In this article, we’re checking out one of the coolest aqua gadgets in the world – the underwater scooter. Have you ever dreamed of jetting around underwater like a dolphin? Well, that’s a very specific dream, but it’s possible! An underwater scooter is a handheld tool that helps you propel you through the water with ease.

Product Reviews

Let’s get right into our product reviews. It’s worth noting that there’s a wide variability when it comes to sea scooters. They are very much divided based on power and capability, so that they are accessible at many different price ranges. We’re looking at a bunch of different choices so you can get a good idea of what’s available.

Best Overall Choice

1. Yamaha RDS250

Let’s start with our best overall pick. The Yamaha RDS250 comes from a trusted brand, and it’s our top pick because it’s an excellent blend of value and performance. There are more powerful scooters, but you can’t do much better for this price.

It’s a highly capable machine. Rated to a depth of 100ft (or 30m), this thing carries a consistent speed of 2.5mph. It’s perfect for underwater assistance while snorkeling, scuba diving, and just having fun!

The battery lasts for up to 2 hours on a charge, which is pretty solid for a sea scooter. It can handle lengthy expeditions on a single charge, and works great in both saltwater and freshwater.

Overall, it’s our top pick because it’s so functional and highly intuitive. Great speed, great battery life, and reliable performance from a trusted brand. Basically, it’s the best you can do for this price.

Pros

  • 2-hour battery life.
  • Speeds up to 2.5 mph.
  • Great performance in salt and freshwater.
  • Highly durable and leakproof (no flooding).
  • Camera mount for GoPros.

Cons

  • Not the most powerful sea scooter.
Best Budget Choice

2. Yamaha Seascooter

Our top budget pick also comes from Yamaha. We chose it as our top budget pick because you simply can’t beat the price.

But do take note that this is not a sea scooter which was designed for ocean use. It is designed very much for recreational use, and should be kept to shallow waters and pools. But for these purposes, we think it’s great!

It’s only suitable for depths of around 15 feet, so definitely keep it in the pool or the shallows. It reaches speeds of 2mph, so you can jet around the pool with ease.

Also, since this product is suitable for children, it has safety features to keep the fan secured.

Overall, it’s a quality discount choice. Just be sure that you want a sea scooter for recreational purposes. This is not the one for scuba diving or snorkeling!

Pros

  • Inexpensive sea scooter.
  • Great for recreational use.
  • Safety features for kids.
  • GoPro mount.
  • Speeds up to 2mph.

Cons

  • Not for deep waters or scuba diving/snorkeling.
  • Battery needs maintenance every 3 months.

3. WINDEK SUBLUE Scooter

WINDEK SUBLUE Scooter

Here’s a fun product from WINDEK. The first thing you’ll notice is probably the dual propeller system. This is ideal for balancing power with stability. The propellers on either side help stabilize the rider, and is even intuitive for kids.

It’s a powerful machine, but definitely more geared toward recreational use. It’s rated for 40m in depth, but it’s not quite durable enough to last at those depths for too long. It’s definitely better used as a recreational toy for pool fun or shallow water snorkeling.

It boasts an impressive top speed of 3.36 mph, making it quite quick for this price range! Additionally, it has a detachable head for extra aerodynamics.

Overall, it’s a capable machine for an affordable price. Definitely geared toward recreational use, so don’t expect a behemoth. But for the price, it’s a great sea scooter.

Pros

  • Great value.
  • Impressive top speed of 3.3 mph.
  • Lightweight – only 3.5 kgs.
  • Dual propeller system for extra speed and stability.

Cons

  • Not the most durable materials – keep out of deep waters.
  • Only 30 minutes of battery life.

4. TUSA-SAV Scooter  

TUSA-SAV Scooter

Check Latest Price

This is an impressive underwater scooter from Japanese manufacturer TUSA.

This scooter is unique in that its designed to fit between a diver’s legs, propelling them along and keeping their hands free. Check out the video below to see how it works.

This scooter places a definite emphasis on durability and functionality. It is depth rated up to 230 feet, which makes it suitable for scuba divers. The motor and internal assembly are well-protected, and you can definitely trust it in those depths.

