Best Underwater Sea Scooters Review

best underwater sea scooter diver propulsion vehicle

Divers should avoid any unnecessary movements to keep their oxygen consumption and heart rate to a minimum. With that in mind, what if there were something that does all of the heavy lifting so that you don’t have to lift a finger? Thankfully, a solution already exists and it is a diver propulsion vehicle (DPV), more commonly known as an underwater sea scooter.

The best underwater scooter will use its propellers to carry you large distances and help you conserve precious oxygen. With the help of its powerful motor, you will pierce through the water like a torpedo and find many beautiful locations to explore. By conserving your oxygen, you can spend more time exploring cool caves and wrecks instead of wasting precious resources just trying to get from point A to B.

What’s more, underwater scooters are highly versatile. They can be used in both shallow and deep depths. They can be used by snorkelers or swimmers that want to conserve their energy as they explore a huge barrier reef. They can help you maneuver more easily through currents, and they are not just practical but extremely fun to use.

When searching for an underwater scooter, keep in mind there is a big difference in what budget models and high-end models can do. Generally, the higher the price tag, the better the battery life, speed, and depths that you can dive with it.

As such, the vast majority of divers don’t need to get the latest, most expensive high-end model to meet their needs. Below, we have compiled a list of the best underwater scooters on the market so that you can find a great one without breaking the bank. We have also compiled a buying guide in case you want to do some research on your own.

Best Sea Scooter Buying Guide

best affordable sea scooter

Size

The size and weight of an underwater scooter affects its underwater performance in numerous ways. The average recreational prefers using smaller, compact scooters. A streamlined design makes it easier to bring the scooter along in carry-on cases or backpacks when traveling to remote destinations. However, smaller scooters do not perform as well as larger scooters.

Large scooters are bulkier and heavier but they house more powerful propellers and motors. Therefore, they are able to go faster and deeper than their smaller counterparts. While every model has different specifications, larger scooters tend to perform better and increase a diver’s range. The downside is, obviously, that it is larger and therefore more cumbersome to carry around.

However, if you are diving locally, then even the largest tow-behind scooter can fit in the trunk of your car. If you plan on flying to your destination, then a compact scooter is necessary.

Weight

Similar considerations have to be made when it comes to how heavy a scooter is. You are going to be traveling with a lot of heavy gear, and if you have a travel BCD, then it is likely that a sea scooter will be the largest and heaviest item you will bring.

A heavier scooter makes it harder to carry while traveling but also has some repercussions when using it underwater. Keep in mind that a dive propulsion vehicle’s weight contributes to the overall weight of your scuba gear, which means you need to adjust your BCD to stay neutrally buoyant. A bulkier scooter can be harder to control underwater. Scooters that have a powerful motor and are lightweight will be expensive.

Type of Scooter

There are various types of underwater propulsion devices such as sub-skimmers and wet subs. With that said, those models are generally used by military personnel and you won’t find many such types for consumers. The most popular type of scooter is the tow-behind type.

Tow-behind scooters are essentially a pair of handles, a motor, and some sort of propeller. Its beauty is in its simplicity, and they are able to provide numerous benefits for you while diving.

Battery Life

Underwater scooters are battery-operated and can provide anywhere from 30 minutes to 4 hours of battery life. Furthermore, the time it takes to fully recharge the batteries can take several hours. In other words, once a battery runs out, you won’t be able to use the scooter anymore unless you have some spare batteries. Experienced divers will purchase backup batteries and bring them on extended immersions.

The type of batteries that most recreational sea scooters use are sealed lead acid batteries, which are more expensive but safer than traditional lead batteries. In order to charge them, they must be removed from the scooter’s housing. Some scooters use lithium-ion batteries, however they are still not as common as traditional lead acid batteries.

If you have your scooter running at full speed all of the time, then you will drain the battery much faster than if you moved at slower speeds.

