Snorkelling and freediving have an awkward limit built into them. You can hold your breath, you can kick hard, but the distance you cover on a single surface interval is small — and the reef, the wreck or the drop-off you actually came to see is usually a little further out than your legs are willing to go. Families run into the same wall from a different direction: one person wants to swim out to the point, someone else is tired after twenty minutes, and the day ends earlier than anyone wanted.

Underwater scooters — also called sea scooters or DPVs — are the obvious answer, and Sublue has spent years building a range around exactly that problem. The brand sells everything from a $349 pool-and-beach toy to an eight-kilo jet-pump machine aimed at yacht tenders and serious open-water use, with several tiers in between. It is one of the few manufacturers that covers that entire spread under one roof.

In this Sublue review, we take a closer look at what the company actually sells, how the individual models differ on paper, what the official store charges, and — just as importantly — what the published shipping, returns and warranty terms commit Sublue to. Everything below comes from Sublue's own site, so you can check any figure yourself before you spend anything.

What Is Sublue?

Sublue describes itself as an underwater innovation company that pioneered the world's first portable recreational underwater scooter. According to its About page, the company operates from Los Angeles, Amsterdam, Tianjin and Shenzhen, and its engineering comes out of Deepinfar, a background in underwater robotics and marine engineering that Sublue says it uses to bring "professional underwater capabilities into everyday experiences."

The headline numbers Sublue publishes are 150,000+ units sold worldwide and a presence in 80+ countries and regions. The stated mission is to "bring people closer to the blue world, making every connection easier and more natural" — marketing language, certainly, but the product line does follow that logic, splitting into flagship, performance, family and play categories rather than chasing a single price point.

What Makes Sublue Different?

Three things stand out when you read across the full scooter collection.

• Genuine range coverage. Sublue sells scooters from $279 (open box) up to $4,099. Most competitors pick one tier and stay there.
• Two different propulsion philosophies. The Mix, MixPro, Navbow and Navbow+ use twin propellers. The VAPOR line uses a jet-pump with a six-blade impeller and twelve-blade rear guide vanes — a different engineering approach, not just a bigger version of the same thing.
• Serviceability. Batteries, chargers, propeller assemblies, motor front covers, battery covers and rotors are all sold individually. A $16 cover or a $51 propeller assembly is the difference between a repair and a write-off.

How a Sublue Underwater Scooter Works

The principle is straightforward: you hold the unit, squeeze a trigger, and a battery-powered motor pulls you through the water while you stay relaxed and breathe normally. What separates the tiers is how much thrust is on tap, how long the battery lasts, and how much information the device gives you.

Every handheld scooter in the current line-up is rated to 40 m (131 ft) except the entry-level SUBLUE EZ, which is rated 0–15 m (0–49 ft); the Swii, listed in the same collection, is a kickboard Sublue describes as a surface product for 0–1 m use. Most models use removable batteries, which matters for two reasons: you can carry a spare to double your day, and Sublue notes the battery specs are airline-compliant on several models. The EZ is the exception — its battery is built in and non-removable.

Entry-Level and Family Scooters: EZ, Mix and MixPro

SUBLUE EZ

At $349.00 the EZ is the cheapest way into the brand. It runs two speeds — 1.1 m/s (2.46 mph) low and 1.4 m/s (3.13 mph) high — from a built-in 92.88 Wh battery, giving 25 minutes continuous at low speed, 18 minutes at high speed, or up to 50 minutes of normal intermittent use. It weighs 3,500 g (7.72 lb) with the battery installed and charges in around 2.5 hours via a magnetic connector. The 0–15 m depth rating tells you the intent: pools, sheltered bays and snorkelling, not depth work.

Mix (2026)

The Mix is the model most people picture when they think of Sublue. The 2026 version runs dual motors at 1.2 or 1.6 m/s (2.68 / 3.58 mph), delivers up to 45 minutes of runtime from a removable 122 Wh battery, carries the full 40 m depth rating and weighs 3.5 kg (7.7 lb). Colours are Arctic White, Aqua Blue and Coral Pink.

