Meet Your Next Dive Buddy: An Honest Look at the Sublue Whiteshark Mix Pro
If you've ever spent an hour fighting a headcurrent while snorkeling over a reef, you know how quickly fatigue can ruin a great dive day. That's where the Sublue Whiteshark Mix Pro comes in. Designed primarily as a compact, travel-friendly underwater scooter (also called a diver propulsion vehicle or DPV), the MixPro is built for recreational divers, snorkelers, and backyard pool enthusiasts who want to glide through the water without exhausting themselves. Its standout benefit is a dual-propeller propulsion system packed into a chassis light enough to fit inside a backpack, alongside a battery that you can legally carry onto a commercial airplane. If you want to cover more reef on a single breath or protect your camera rig from shaky, tired hands, this model is absolutely worth your consideration. Let's break down exactly what it's like to live and dive with this machine.
To help you visualize this underwater scooter in action, take a look at the unit ready for deployment below:
As a veteran diver, I've seen DPVs evolve from massive, heavy metal cylinders used exclusively by cave divers into the lightweight, battery-powered recreational tools we see today. The MixPro represents a sweet spot in this evolution. It balances portable design with enough power to make a noticeable difference in your dive profile. It doesn't aim to pull a commercial diver loaded with 100 pounds of gear through a raging current, but for exploring shallow reefs, keeping up with sea turtles, or taking the physical strain out of snorkeling, it's an incredibly capable companion.
---Unboxing the MixPro: What's in the Box?
When you first open the packaging, you'll notice how cleanly organized the kit is. Sublue didn't just throw the scooter in a cardboard box; they provided a complete ecosystem designed for immediate use. Inside, you'll find:
- The Sublue Whiteshark Mix Pro main unit
- A detachable buoyancy float (essential for surface snorkeling)
- A fast-charging power adapter and power cable
- A 122Wh Lithium-ion battery pack
- A safety leash to keep the scooter attached to your wrist
- A dual-trigger guard accessory (for younger or less experienced users)
- An action camera mount adapter
- A waterproof smartphone holder mount
- User documentation and safety guides
The build quality feels solid right out of the gate. The outer casing uses a dense, impact-resistant polycarbonate blend that can handle the occasional bump against a pool wall or a sandy beach landing. The dual thrusters are fully enclosed within protective grilles, a critical safety feature that prevents stray fingers, seaweed, or hair from getting caught in the fast-spinning propellers.
---Technical Specifications and Performance Metrics
To truly understand how this scooter behaves underwater, we have to look closely at the numbers. Sublue provides specific technical data that governs the speed, depth, and duration of your dives. Let's look at the core specifications of the MixPro:
| Specification | Metric Value | Imperial Value |
|---|---|---|
| Dimensions | 465 x 230 x 230 mm | 18.3 x 9 x 9 inches |
| Weight (with battery & float) | 3.55 kg | 7.8 lbs |
| Battery Capacity | 122 Wh (Lithium-ion) | 122 Wh (FAA Compliant) |
| Low-Speed Setting | 1.2 m/s | 2.68 mph (2.3 knots) |
| High-Speed Setting | 1.8 m/s | 4.03 mph (3.5 knots) |
| Maximum Depth Rating | 40 meters | 131 feet |
| Runtime (Variable) | Up to 60 minutes | Up to 60 minutes |
| Charging Time | ~2 hours | ~2 hours |
Understanding these figures requires contextualizing how they apply in real water environments. The 1.8 meters per second high-speed setting might not sound incredibly fast when compared to walking or running on dry land, but in water, it's quick. To put it in perspective, Olympic swimmer Michael Phelps swims at an average speed of about 2.1 meters per second during a 200-meter freestyle. With the MixPro, you're gliding through the water at a pace close to an Olympic sprinter without moving a muscle. This reduces oxygen consumption, lowers your heart rate, and vastly extends your bottom time when skin diving or snorkeling.
---Deep-Dive: How the Dual-Propeller System Works
Most traditional entry-level underwater scooters use a single central propeller. While this design is cheaper to manufacture, it introduces a physical phenomenon called rotational torque. When a single propeller spins rapidly, it exerts a twisting force on your wrists, forcing you to constantly exert effort just to keep the scooter pointing straight. Over a 45-minute dive, this torque can cause significant forearm fatigue.
The MixPro bypasses this issue entirely by utilizing a dual-propeller setup. The two motors are spaced widely on either side of the main body, spinning in opposite directions (counter-rotating). This design cancels out rotational torque, allowing the scooter to track straight forward with zero effort from the diver. You can literally hold the MixPro with one hand (though for safety, both hands are recommended) and it will pull you in a straight line without pulling to the left or right.