Depth Rating

In terms of performance underwater, specifically depth ranges, there is an extreme variance in what each model has to offer. A scooter may only be rated for depths of only a few feet to several hundred feet. As you’d expect, a scooter that only has a 15 feet depth rating is going to be a lot cheaper than one with a 130 feet rating.

There are many factors in place that can affect their depth range as well, such as the scooter’s own buoyancy, which impacts whether it can efficiently sink or not. In the same way that divers strive to achieve neutral buoyancy by tweaking their buoyancy compensator, scooter manufacturers are aiming for neutral buoyancy as well.

Speed

Do you have a need for speed? Do you want to pierce through the water the way a shark, dolphin, or torpedo would? Are you planning on doing the underwater equivalent of drag racing with some buddies?

If you answered yes to any of these questions, then I have some bad news for you. Even the fastest underwater scooters don’t go very fast. The average speed is between 2 and 4.5mph, with the faster ones on the higher end of that range and the fastest may exceed 5mph.

With that said, while those speeds seem slow when compared to a car or plane, underwater it translates to a nominal increase in speed. Plus, the goal of these devices is to help you conserve energy, not to go fast.

Propeller Protection

In order to ensure your safety, all underwater scooters are held to a strict standard. Each device must have some sort of moving parts protection. In other words, there needs to be a cover – typically some sort of mesh panel or radial vent – over the propeller.

Some scooters provide additional protection against fishing lines and other underwater debris. Furthermore, fine covers are necessary for younger divers who might accidentally stick their fingers in the path of the oscillating propeller.

Durability

Anything that is exposed to saltwater needs to be durable. You want to find a sea scooter that is resilient and reliable enough to perform well even in rough conditions. When searching for a scooter, look for one that is constructed from sturdy polymer and corrosion-resistant material.

Furthermore, scooters designed to withstand the pressures of deeper depths will be more durable than ones intended for shallow water diving only. It needs to be able to propel you through underwater currents and robust enough to shrug off the occasional knock or two.

External Controls

Underwater scooters must have watertight and intuitive external controls. Typically, what this means is that the main power switch and speed regulator are easy to control. Both of these parts are integrated into the scooter’s steering system.

The scooter should start up immediately if two conditions are met: the power switch is turned on, and the speed trigger is held down. Once the trigger is released, the motor would shut off. So if you were to lose your grip on the handles, the scooter won’t get very far before it shuts off automatically.

Since any physical exertion increases air consumption, the triggers and buttons need to be easy to access and operate. Otherwise, the scooter isn’t benefiting you very much.

Hull Protection

The front of the scooter, or hull, is a critical but sometimes underappreciated component of the device. It is where the battery and all of the circuitry required to power the scooter’s motorized propeller is housed. This vital part of the scooter must be water and gas tight so that it can function properly.

Any leak, even minor, can damage the internals of the scooter. It can also affect the scooter’s buoyancy. That is why professional grade scooters include flood warning lights to alert divers that the scooter is on the verge of malfunction. You must keep an eye out for it otherwise your scooter may suddenly die on you.

Furthermore, the hull must be durable enough to endure the wear and tear of numerous underwater runs, perhaps several in one day. To ensure it is up to the task, manufacturers line their scooter hulls with impact-resistant materials such as rubber to protect the hull integrity.

Buoyancy

In the same way that divers need to be neutrally buoyant, underwater scooters must also maintain neutral buoyancy. Most high-quality and professional scooters will have ways to adjust its buoyancy. These generally consist of a weight system that includes buoyant attachments or removable weights.

When the scooter is neutrally buoyant, it means that it is floating in place, neither rising or sinking. This is important not just for conserving your energy, but ensures that the scooter doesn’t go sinking to the depths if you ever lose your grip on it.

A positively buoyant scooter makes it difficult for you to descend. However, snorkelers and swimmers may want their scooters to remain positively buoyant since they are spending their time at the surface. It also means that it won’t sink to the bottom if left unattended or when not in use. If lost, a floating scooter will be easier to find than one that has sunk to the bottom.