MixPro (2026)

MixPro is the sensible upgrade rather than a different category. It adds a third speed — 1.2 / 1.5 / 1.8 m/s (2.68 / 3.36 / 4.03 mph) — and stretches runtime to up to 60 minutes from the same 122 Wh (11,000 mAh, 11.1 V) removable pack, with fast charging in up to two hours. It weighs 3.55 kg (7.82 lb) with battery, 2.66 kg without, and measures 465 × 230 × 230 mm. It ships with a removable floater, an action camera mount, a smartphone holder, an anti-lost safety leash and, on the 2026 model, a 30 L waterproof backpack. EU orders include two batteries; non-EU orders include one. Colours are White and Black.

Mid-Range Performance: Navbow and Navbow+

Navbow

The Navbow at $999.00 is where Sublue starts treating the scooter as an instrument rather than a toy. Three modes — Free 1.0 m/s, Sport 1.5 m/s, Turbo 2.0 m/s (2.24 / 3.36 / 4.47 mph) — run off a 420 W dual-motor system and a 158 Wh (10,670 mAh, 14.8 V) removable battery, for up to 60 minutes on a charge. It weighs 3.4 kg (7.49 lb) without the battery and measures 486 × 327 × 177 mm.

The details matter here: an OLED display, one-handed operation, micro-positive buoyancy so it floats rather than sinks if you let go, a vibration alert at 30% battery, a noise level Sublue rates at ≤60 dB, and two ¼"-20 mounting points plus a standard GoPro mount for cameras. Colours are Flame Red and Active Green.

Navbow+

At $1,199.00, Navbow+ shares the chassis, the 420 W motor rating (2,470 RPM max), the 158 Wh battery and the same three speeds, but upgrades the electronics. The OLED display shows depth, temperature, course and battery level, there is a digital compass, configurable dive alerts, and SublueGo app integration for dive logging. Sublue publishes mode-by-mode runtimes rather than one headline figure: roughly 45 minutes in Free, 20 in Sport, 8 in Turbo, or up to 60 minutes in normal mixed use. The battery alone weighs 1.1 kg. Colours are Phantom Gray and Flame Orange.

The Flagship: VAPOR and VAPOR Pro

VAPOR

The VAPOR from $2,999.00 is a different machine entirely. It abandons exposed propellers for a jet-pump using a six-blade impeller and twelve-blade rear guide vanes, producing 210 N of thrust — Sublue quotes a maximum of up to 21 kg. Three gears run at 6, 8 and 10 km/h (3.7 / 5.0 / 6.2 mph), with 45, 30 and 18 minutes respectively, or around 60 minutes typical mixed use, from a 384.8 Wh (13,000 mAh, 33.6 V) battery. Standard charging takes about three hours; fast charging cuts that to roughly 1.5 hours. It weighs 8.6 kg (19.0 lb) and measures 54 × 38 × 29 cm. Colours: Aventurine Red, Dravit Grey, Lighting Yellow and Aqua Blue.

VAPOR Pro

VAPOR Pro at $4,099.00 adds a fourth gear (12 km/h / 7.46 mph), raises thrust to 249 N (56 lbf), upgrades the display, ships with two 60-minute batteries for 120 minutes total, and charges in 1.5 hours. It weighs 8.7 kg (19.2 lb) and comes in Emerald Green and Azure Silver. Both VAPOR models keep the 40 m depth rating.

