This $500 Underwater Scooter Might Be the Most Fun You’ll Have All Summer

If you’ve been hunting for a solid underwater scooter that doesn’t cost a fortune but still packs serious performance, the Asiwo Manta might be exactly what you’re looking for. It’s not just a toy for splashing around in the pool — this thing has some muscle. With dual motors, a sleek design, and user-friendly controls, the Manta is turning heads among snorkelers, divers, and water lovers who want to step up their underwater adventures without breaking the bank.

Let’s break down why this compact beast is making waves and why it might be the best bang-for-your-buck sea scooter out there right now.

Built for Speed, Designed for Fun

Right out of the box, the Manta means business. It boasts dual thrust motors capable of pulling you through the water at up to 5.6 km/h (about 3.5 mph). For context? That’s faster than most recreational scooters in its price range, and underwater, it feels even faster thanks to water resistance. You're not crawling through the ocean — you're cruising.

And you’re in control. The Manta gives you three speed modes, letting you switch between a relaxed drift and a full-speed dash depending on how you feel and where you are. Exploring a reef? Go slow and take it all in. Feeling like Aquaman? Kick it up and fly.

Battery That Keeps Up with Your Adventure

Now, let’s talk about battery life — because no one likes being cut off mid-swim. The Asiwo Manta delivers with a powerful 4400mAh lithium-ion battery that gives you up to 35 minutes of use at full throttle, and even more if you’re taking it easy. It’s enough to enjoy a solid snorkeling session, cruise a reef, or dive down a few times and still make it back with juice to spare.

Better yet, the battery is detachable and rechargeable, which means if you snag a second one, you can double your water time with a quick swap. No waiting around hours for a charge — just pop in a fresh one and get back out there.

Charging takes around 2–3 hours, which is pretty standard for this class of underwater gear. Not instant, but fast enough to get back out by the next dive.

Depth? No Problem

The Manta doesn’t shy away from going deep. It’s rated to a maximum depth of 50 feet (15 meters), which is perfect for most recreational dives and more than enough for any snorkeler or free diver.

This isn’t just a pool toy — the Manta is meant to hit the ocean. Whether you're skimming along the surface or diving down to get up close with coral and marine life, it’s built to perform.

Compact, Travel-Ready Design

One of the Manta’s big wins? Its size. This thing is compact and lightweight, making it ideal for travel. It weighs in at about 7.7 lbs (3.5 kg), so you can toss it into a carry-on, backpack, or beach bag without much hassle.

It’s shaped for easy handling too — not too bulky, but sturdy enough to grip comfortably with both hands. It also features dual propeller covers, keeping your fingers and hair safe from spinning blades, which is a must, especially for younger users.

If you’re flying somewhere tropical and want to bring a scooter along? This one won’t give TSA a heart attack. Just check the airline’s policy on lithium batteries and pack it properly.

User-Friendly Controls

The Manta was clearly designed with usability in mind. It’s got a two-button trigger system — one on each side — so you need to press both to activate it. That’s a built-in safety feature to prevent accidental launches. Let go of either trigger and the scooter instantly cuts power.

There’s also an LED battery indicator right on top. You’ll know exactly how much power you’ve got left while you’re still in the water. No guessing. No surprises.

Positively Buoyant = Stress-Free Riding

Here’s a big plus for new riders or families: the Manta is positively buoyant, which means it floats. If you let go, it won’t sink into the abyss. It gently rises to the surface, making it easy to retrieve and almost impossible to lose. That’s peace of mind, especially if you’re using it around kids or in deeper water.

GoPro Mount for Underwater Content Creators

Want to film your underwater adventures? The Manta’s got you covered with a built-in GoPro mount, so you can attach an action camera and start recording your ride. Capture reef dives, turtle encounters, or just cool tricks in the pool. For content creators or social media fans, this feature is a total win.

Who Is the Asiwo Manta Best For?

If you’re a recreational snorkeler, traveler, or casual diver who wants a strong mix of power, portability, and price, the Manta fits the bill. It’s fast enough to be fun, light enough to take anywhere, and powerful enough to hold its own in open water.

It’s not a hardcore professional-grade DPV — but at around $400–$450, it doesn’t try to be. You’re getting excellent performance for the price and a scooter that can keep up with most casual-to-moderate underwater adventures. Plus, it’s beginner-friendly, making it a good starter option if you’re new to sea scooters.
