1. SZJJX RC Mini Submarine

View on Amazon

Editor’s Rating: 4.2/5

My first pick is the perfect mini-submarine for kids to play with in bathtubs, pools, and ponds, etc. It’s affordable fun for anyone who wants an introduction to underwater remote-controlled crafts.

• Best feature 1: Safe for kids
• Best feature 2: Multiple propellers
• Plus points: 1m depth, 5m control range, built-in rechargeable battery, easy to use
• Minus points: Tiny, plasticky, limited power/use

The SZJJX RC Mini Submarine really is tiny. It’s safe for smaller kids to use under adult supervision. It’s small enough to play with indoors, which doubles its appeal as a practical toy. You can even cruise in a moderate sized fish tank or in the tub at bath time. The multiple propellers give it enough thrust to dive down to one-meter depth. It’s easy to use at any level too.

The 5m control range doesn’t sound much, but it’s plenty for a mini-submarine. Any further and you’d lose sight of it. There probably wouldn’t be enough power to bring it back either. I’d say the range is perfect overall. The battery takes about 20 minutes to charge, so there’s never long to wait between underwater adventures.

The Not so Good

I don’t want to pick too many faults because the SZJJX RC Mini Submarine is only a toy. It is small and plasticky, though, which is both good and bad. It’s good because you can play with it in tight spaces. It’s bad because it’s easy to step on or break by accident. And you won’t be able to use the SZJJX RC for much more than five minutes at a time between charges.

2. eMart Kids Mini RC Boat Submarine

Editor’s Rating: 4.1/5

My second pick is another great mini-submarine for youngsters. The eMart Kids Mini looks more like a conventional submarine than the previous pick. OK, let’s see what it does.

• Best feature 1: Good running time
• Best feature 2: Easy to use
• Plus points: Well made, bright yellow color, LED lights, fast charging time
• Minus points: Underpowered, shallow depth

The built-in lithium battery gives an impressive 20 minutes run time. That’s a huge advantage over the first pick. The yellow color of the Mart Kids Mini RC boat-submarine makes it easy to use and see from a distance. This is no small detail as tiny crafts like this can be easy to lose sight of in outdoor spaces. The maximum depth is unspecified, but you can expect at least 2.5 feet in calm waters.

The eMart kid’s mini RC submarine has a quality build despite being a toy. The sub comes with some colorful LED lights that let you use it in the dark. Bright lights have always been a big attraction on kid’s toys. The charging time of this puppy is another bonus at just 30 minutes.

The Not so Good

It’s a toy aimed at young kids so you don’t want it to be too aggressive or too powerful. Even so, it’s probably a tad underpowered. The slow speed of this sub will see some kids lose interest quite quickly. It won’t go down too far either. That will disappoint the kids attracted to deeper cruising.

3. Sub-Mariner Camera Submarine

Editor’s Rating: 4.7/5

My third pick is the Sub-Mariner camera, and it takes us to the next level. Compared to the toys above, it’s bigger, more powerful, and has filming capabilities. Let’s see what else it offers.

• Best feature 1: 3 channel control
• Best feature 2: Built-in camera
• Plus points: Agile, well made, built-in memory, LED spotlights
• Minus points: Small memory, tiny size, short ranges

This versatile yellow submarine targets an older audience with more serious intentions. It’s still small and toy-like, but it’s not a bathtub plaything like the first subs on this page. This agile beauty is well built and so at home in the water. It floats, dives, climbs, reverses, and turns with grace and ease.

The built-in camera has 1280 X 960-photo quality and 640 X 480 VGA video. There’s also built-in memory to capture all your underwater footage. Another nice touch is the two front-facing powerful LED spotlights to illuminate the way ahead.

The Not so Good

Captains of this sub don’t expect to take award-winning, feature-length video or prize photos. That’s just as well with only 256MB of inbuilt memory. The camera’s capability still offers a great introduction to underwater photography and videography. This sub is also tiny, a lot smaller than the advertising portrays it. It’s still excellent value, but make sure you know what to expect.