A Close-Up View of the Dual-Thruster Layout
To see how the dual-thruster design integrates with the camera mounts and battery housing, look at the front profile of the scooter below:
This symmetry doesn't just help with tracking; it also provides safety redundencies. If a plastic bag or piece of kelp somehow manages to wrap around one propeller and trigger a safety shutdown, the other thruster won't violently spin you in circles. The onboard microcontrollers monitor the electrical draw of each motor and will shut down power if they detect a stall or motor imbalance, preserving the integrity of the electronics and protecting your hands from potential injury.
---The Detachable Buoyancy Float: Practical Buoyancy Control
One of the most practical design decisions in the MixPro is the inclusion of the detachable top-mounted buoyancy float. In the world of diving, managing buoyancy is everything. If you drop your gear in deep water, you want to know exactly what's going to happen next.
With the Floatation Mount Attached
With the float attached, the MixPro becomes slightly positive. If you let go of the triggers while snorkeling or swimming at the surface, the scooter will slowly bob up to the surface and float there. This is a crucial safety net for children, casual pool users, and snorkelers. If a cramp hits or you drop the scooter to clear your mask, you won't have to watch your expensive investment sink into the abyss.
Without the Floatation Mount
If you are a recreational scuba diver or a freediver aiming to dive down to 20 or 30 meters, you must remove the buoyancy float. To do this, you simply depress two locking clips and slide the float off the top of the body. Without the float, the scooter becomes slightly negatively buoyant in salt water. This means when you release the triggers, the unit will slowly sink rather than floating back to the surface.
Why is this positive? If you're hovering at 15 meters looking at a nudibranch, you don't want your scooter constantly trying to pull you toward the surface like a balloon. A slightly negative buoyancy profile makes it easy to park the scooter on a sandy patch or let it hang from its safety leash around your wrist while you adjust your camera or check your dive computer.
---Battery Mechanics, Air Travel Compliance, and Charging
The battery is the heart of any electric DPV, and it's also where many other travel scooters fail to deliver. High-capacity lithium batteries are strictly regulated by aviation security agencies like the FAA (Federal Aviation Administration) and TSA due to thermal runaway risks. The general rule for passenger aircraft is that any lithium-ion battery with a capacity exceeding 160 Watt-hours (Wh) is strictly banned from passenger flights.
Sublue engineers carefully designed the MixPro battery pack to sit at exactly **122 Watt-hours**. This means the battery is fully compliant with commercial airline regulations as carry-on baggage. You cannot pack the battery in your checked luggage, but you can safely carry it with you in your cabin backpack. This is an immense benefit for divers who travel to remote tropical destinations like Cozumel, Bonaire, or the Maldives. You don't have to deal with complex hazmat shipping paperwork or try to rent a sketchy battery at your destination.
Real-World Battery Run Times
Sublue advertises a battery runtime of up to 60 minutes. It's important to understand how that 60-minute figure is calculated. If you lock the scooter on high-speed mode (1.8 m/s) and hold down the triggers continuously while dragging a fully geared-up scuba diver wearing a thick wetsuit, the battery will deplete in about **20 to 25 minutes**. This is because drag increases exponentially with speed, and pulling a large body through water requires significant current draw from the lithium-ion cells.
However, if you use the low-speed setting (1.2 m/s) and use pulsed bursts of speed rather than holding the trigger down continuously (which is how most snorkelers and divers actually use these devices), you can easily stretch the battery life to **45 to 60 minutes**. If you are planning a full day of diving, I highly recommend purchasing a spare battery pack so you can swap them out between surface intervals.
Understanding the Charging System
The MixPro comes with an updated fast charger that connects directly to the proprietary gold-plated pins on the battery pack. Charging a fully depleted battery back to 100% takes roughly two hours. To ensure the longest possible lifespan for your lithium battery, follow these three rules:
- Let the battery cool down before charging: When you pull the battery out of the scooter after a long run, it will feel warm. Do not plug it into the charger immediately. Let it rest in a cool, shaded spot for 15 minutes to prevent heat buildup during the fast-charge cycle.
- Never store a dead battery: If you drain the battery to 0% and leave it in your gear bag for three months, the voltage can drop below the threshold where the battery management system (BMS) can recover it. Always charge the battery to about 50-60% capacity before long-term storage.
