SUBLUE Underwater Scooters: How to Pick the Right Model

SUBLUE sells four handheld underwater scooters, and at first glance the range can blur together. The model names sound alike, the depth rating is identical, and the real differences sit in battery size, runtime, speed and weight.

This guide sorts the range out. It covers the brand’s background, how the Mix, MixPro, Navbow and Vapor differ, what the numbers mean in the water, how SUBLUE lines up against Yamaha and Seabob, and what to know about returns, warranty and care.

Everything here rests on the brand’s published specs and policies, not on hands-on testing. Where SUBLUE makes a claim, the text says so. Where a fact is missing, the guide leaves it out.

Where SUBLUE Comes From

SUBLUE is the consumer label of Deepinfar Ocean Technology, a company set up in 2013 to build underwater robots for professional and industrial clients. The SUBLUE name followed in 2016 as the arm that sells to consumers.

Four bases are named: Los Angeles, Amsterdam, Tianjin and Shenzhen. Together they give the brand a footprint in large consumer markets and keep its original manufacturing roots in the picture. Its stated philosophy is to let the technology fade into the background while the experience stays in front.

What the brand says about itself

The figures below are SUBLUE’s own claims, so treat them as marketing until you have checked them yourself.

• The company states that it holds over 400 technical patents.
• It presents itself as the pioneer of the first portable dual-propeller underwater scooter.
• It reports more than 200,000 scooters sold since 2013, across over 80 countries.
• It asserts a share of about 65% of the worldwide underwater scooter market.

SUBLUE also says its 100,000th scooter was sold by 2022. Set against the 200,000 total, that would mean the second 100,000 went out faster than the first.

Design recognition by model

The brand lists design awards spread across several product generations.

The first Mix arrived in 2017, and its design language still shapes the Mix line. The Vapor joined later as the flagship. Awards say nothing about how a scooter behaves in real water, but a run of them over several generations hints that the engineering team has kept developing the range.

The Four Models at a Glance

All four models carry the same depth rating, 40 meters (131 feet), so the real differences are battery size, runtime, speed and weight.

Read the table as a ladder. The Mix and MixPro share a compact body and a 122 Wh pack. The Navbow moves up to two motors and a 158 Wh pack. The Vapor sits in a different class, with a 384.8 Wh battery and a weight of 8.6 kg.

Mix

This is the entry-level scooter, with two speed modes and a build aimed at pool days and light snorkeling. At 3.5 kg with its battery fitted, it is the lightest model in the range. A full charge takes up to four hours on the standard charger, or about two hours with the fast charger that is sold separately.

MixPro

The MixPro keeps the Mix’s body and 122 Wh pack, then adds a third speed mode and up to an hour of runtime. A full charge takes about two hours. Newer versions include a 30L waterproof backpack, so confirm what ships with the version you choose.

Navbow

Two motors, a 158 Wh pack and a 2 m/s top speed, the highest of the three smaller scooters. SUBLUE positions it as its recreational powerhouse.

Vapor

The flagship offers three gears, a 384.8 Wh battery and thrust listed at up to 21 kg. Runtime drops to 18 minutes at full power. The brand presents it as marine equipment rather than a beach toy, pitched at divers and boat owners who want the strongest pull in the range.

What the Specs Mean in the Water

Speed

Top speeds look modest on paper. On the Mix, MixPro and Navbow, each speed mode has its own cap, and the highest mode sets the number in the table. The Vapor works in three gears and peaks at 10 km/h (6.2 mph).

Battery capacity and runtime

Capacity is quoted in watt-hours, the energy stored in the pack. More watt-hours give the motors more to work with, but the speed you run decides how quickly that energy drains. The Vapor shows this clearly. Its runtime shrinks sharply at the top gear, so a big battery does not guarantee a long session.

Depth rating

Because the whole range carries one rating, depth will not help you pick. Speed, battery and weight do the deciding.

Weight and thrust

Weight counts before you reach the water, since you carry the scooter from the car to the shoreline, onto a boat or into a pool. The Mix and MixPro are the lighter pair. Thrust is the pulling force the motors produce, and the Vapor lists the highest figure in the range.

Matching a Model to How You Swim

Base the choice on the water you visit regularly, not on a dream trip. This table pairs each main use with the model that fits it on paper.

A backyard pool rarely calls for the Navbow’s power or the Vapor’s size. If you are unsure which tier to buy, the Navbow sits in the middle of the range, and our full verdict on the SUBLUE Navbow goes through it in detail.

Questions to settle before you buy

• How long are your sessions? Runtime runs from 45 minutes on the Mix to 60 on the MixPro and Navbow, and the Vapor falls to 18 minutes at full power.
• Who will carry and steer it? The Mix and MixPro are the lighter pair, while the Vapor weighs 8.6 kg.
• Which extras do you want in the box? The Navbow includes a charging stand, buoyancy bar, one-hand lanyard and safety leash.
• Where will you buy it? The warranty depends on a legitimate seller and proof of purchase, and later sections cover both.

SUBLUE Against Yamaha and Seabob

Yamaha also builds underwater scooters, and its Seascooter range makes a useful yardstick for specs. This table sets the Navbow beside the Yamaha 350Li Seascooter.

Yamaha leads on runtime, SUBLUE leads narrowly on speed and depth is level. If long sessions matter more than anything else, Yamaha deserves a look.

The approaches differ too. SUBLUE builds handheld dive propulsion units that pull you along while you hold them out in front of you. Yamaha covers a wider spread, from simple surface scooters for younger riders to more advanced dive models. SUBLUE’s pitch is a tighter range in which every model shares one core design, and it publishes its warranty terms openly.