Price

The price of underwater scooters can range from, at the low end, a couple hundred dollars, and at the high end, several thousand dollars. Professional-grade models include advanced functionality such as speeds of 4mph, batteries that last for several hours, and depth ratings of several hundred feet.

How many of these features you want, as well as how high the metrics get, depends entirely on how much you are willing to spend. With that said, there are still numerous mid-range sea scooters that are quite competitive at an affordable price. Recreational scuba divers need not even think about getting an advanced model until they have more training and experience under their belt.

Even if you have the money to get the most advanced model, you may not even be capable of using it to its full potential if you only dive at shallow depths. Therefore, in order to take full advantage of your investment you need to determine your needs before spending more money than necessary.

Frequently Asked Questions

Do I need an extra battery for my underwater scooter?

Dive propulsion vehicles can help divers conserve their energy on a dive. However, how much it can help you is limited by the battery’s run time. The efficiency of its battery technology determines how long it can last before it needs to be recharged, as well as how long it takes to recharge it.

Underwater scooter manufacturers utilize energy-dense sealed lead batteries that provide 30 minutes to 2-hours of run time. Depending on how long you plan on diving, you may want to purchase additional batteries so that you can use your scooter for the entirety of your dive excursion.

If you wish to share your scooter with fellow divers, having a few extra batteries on hand doesn’t hurt. Spare batteries can keep the fun going for many hours. They are also a necessity in case a battery leaks or malfunctions in any way, you know that you have a backup. With that said, batteries need to be replaced every few years because their capacity to store energy depreciates over time.

How should I store my underwater scooter when I’m not using it?

Few people dive year-round; most dive only when it is seasonally appropriate. Thus, your scuba equipment will be in storage for several months of the year, and you need to do some minor preparations to ensure that your gear is stored properly.

Thankfully, how you store your underwater scooter is not much different than how you store your other scuba gear. After your final dive for the season, rinse it thoroughly and make sure you get all of the salt and debris off. Dry it with a towel and let it sit in a cool, dry area away from direct sunlight until it completely air dries.

Take out the batteries and make sure they are at half capacity before storing them. This will extend its life span and reduce the chances of leaking while in storage. Batteries do not like heat, so as we mentioned above, store it in a cool, dry area.

Batteries lose about 20% of their storage capacity every year no matter how well you maintain them. Thus, we recommend you make full use of your scooter before you need to store it. That is also why you should not purchase any batteries unless you plan on using them right away because time will only degrade them.

Once it is time to take your equipment out of storage, you will need to do a few checks. Look for any cracks, faulty seals, or battery leaks. Remember to charge your battery before your dive.

Are underwater scooters safe to use?

As you are aware, underwater scooters use propellers to carry you forward. This raises some safety concerns: are the propellers covered up? Does the scooter move at dangerous speeds? Diving is already an activity with lots of safety concerns, does using an underwater scooter increase the risks of an accident?

These are all valid questions. It is possible that these devices can propel a diver to intense depths that they are not used to. Without proper training, they may find themselves deep underwater with insufficient air to safely resurface. Conversely, divers may accidentally surface too quickly and pass out.

Here are the ways that underwater propulsion vehicles can avoid the pitfalls mentioned above. First, the propellers are indeed covered up so that fingers or any other appendages don’t find their way in.

Next, underwater scooters move at speeds of 2 to 4.5 mph. Even if you crash at full speed, you will survive. The speed is only an issue if you are ascending or descending very quickly.

Furthermore, underwater scooters will only move if these conditions are met: 1) the power switch is turned on, and 2) the speed trigger is held down. If you were to let go of the speed trigger, the propeller will stop and you will eventually stop as well. The speed can also be adjusted so that it does not accelerate very quickly. Thus, divers should be aware of how fast they are ascending or descending so they can adjust to the pressure changes.

Can I use a sea scooter for underwater photography?