- Keep the contacts clean: Before mounting the battery into the scooter or onto the charger, inspect the gold-plated pins. If you see salt crust or water droplets, wipe them clean with a dry microfiber cloth and some fresh water or isopropyl alcohol.
Ergonomics, Dual Triggers, and Camera Mounts
Driving the MixPro is simple. The hand grips are positioned at a natural angle that mimics the neutral resting position of your wrists when swimming. On each grip, there is a trigger button. To activate the motors, you must press **both triggers simultaneously**.
This dual-trigger design is an essential safety feature. If you drop the scooter or let go with one hand to adjust your diving mask, the motors instantly cut out. This prevents runaway scooters from zooming away from their operators and colliding with marine life or other divers. If you want to change speed settings, you simply double-click either trigger while keeping the other one depressed. An LED screen sits right in the center of the scooter, letting you quickly verify your current speed setting (one light for low, two lights for high) and the remaining battery percentage.
For those interested in capturing their dives, the built-in action camera mount is positioned directly on the front nose of the scooter. This allows you to mount a GoPro or similar action camera. Because the counter-rotating propellers keep the scooter exceptionally stable, the footage you capture with the MixPro is remarkably smooth, lacking the constant side-to-side wobble that often occurs when hand-holding an underwater camera while swimming.
---Real-World Testing: Pool, Beach, and Reef Scenarios
To give you a realistic expectation of how the MixPro performs, let's look at how it behaves in three distinct water environments:
1. The Backyard Pool (Family and Recreation)
In a controlled pool environment, the MixPro is exceptionally fun. It's quiet, easy to maneuver, and small enough that it doesn't crowd a standard swimming pool. Children can easily use it when the buoyancy float is attached, allowing them to glide along the pool floor or swim laps without becoming exhausted. The protective grilles around the propellers ensure that fingers, toes, and hair remain safely isolated from the moving blades.
2. The Sandy Beach Entry (Snorkeling and Shore Diving)
Using the MixPro for a beach entry requires a bit of care. When walking through the surf zone, keep the scooter turned off and held securely by the top handle. Sand is the enemy of any underwater thruster. If waves kick up fine sand and wash it into the propeller cowlings, it can get trapped between the propeller shaft and the housing, causing friction and eventual motor lockup. Once you swim out past the breaking waves and reach clear water, you can safely turn the scooter on and begin diving. Here, the scooter excels by helping you get out to offshore reefs that would normally require a long, tiring swim.
3. The Open Ocean Reef (Scuba Diving and Freediving)
On an open ocean reef, the lack of wrist torque makes navigating around coral heads simple. You can steer the scooter with subtle movements of your shoulders and hips, carving through the water with precision. If you're a freediver, the MixPro allows you to save your precious oxygen supply on descent. Instead of performing a high-effort kick cycle to get past your positive buoyancy zone, you can let the scooter pull you down smoothly, allowing you to maximize your bottom time at depth.
---What the Community Says: Reddit and Trustpilot Insights
When purchasing underwater equipment, it's vital to look beyond marketing brochures and examine real-world user feedback. We've combed through active discussions on Reddit and customer reviews to see how the MixPro holds up over months of real use.
In a prominent Reddit discussion on r/DivingGearReview, users highlighted that while the scooter is incredibly fun and lightweight, understanding battery management is crucial. Several Redditors noted that running the scooter continuously at full speed drains the battery quickly, which is a common trade-off for any ultra-portable DPV. Experienced divers in the thread recommend using pulsed trigger pulls to cruise at a more efficient speed, allowing you to get the most out of every dive session.
Looking at broader brand reputation, Sublue maintains an active presence online. You can view their customer satisfaction ratings on Trustpilot. To give you an idea of how users evaluate their customer service and build quality, here is a screenshot of their brand review feedback:
Common praise focuses on the compact size, the ease of air travel, and how much fun it adds to family vacation trips. The minor complaints usually stem from users who expected commercial-grade battery life (2+ hours of continuous run time) from a lightweight travel battery, emphasizing the importance of setting realistic expectations based on the laws of physics and battery limits.

Comparison: MixPro vs. Original Whiteshark Mix
If you're researching the MixPro, you've likely noticed its predecessor, the original Whiteshark Mix. While they look similar at first glance, the Pro model introduces several key refinements that address limitations of the original design:
- Dual-Speed Selection: The original Whiteshark Mix had only a single speed setting (1.5 m/s). The MixPro offers two distinct speeds (1.2 m/s and 1.8 m/s), giving you better control over battery consumption and underwater pacing.