The final gripe for the Sub-Mariner camera sub is its distance and depth ranges. The control range is supposed to be 5m, but that’s wishful thinking. I wasn’t able to find the actual depth range, but it too is disappointing. It’s a great vessel if you don’t want to go too deep or too far. The instructions are all in Japanese, which is why some of the finer details are missing.

You do have other options if you want to submerge deeper and cruise further.

4. Sea Doo Dolphin Personal Dive Submarine

View on Amazon

Editor’s Rating: 4.5/5

Next up is the Sea Doo Dolphin, which is a personal dive submarine. It uses hands-on human control, not remote control (RC). It’s still worth a place in this guide as a very capable underwater craft.

• Best feature 1: GoPro Camera Mount
• Best feature 2: Excellent safety features
• Plus points: Lightweight design, easy to handle, good maximum depth, long runtime
• Minus points: Price, underpowered, long charging time

The Sea Doo Dolphin propels the operator above or below the water. It’s incredible fun for all the family, but especially the youngsters—under supervision. The newest version comes with a GoPro action camera mount so you can catch all the family fun and save it for posterity. It’s safe too. It sports a plethora of safety features like positive buoyancy, protective grilles, and auto cutoff.

The lightweight materials and careful design make it easy to handle with only a small learning curve. The Sea Doo Dolphin Personal Dive Submarine can reach a depth of 15 ft. The impressive 90 minutes runtime is another welcome feature. It’s still a good idea to invest in an extra battery and keep it fully charged if you’re out for the day.

The Not so Good

This personal dive submarine is not cheap at around 300 bucks (at the time of writing). It’s a great investment for anyone who spends lots of time in the water, though. Some folks—and especially older kids and adults—may find the maximum 2mph speed underwhelming after a while. The only other gripe is the long battery charging time. It’s an overnight job and possibly longer for the first charge.

5. PowerRay PowerSeeker Underwater Drone

Editor’s Rating: 4.6/5

My final pick is the PowerRayPowerSeekerWizard 4K submarine, though they call it an underwater drone. It’s a futuristic craft and light years ahead of the toy subs at the top of this page.

• Best feature 1: Powerful underwater photography and video craft
• Best feature 2: 4K UHD Video, 1080p real-time streaming
• Plus points: PowerSeeker, FPV, deep diving, 3 pilot modes, bright LED lights
• Minus points: High price

It’s a fishing drone because of its unique PowerSeeker and fish-finder mode, but it’s a lot more besides. The PowerRay is also a powerful underwater photography and video platform. Some of its many uses include treasure hunting, exploration, studying marine life, and mapping. You can even use it to record high-quality film projects with a little practice. It’s fun, flexible, and incredibly capable.

This amazing underwater robot comes with 4K UHD Video. There’s even 1080p real-time streaming so the captain can see what the camera sees—as it sees. It’s a different experience to other submarines where operators watch the vessel from above as it cruises underwater.

Seeing Is Believing

The PowerRay can go out of your line of sight (LOS) without you losing sight of it. The First Person View (FPV) capability means it becomes your eyes beneath the waves. It can go down as far as 98 feet, and that’s a long way for a small vessel. The three operating modes are low, medium, and high speed. These modes make it a great entry-level submarine with expert-level capability.

Unlike the other submarines on this page, this puppy is at home in the ocean. Its wide-angle lens ensures you capture plenty of close-up footage as the bright LED lighting illuminates the way. As with flying drones, this underwater craft also lets you view the world as you’ve never seen it before.

There’s so much going on with the PowerRay underwater drone that it really deserves a page of its own. Follow the link at the end of this review if you want to expand on the highlights above or discover all the features this remarkable product has to offer.

The Not so Good

The not so good has to be the price tag. This is a serious underwater vessel, and although it’s great fun, it’s not a toy. The price is fair for anyone who can put the product to work for him or her. It’s also a good price for those with a recreational budget to match. Alas, for most others the price makes it unobtainable or unjustifiable for what they need.