At the premium end, the Vapor is compared with Seabob, a German luxury brand associated with yachts. SUBLUE aims its flagship at anyone after a powerful pull and a look that suits a yacht.

Accessories Worth a Look

SUBLUE’s catalog goes beyond scooters. Three accessories are worth knowing about.

• Waterproof backpack, 30L: carries the scooter and your gear to the water and keeps everything dry on the way. Newer MixPro versions include one, so it matters mainly to owners of older MixPro units and to Navbow riders.
• Anti-loss safety lanyard: a small open-water add-on that keeps a moving scooter tied to you.
• Navbow and Navbow+ accessory kit: a bundle for current Navbow owners that collects extras into a single purchase.

Before adding anything, list what you already own, so you buy only what is missing.

Buying From a Legitimate Seller

Gray-market resellers and counterfeits circulate in this category, so the seller matters as much as the model. SUBLUE runs its own store, where you deal directly with brand support if something goes wrong.

Other retailers carry the range too, including Best Buy, West Marine, Adorama and the dive specialist Diversdirect. The brand also has a storefront on Amazon, and you can browse SUBLUE’s storefront on Amazon, which opens Amazon in a new tab, and set what it lists against this guide.

Warning signs of a fake listing

• A bargain with no stated reason, such as open-box stock, clearance or a retired color.
• A seller who goes vague on serial numbers or warranty registration, even though genuine units come with paperwork you can register.
• A seller who cannot say which battery capacity or model year is in the box. The brand revises batteries and included accessories from year to year, so a legitimate seller knows which version ships.
• No return policy, or a shipping origin nobody will name.

Coverage depends on a legitimate channel and proof of purchase, so a small saving from a doubtful seller can leave you with no recourse if the battery fails.

Returns, Warranty and Support

These terms come from SUBLUE’s own policy pages. A retailer’s return terms may differ, so read those as well.

Warranty

Both terms need proof of purchase. Faults that stop the device from working properly are covered, while scuffs and scratches from everyday use are not. A shorter term for the battery is common, because packs wear faster than the rest of the unit.

A claim usually ends in an exchange rather than a refund, unless SUBLUE has no replacement to send. To open one, email photos of the problem to [email protected]. Keep your receipt somewhere safe, because returns and warranty claims both depend on it.

Returns

Returns are accepted for 30 days from the purchase date. Opening the product triggers a 30% restocking fee, which some regions waive when the product itself is faulty. Approved refunds reach your original payment method within 10 to 15 business days.

Because of that fee, plan a pool session early in the 30-day window. You will learn whether the scooter suits you before committing to an open-water outing.

Care That Keeps It Running

A scooter that fails after one season because nobody rinsed it is an avoidable disappointment. The routine is simple, but it only works if it happens every time.

Salt, sand and moisture

After saltwater, rinse the whole unit with fresh water, because salt can wear down seals and moving parts. Look over the propeller area for sand, seaweed and small stones, which can strain the motor. Let everything dry fully before it goes into a bag. A waterproof backpack is the better way to travel, since a wet scooter in an ordinary bag can stress the housing seals and soak your other gear.

The battery

SUBLUE rates its scooters for temperatures from 0 to 35°C (32 to 95°F), so a hot car is a poor storage spot. Lithium packs generally last longer when you recharge before they hit empty, and for a long break they do better stored partly charged than empty or full.

If the battery cover looks swollen or misshapen, treat it as a warning sign. Stop using the pack and contact SUBLUE support.

Paperwork

Register the warranty soon after purchase, and keep proof of purchase where you can find it. Both warranty terms depend on it, so do not wait until something breaks.

Frequently Asked Questions

Which model suits a first-time buyer?

For pool or lake use alone, the Mix covers it. If you are unsure, the Navbow sits between the entry models and the flagship, with two motors and a 158 Wh pack. To look over the range, browse SUBLUE’s storefront on Amazon and compare each model’s contents with the specs in this guide.

How deep are these scooters rated?

SUBLUE gives every model in the range a 40-meter (131-foot) rating.

How long does a charge last, and how long to refill it?

The Mix, MixPro and Navbow list between 45 and 60 minutes, while the Vapor varies by gear and falls to 18 minutes at full power. A MixPro refills in about two hours. A Mix needs up to four hours on the standard charger, or about two with the separately sold fast charger.

Is the app required?

Basic operation works without it, but certain functions depend on the companion app. Set it up early, so you know what it unlocks before the 30-day return window closes.

Can I use one in the ocean?

The brand builds these scooters for ocean use. Wash the unit and the battery contacts with fresh water afterward, since salt left behind can lead to corrosion.

What ships in the box?

Every scooter comes with its own battery, a charger and a safety leash. The Navbow also brings a charging stand, plus a buoyancy bar and a D-ring buckle. Newer MixPro versions add a 30L waterproof backpack.

How heavy are they?

The Mix and MixPro weigh 3.5 and 3.55 kg with the battery fitted. The Navbow weighs 3.4 kg without its battery, and the pack adds 1.1 kg. The Vapor is far heavier at 8.6 kg (about 19 lb).

How can I tell a unit is genuine?

Buy from SUBLUE’s own store or a legitimate retailer, and check the listing against the warning signs above.

What if the battery has a problem?

Email SUBLUE support with photos of the fault. A functional defect falls under the six-month battery warranty, while ordinary cosmetic wear does not.