Accessories, Batteries and Other Sublue Products

The accessory catalogue is genuinely deep, and the spare-parts pricing is worth knowing before you buy:

• Spare batteries: Mix / MixPro $165.00; Navbow / Navbow+ $219.00; VAPOR / VAPOR Pro $749.00
• Fast chargers: Mix / MixPro $79.00; Navbow / Navbow+ / Swii from $89.00; VAPOR $299.00
• Wear parts: propeller assemblies $51.00 (Mix / MixPro), Navbow rotor $72.00, motor front covers and battery covers $13.00–$16.00
• Camera and phone rigs: photographic base plate $49.00, photographic connector $14.00, selfie extension stick $14.00, expandable phone clip kit $24.00, dual-ball butterfly clip $19.00
• Carry: 30 L waterproof backpack $99.00, 52 L $129.00, sport drawstring backpack $15.00

Beyond scooters, Sublue sells the H1 and H1+ smart waterproof phone cases ($99.00 and $139.00), a dive mask and snorkel set ($39.99), an anti-loss safety lanyard ($15.00) and the BN Pro Robotic Pool Cleaner at $1,099.00 (regular $1,399.00).

Sublue Pricing

Sublue's pricing ladder is unusually coherent. Roughly $350 gets you a shallow-water play scooter; $400–$700 gets a 40 m-rated family scooter with a removable battery; $1,000–$1,200 buys instrumentation, a compass, app logging and three speeds; $3,000–$4,100 buys jet-pump propulsion and real thrust. Each step up is tied to a specific, checkable spec change rather than branding alone.

Two things soften the cost. Several models were showing discounted pricing at the time of writing — the Mix from $399 against a $499 regular price (that is the Classic variant; the 2026 Mix is $449), MixPro at $699 against $729, EZ at $349 against $389, and the BN Pro cleaner $300 below list. And the Open Box listing starts at $279.00, with specific variants such as the Mix 2026 Arctic White at $359.00 and MixPro 2026 at $559.00 — a meaningful saving if the available colour happens to be one you want, since stock on that listing moves.

Shipping

Sublue ships from three hubs — California, Amsterdam and Tianjin — and the shipping policy is one of the more transparent ones you will find at this price point, because it publishes actual rate tiers instead of "calculated at checkout."

• United States: free over $100, otherwise $20. Approximately 2–7 days, shipped from California.
• Europe: free over €100, otherwise €20, approximately 2–7 days from Amsterdam. Remote areas: free over €200, otherwise €40, approximately 5–14 days.
• Rest of the Americas, Oceania and the Middle East: $100 up to $500 order value, $200 for $500–$1,000, $300 above $1,000. Approximately 7–25 days, duties and taxes included.
• Asia (Japan, Singapore, Thailand, Vietnam and others): $50 / $100 / $200 by order value, approximately 5–20 days.

Carriers listed are USPS, UPS, DHL, FedEx or local delivery partners. Sublue states that delivery times shown are estimates only and that multi-item orders may arrive in separate packages. Countries without a fixed rate need a custom quote by email.

Returns and Refunds

The refund policy gives you 30 days after delivery, but read the deductions carefully — this is the section most likely to surprise buyers.

For an unopened, unused product in original condition with all packaging, accessories and manual, Sublue deducts payment processing fees (2.5%+) and, where applicable, currency conversion fees (1.5%+). For products that were opened but unused, the deduction is 10%–50% of the order, determined by inspection. On U.S. orders Sublue prepays return shipping and deducts the cost from your refund; internationally it is deducted if Sublue pays, otherwise you cover it.

Items are not returnable if they have been used without a quality issue, fall outside the 30-day window, or are missing original packaging and accessories. Where the problem is a genuine quality defect, it is handled under warranty and Sublue covers return shipping on approved cases. Refund processing time is not specified in the published policy.

Warranty and SUBLUE CARE

The warranty page sets out coverage by product:

• Mix, MixPro, Navbow, Navbow+, Swii, Tini, Hagul EZ: 12 months on body and main controls, motion system, and battery and charger.
• VAPOR: 24 months on main unit and motor, 12 months on battery and charger.
• BN / BN Pro pool cleaner parts: 36 months. H1 / H1+ phone cases: 12 months.

