep underwater

Affordable and easy to use due to its light profile – it weighs only 12 pounds -, this is one of our top recommendations for those who have children and want a product that the whole family can enjoy. It might have some minor flaws, like the limited 15-foot depth reach, but the design and overall performance make up for any lacks.

5. Sea Doo Aqua Ranger SD95001

The design recommends it for use not only by adults but by small children as well, more precisely those who are over the age of 8. It measures 20.5 inches in width, 10.3 inches in height, and 11 inches in depth, and it weighs only 11.5 pounds, so maneuvering it while diving or snorkeling is a cinch.

The top speed it can reach is 2.5 miles per hour, and you can adjust the speed it goes at to your liking for an even more pleasurable experience. Unfortunately, with it you can only go 30-feet deep, which for those who have a more adventurous style could be a drawback. For the battery to fully charge, it takes approximately 6-8 hours.

On a full battery charge, it provides up to 90 minutes of continuous use at a medium speed, and approximately 30 minutes if you go at full speed throughout the entire diving session. It comes at one of the best prices possible, so we strongly recommend it to those who are on a budget. Furthermore, it is backed by a rather generous 6-month warranty.

  • Capable of reaching a top speed of 2.5 miles per hour
  • On a full charge, it provides up to 90 minutes of continuous use
  • Recommended for adults as well as children – those who are over 8 years old
  • Speed control allows you to decide how fast or slow you want the diving or snorkeling session to go
  • Great price to quality ratio – an affordable option to go for<
  • Only allows you to go 30 feet deep underwater when using it

Despite the cheap asking price, the Sea Doo is one of the best performing products in the niche. It can reach a generous 2.5 MPH top speed, and it provides up to 90 minutes of continuous use. Best of all, it is appropriate for use by children as well as adults, so you and your entire family can enjoy using it.

6. Yamaha RDS250

A compact and lightweight model, yet one you can confidently go for as it will make your aquatic adventures more fun, the RDS250 will make you fall in love instantly. It measures 24 inches by 15.2 inches by 12.3 inches, and it weighs only 18 pounds. It comes with a sealed lead acid battery that provides a maximum of 2 hours runtime when used at a normal speed. As it is rated for depths of up to 100 feet, you can explore as much as you like with it.

Of course, we cannot overlook the 2.5 miles per hour speed that is sure to “wow” you and help you explore the water faster than ever. What makes it all the more pleasing is the fact that it can be used in salt water as well, all due to the removable buoyancy control chamber it features.

It is recommended for use by people over 16, so you and your kids can have a ton of fun with it. Furthermore, it features a standard GoPro mount so that you may place your camera here and record your adventures.

  • Provides you with up to 2 hours of continuous use when the battery is full
  • Compact and lightweight – easy to carry around and use
  • Boasts a waterproof construction which ensures accidental flooding won’t occur
  • Can be used in salt water as well as freshwater
  • Can reach depth of up to 100 feet with it
  • Could have boasted a higher maximum speed

Versatile in use due to its compatibility with salt as well as freshwater, the RDS250 is a model we could not overlook. Not only will you go as deep as 100 feet underwater with it, allowing you to explore areas you otherwise would not have been capable of exploring, but it can service you for up to 2 hours continuously before the battery runs out of power.

Care and Maintenance Tips for First-Time Owners

Despite their slim profile that might have you thinking there is no need for much maintenance work and care, sub-aquatic scooters actually do need your attention from time to time. As this is an investment you surely do not want to ruin after only a few months of use, we advise you to follow the care and maintenance tips for the battery and the device itself provided in the following lines.

  • Battery Care

  • Remove the battery when it is not in use;
  • Store the battery in a well-ventilated area;
  • Keep the battery away from children and pets;
  • Make sure you do not place it near a heat or ignition source;
  • Use the supplied charger for the battery recharging task;
  • Do not use or charge the battery when temperatures are over 104°F;
  • Charge the battery within 24 hours of power depletion or use;
  • Fully charge the battery before inserting it;
  • If it appears damaged or does not charge fully, replace it;
  • Wait approximately 30 minutes after you charge it before placing it back.
  • Post-Use Care

  • Take it out of water when you are not using it;
  • Rinse it in fresh water and let it dry before storing it;
  • Keep the interior housing dry at all times;
  • Open the ventilation plug in the nose cone when storing it for long periods of time;
  • Store it vertically or in a position that does not allow deformation to the propeller nozzle;
  • Never use detergents or soap to clean it;
  • Open the nose cone and allow gases to dissipate before connecting or disconnecting any cables to it or its battery.

Safe Use Recommendations

Although it might be fun to use, and depending on the model you buy, even designed for the entire family, there are a few guidelines you should follow to make the experience as safe as possible and eliminate the possibility of any mishaps or injuries. Stick with us to learn what these safe use recommendations are, and obviously, apply them to make the most out of your snorkeling or scuba diving sessions.

  • Do not stray too far from the shore: While the purpose is to take you away from the shore fast and in a convenient manner, you should not push its limits, or you might risk drowning. When using it at the seaside, do not stray too far from the shore, more precisely go as far as you would have gone if you were to swim there. This way, in case it runs out of battery, you can safely return to the starting point.
  • Do not go deeper than listed on its spec sheet: There is a good reason to why the maximum depth range appears on the specification sheet of the product. If you go deeper than recommended on it, you might actually do irreversible damage, thus not being able to resurface with its help. Another tip to keep in mind is to never go deeper than you feel comfortable at your current skill level.
  • Always keep an eye on battery life: If the device features a battery life indicator, keep an eye on it as it shows how much time you have left using it. When the alarm is sound off or the LED flashes, indicating that the battery is running out of power, you can start returning to the surface and go back to the starting point as there is not much “juice” left in the device.
  • Set a safe speed for your skill level: One thing you must always remember is to not push your limits as the aquatic environment is no laughing matter. With this being said, always make sure you set a safe speed for you and your current skill level. Do not use the top speed setting if you feel uncomfortable with it or you feel overwhelmed, as it is more important to stay safe than show off.
  • Keep your hair away from it: If you have long hair, tie it up or wear a swimming cap when using it. This way, you prevent your locks from intermingling with the propeller and causing you harm, which could even lead to drowning if you are not careful.
  • Respect the age restriction: Each model shows, on the specification sheet, for what age it is recommended. If it says on the spec sheet that it is recommended for people over the age of 16, for example, do not let children smaller than this use it as it presents a danger to them.
  • Supervise children when they use it: If the model you bought is appropriate for use by children of your children’s age, you can let the small ones have fun with it. However, you must always supervise them when they are using it as children tend to not always obey the rules, which could cause them serious injuries and put them in harm’s way.
  • Beware of loose clothing and jewelry: Make sure you never wear loose or flowing clothing and jewelry when using the propeller as these items could get drawn into the propeller, thus causing an unwanted accident to take place.
  • Inspect the swimming area: Before you start your adventure, check to see if there are any major obstacles along the road if it is possible. This way, you know to avoid them when approaching that specific area, or, if it is possible, you choose another area to swim in completely.