You can use an underwater scooter to quickly cover large distances and get you to beautiful underwater vistas and locations like wrecks, reefs, and caves. If you are diving with photography gear, no doubt you are already weighed down heavily and have, at best, one hand free. Therefore, you should look for a scooter with a GoPro or universal camera mount.

Keep in mind that you need at least one hand on the scooter to operate the speed trigger. If you require both hands for a shot, or want to take a still, then you will need to turn the scooter off completely to do so.

What benefits do underwater scooters provide?

Are underwater scooters strictly necessary in order to enjoy scuba diving? Of course not. However, they do provide some useful benefits that could certainly enhance your diving excursion, such as:

  • Reduced air consumption: Swimming elevates your heart rate and thus causes you to use up your oxygen faster. With an underwater scooter, you can conserve most of your energy by letting the scooter carry you around instead. Having a reliable scuba regulator doesn’t hurt, either.
  • A way to fight against currents: Currents can appear underwater and swimming against it is an arduous task that should not be attempted under most circumstances. However, with the powerful motor of an underwater scooter, you can swim against strong ocean currents without exhausting yourself.
  • Improved range: Not only can you conserve energy, but you can also cover a larger distance in less time without tiring yourself out. This way, you can spend more time exploring beautiful locations instead of swimming around aimlessly.
  • Improved safety: Since an underwater can help you do all of the above, the net result is that you have more oxygen, time, and energy while diving. In other words, you are better equipped to handle any emergencies should they arise because you have more resources to deal with them.
  • A greater experience: Let’s stop talking about practical benefits for a second and focus on something that is often overlooked: how fun is it? We have to say, underwater scooters are just pure fun. They make you feel like a kid again. In the same way that driving can be relaxing, traveling with an underwater scooter feels like you are on a ride you don’t want to get off.

Who should use a sea scooter?

Sea scooters are highly versatile and nearly everyone stands to benefit from it. We have mainly focused on its practical uses for scuba diving. However, the people who stand to benefit the most from sea scooters are children, elderly, or anyone has trouble swimming.

There’s nothing wrong with only using the scooter at the surface with a life jacket on. If you don’t have the stamina to cover large distances, then let the scooter do all of the work for you. Furthermore, you can use a sea scooter just because it’s, you know, fun to use. It’s the perfect gift for kids, and honestly, there’s nothing wrong for anybody of any age to use it for a joyride.

With that said, if you plan on diving with one, then we recommend you have a solid grasp on your diving fundamentals before you rely on a sea scooter. It should not be used to cover any weaknesses in technique, but rather to make things more convenient for you.

Best Underwater Sea Scooter: Parting Words

Whether you are scuba diving, snorkeling or freediving, an underwater scooter is able to provide you with hours of thrills by taking you from point A to B very quickly. This helps you cover a large distance in a short span of time and take in more sights that you otherwise couldn’t. It also has the very practical benefit of helping you conserve energy, which is vital for scuba divers with a limited oxygen supply.

But what’s most important of all is how fun it is to hold onto one of these dive propulsion vehicles and letting it do all of the heavy lifting while you relax and enjoy the view. Everyone nearby is going to be jealous watching you zoom past them in style.

In order to find the best underwater scooter, you need to find one that suits your needs. Entry level models are designed only for casual use, and they have a limited depth rating of around 15 feet, run time of 1-2 hours, and propel you at speeds of 2-3 miles per hour.

The more money you spend, the more features you get, particularly a significantly improved depth rating. However, most people will not need to dive more than 15-30 feet, and so their money is better spent getting a basic model. Considerations should also be made if the sea scooter can fit inside a carry-on bag which makes traveling a lot more convenient.

Don’t let lack of stamina be the reason why you can’t fully enjoy your snorkeling or scuba diving adventures. Bring an underwater scooter with you and let it do all of the heavy lifting. By following the buying guide or choosing one of the scooters we recommend, you will be sure to find a solid product that will leave a huge smile on your face as you are effortlessly gliding through the water.