It’s not the fastest scooter (2.6 mph top speed) but it hits these speeds reliably and consistently. What’s more notable is the control you have over the speed. The 3-speed propeller allows for consistent adjustments while in motion. It even has enough torque to pull 2 divers at once!

Overall, it’s definitely one of the most durable options on our list. It’s built with superior construction and can be trusted for scuba-level depths.

Pros

  • Hands-free riding – scooter propels the rider’s lower body.
  • Very durable and depth rated for 230 feet.
  • 80-minute battery life.
  • Impressive torque can pull 2 divers at once.

Cons

  • Not quite as fast as other premium sea scooters.
  • Very expensive.

5. WINDEK Seabow Scooter

Here’s another one we like from WINDEK. This is their more “premium” offering compared to the one we examined above.

This one is WINDEK’s superior option in every way, and it’s definitely an impressive machine. It’s rated for depths of 40 m (131 ft), which makes it quite suitable for certain scuba divers, and all types of snorkelers and swimmers.

It performs well, and sports dual-propeller design for added stability. It reaches speeds of 4.47 mph, which is very impressive for a scooter in this price range. It zips around with ease, and is easy to pick up and use.

We do with it was a bit more durable. The materials aren’t quite the highest level of quality. It stands up to regular use, but don’t expect it to last years. A definite focus was put on speed and power over durability, but that’s also why the price tag is so reasonable!

Pros

  • Fast scooter (4.47 mph max speed).
  • 60-minute battery life.
  • Depth rated for 40 m.
  • Affordable price tag.
  • Compatible with most action cameras.

Cons

  • Not the most durable construction.
  • More suitable for recreation use than deep diving.

6.  Yamaha RDS300

Yamaha RDS300

Check Latest Price

We know this list is heavy on Yamaha, but we just like their products so much. Their line of sea scooters are well-built, highly functional, and well-priced. This one is no exception.

The RDS300 is a step-up over the RDS250 we examined above. Mainly, it has upgraded power. It goes faster, reaching speeds up to 3 MPH. It also has a 2-level rotational speed control system. The one downside is that this increased power actually means a shorter battery life, at 90 minutes/charge.

Aside from that, it’s pretty similar to the RDS250. Both models feature impressive levels of durability. Both also have removable buoyancy components. Both options also have rubber hulls and floodproof construction.

Overall, just another solid option from Yamaha.

Pros

  • Up to 3MPH max speed.
  • Well-priced for what you get.
  • Very durable design, rated for up to 100 ft.
  • Heavy-duty rubber hull.

Cons

  • Shorter battery life than other Yamaha models.
Best Premium Choice

7. Yamaha YME22500

Yamaha YME22500

Check Latest Price

Let’s take a look at our “best premium” option. This is the best product we could find within the premium price range. And no surprise, it’s another one from Yamaha!

This is definitely the most powerful of Yamaha’s offerings. It’s designed for both professional and recreational use. It is a clear upgrade over Yamaha’s other offerings, and that includes price!

This machine has 500 watts of power, and can reach a top speed of 4.35 miles per hour. It has a battery run time of 90 minutes, and can reach depths of 130 feet (ideal for most scuba dives).

Best of all, it is reliable and solidly built. It has superior flood protection over the other machines on this list, and is backed by a reputable brand with reliable customer service. A clear choice as the best “premium” option.

Pros

  • Durable and built to last with superior flood prevention.
  • 90-minute run time.
  • 500 watts and 4.35 mph max speed.
  • Sleek and aerodynamic.
  • Up to 130 feet depth.

Cons

  • Premium price tag.
  • Not ideal for extra deep scuba dives (beyond 130 ft.).

8. WINDEK Electric Kickboard  

WINDEK Electric Kickboard

Check Latest Price

We like to mix these lists up a bit, so here’s a product that is more suitable as a stepping stone toward the underwater sea scooters.

This electric kickboard is designed as a swimming aid, or just a way to have fun propelling yourself across the water’s surface. Think of it like a sea scooter for skimming the water’s top.

It’s suitable for kids and adults up to 220 lbs. It provides 5KGFof thrust for quick movements across the water.

This is a great option if you’re not quite confident enough to use an underwater scooter, and still want the fun of a hand-held water propellant.