- Fast Charging Standard: The original model took up to 4 hours to charge. The Pro comes standard with a fast charger that reduces charge times down to approximately 2 hours.
- Improved Battery Life: Thanks to more efficient electronic speed controllers (ESCs) and battery chemistry refinements, the Pro model extends average runtimes by about 10 to 15% compared to the original under identical conditions.
- Smartphone Mount: The MixPro includes a mounting bracket that accommodates a waterproof smartphone case, allowing you to use your phone as an underwater camera if you don't own an action camera.
Maintenance and Longevity: Keeping Your Scooter Alive
Water, especially salt water, is an incredibly hostile environment for mechanical and electrical systems. If you want your MixPro to last for years instead of months, you must establish a strict post-dive maintenance routine. This isn't just friendly advice; it is standard protocol outlined in the Sublue official manual.
The Post-Dive Rinse Routine
Every single time you take the scooter out of the ocean or a chlorinated pool, you must perform these steps:
- Fresh Water Soak: Submerge the entire unit (with the battery securely installed to protect the internal pins) in a tub of clean, warm fresh water for at least 15 to 20 minutes. This allows salt crystals and pool chemicals to dissolve.
- Trigger Clean: While the unit is submerged in fresh water, press the triggers repeatedly to clear out any sand grains, silt, or salt deposits that may have gathered inside the trigger spring mechanisms.
- Dry and Disassemble: Take the scooter out of the water and dry the exterior with a clean towel. Remove the battery pack and inspect the battery compartment. If you see any droplets of water near the seal, dry them immediately.
- Propeller Inspection: Manually spin the propellers to ensure they rotate freely without any grinding noises or resistance. If you feel resistance, check for hair, fishing line, or seaweed wrapped around the propeller shafts.
Never leave your scooter baking in the hot sun on a boat deck. High temperatures can degrade the seals, weaken the plastic housing, and cause the lithium-ion battery cells to swell or degrade prematurely.

For travelers, casual divers, and families looking to maximize their aquatic adventures, it represents a fantastic balance of value, portability, and performance.
---Frequently Asked Questions About the MixPro
Is the Sublue Whiteshark Mix Pro suitable for deep scuba diving?
Yes. The MixPro has an official maximum depth rating of 40 meters (131 feet). This matches the limit of recreational diving. Remember to remove the detachable top buoyancy float before diving down so that the scooter achieves a slightly negative buoyancy profile. This prevents it from fighting against you as you maintain your depth.
Can I travel with the MixPro battery on a passenger plane?
Yes, you can. The battery has a rated capacity of 122Wh, which is well within the FAA and TSA limits of 160Wh for passenger carry-on bags. You must packed the battery inside your carry-on luggage. Never put it inside your checked baggage, as aviation safety guidelines forbid lithium batteries in cargo holds.
What happens if I release the triggers while underwater?
The scooter features an instant safety cutoff. As soon as you release even one of the triggers, the motors will shut down immediately. If you have the buoyancy float attached, the scooter will slowly rise to the surface. If the float is removed, the scooter will slowly sink to the bottom. For safety, always wear the included wrist leash so the device doesn't drift away from you.
How long does the battery take to charge?
Thanks to the improved fast charger included in the MixPro kit, a fully depleted battery takes approximately 2 hours to reach a 100% charge. It is highly recommended to let the battery cool down for 15 minutes after a dive before connecting it to the charger.
Can children use the Sublue MixPro safely?
Yes, the MixPro is highly accessible for younger users. The propellers are fully shielded by plastic protective grilles on both ends, preventing accidental contact. However, children should always use the scooter under direct adult supervision and keep the buoyancy float attached to prevent the scooter from sinking.
How do I switch between the low-speed and high-speed modes?
The MixPro utilizes a simple trigger shortcut. While holding down both triggers to run the scooter, double-click either trigger. The scooter will switch between its low-speed (1.2 m/s) and high-speed (1.8 m/s) settings. The LED indicator panel in the center of the unit will change to reflect your active speed setting.
What is the difference between the original Whiteshark Mix and the Mix Pro?
The Mix Pro adds a second, faster speed mode (1.8 m/s), cuts charging time in half with a new fast charger, has a built-in battery indicator LED screen, and includes a specialized mount to secure a waterproof smartphone case directly to the scooter's frame.
Can salt water damage the motors of the scooter?
The motors are fully sealed and designed to work in marine environments, but salt water will form corrosive crystals if left to dry inside the housing. Always soak the entire unit in fresh water for 15 to 20 minutes after every ocean dive, and activate the triggers while submerged to flush out any trapped salt or sand.