Coverage applies to functional defects arising during normal use, including body, control boards, motors, propellers and power components. Excluded are cosmetic damage such as scratches and scuffs, accident or misuse damage, unauthorised repairs or modifications, and specified consumable parts. Claims go to support@sublue.com with order number, serial number, a description and photos or video. Replacements do not extend the warranty period, service fees of up to 20% may apply in some regions, and refunds are generally not offered under warranty unless local law requires it.

Sublue also sells SUBLUE CARE, an optional protection plan listed from $69.00, which adds one accidental-damage replacement, a 12-month extended warranty and 50% off an eligible battery replacement during the coverage period. Sublue notes that eligibility, service conditions and regional availability vary by product.

Customer Ratings Shown on the Official Store

Sublue displays review scores on individual product pages. At the time of writing, the VAPOR showed 4.9 out of 5 from 365 reviews, the Navbow 4.9 from 348, the MixPro 4.9 from 349, the Navbow+ 4.9 from 339, and the SUBLUE EZ 4.9 from 334. The newer VAPOR Pro showed 5.0 from a much smaller base of 18 reviews. These are the store's own on-site figures rather than independent ones, so weigh them accordingly — but the consistency across five separate products is at least notable.

Who Should Consider Sublue?

• Snorkellers and freedivers who want to cover more reef per session without burning their legs out — the Mix or MixPro is the natural fit.
• Underwater photographers and videographers, given the ¼"-20 and GoPro mounting points on the Navbow line and the dedicated base plates and clips in the accessory catalogue.
• Divers who want data — depth, temperature, course and a compass on the OLED, plus app-based dive logging on Navbow+.
• Yacht and boat owners who want a serious tender toy with real thrust: VAPOR and VAPOR Pro are built for that use case.
• Families and pool users on a budget, where the SUBLUE EZ at $349 and its 0–15 m rating are honestly matched to the job.

It is less suited to anyone who needs deep technical diving support — the whole range tops out at 40 m — or anyone unwilling to manage lithium batteries and post-saltwater rinsing as part of ownership.

Is Sublue Worth It?

On the evidence published on the official site, the value case is strongest in the middle. The MixPro at $699 gives you 60 minutes, three speeds, a 40 m rating, a removable battery, camera and phone mounts and a 30 L waterproof backpack in the box — that is a lot of capability for the money. The Navbow at $999 is the sweet spot for anyone who will actually use the instrumentation.

The VAPOR pair are a different proposition: $2,999 and $4,099 are yacht-toy money, and the jet-pump engineering, 210–249 N of thrust and the 24-month main-unit warranty Sublue publishes for the VAPOR are what you are paying for. Whether that is "worth it" depends entirely on whether you have the boat, the storage and the water to justify 8.6 kg of scooter.

The two things to go in with your eyes open about are the return deductions — 10%–50% on an opened-but-unused unit is steep — and the 12-month battery warranty across most of the line, on a device where the battery is the expensive consumable ($165 to $749 depending on model). SUBLUE CARE exists specifically to blunt both, which tells you something.

Final Verdict

Sublue is a serious, well-documented operation rather than a drop-shipped gadget brand. The official store publishes real specs, real rate tables, a written warranty schedule broken out by product, and a spare-parts catalogue that assumes you will own the thing for years. That combination is rarer than it should be in this category.

The range is coherent from $349 to $4,099, the 40 m depth rating is consistent across everything except the entry-level EZ and the surface-use Swii, and shipping is free over $100 in the US and over €100 in Europe with 2–7 day estimates from local hubs. The caveats are the return-deduction structure and the 12-month battery cover, both of which are disclosed clearly enough that you can price them into your decision.

If you snorkel, freedive or shoot underwater and have been frustrated by how little water you can cover in a session, Sublue's mid-range models are a genuinely strong answer. If you are outfitting a boat and the budget is there, the VAPOR line is the flagship for a reason. Either way, read the shipping and refund pages before you check out.