Pros

  • Great for beginners or for recreational use.
  • 5kgf of thrust.
  • For kids and adults!
  • Great as a “stepping stone” toward underwater scooters.

Cons

  • Can’t go underwater!

9. AQUAROBOTMAN Underwater Sea Scooter

AQUAROBOTMAN Underwater Sea Scooter

Check Latest Price

We’ll round out our list with an affordable, versatile option. The AQUAROBOTMAN scooter is a versatile scooter for recreational use.

It’s extremely easy to pick up and play. Simply hold on, pull the trigger, and you’re jetting along. It’s actually surprisingly quick, at 4mph, and the battery lasts up to 100 minutes.

If you’re looking for a scooter that has that fun factor, we think this one is it. It’s just so easy to hold, and the high speed feels great. There aren’t many scooters more fun than this one.

But keep in mind that it’s not the most durable scooter, and definitely not suited for scuba diving depths. It will hold up fine for recreational use, but you don’t want to push it too deep.

Pros

  • Easy to hold and use.
  • Quite fast – up to 4mph.
  • 100 minutes of battery life.
  • 3 camera mounts.

Cons

  • Not the most durable, not suited for great depths.

Sea Scooter Buyer’s Guide

Sea scooters are devices for underwater use. They utilize propellers to allow the user to travel underwater efficiently. They are usually hand-held, and help to propel the user underwater, assisting them with swimming, snorkeling, scuba diving, or other underwater activities.

Sea scooters are not designed to pull the user on their own, but rather to assist the user with swimming and with underwater transportation. This is particularly useful when the user is wearing heavy scuba gear.

Sea scooters come in many different makes & models, and differ based on power, design, durability, and more.

Factors to Consider in Buying

Before we wrap up our article, we want to help you make the best choice among the sea scooters above. We know we gave you a lot of options, and you might even be a bit overwhelmed. Evaluate these factors to sort through the options and pick the best one for you:

Depth

Depending on how you plan to use your sea scooter, depth will be a big consideration. Depth is mostly influenced by durability of design. The sturdier your scooter, the more it can stand up to the pressures at great depths.

Scooters will clearly mark their depth limits. Most sea scooters which are intended for professional use will reach depths of about 130 ft, which is typically considered the maximum depth for a recreational scuba diver.

Speed

Let’s get one thing out of the way – sea scooters aren’t meant to go extremely fast. They’re mostly meant to assist the user with swimming, scuba, snorkeling, etc. But with that being said, there still are a wide range of speeds available.

The most common speed range for sea scooters is between 2-4mph. It largely depends on the power of the propeller, but will also be influenced by your size and the weight of your gear.

The difference between 2 and 4mph is very noticeable! But the devices do tend to get more expensive the faster they go.

Also watch out for speed control settings. Sea scooters typically have 2 or 3 speed settings, but the more the better. You don’t want to go fast all the time, and it’s good to have the option when you want to slow things down.

Battery Life

It goes without saying that more battery life is better. The longer you go between charges, the more functional the machine. Typically, quality sea scooters will offer between 60-120 minutes of battery life.

Do consider that more battery life might also mean a heavier battery, meaning that you might sacrifice some portability in pursuit of longer scootering sessions. Also, longer battery life means a higher price!

However, generally speaking, you’ll want to aim for more battery life if you can. This is especially true when you consider that batteries lose longevity over time.

Durability

Of course, you want to consider a device’s durability. This is particularly important with sea scooters, because they need to stand up to the water pressure of great depths. They also need to be extremely well water-proofed to protect the interior components.

Look for a machine made with heavy-duty materials, and one from a trusted manufacturer. Also, it never hurts to check out customer reviews to see how the devices hold up to extended use. We made sure to comment on each device’s durability in our reviews above.

Conclusion and Top Pick

Thanks for reading through our guide to sea scooters! As you can see, there are so many awesome options available. We hope we’ve given you all the info you need to make the best choice.

Our personal favorite is the Yamaha RDS250. We think this model offers the perfect blend of functionality, durability, and price. It reaches a nice top speed, it’s strong and durable to withstand depths, and the battery lasts a solid 2 hours. On top of that, the price is right, and we think it’s the best bang for your buck!

That being said, sift through our list to find the best option for you. After all, the best sea scooter is just your personal favorite!
