Technical Specs / Sizing Charts
More innovative and a better engineered design
The Genesis DPV was created because the DPV offerings on the market were unimpressive to someone with real industrial subsea experience. The "high performance" scooters of the day were based on the same technology as pool toys with only minor improvements. This was not acceptable to a subsea engineer......and so the Genesis project was born!
Take a ride on a Genesis scooter!

The advantages of the Genesis scooters are a combination of innovative design and proper engineering. So let's start at the nose and work back!
External recharge connector
- Rated for 10,000 PSI, it is the first of many features in the design that are best described as overkill. There is no power at the pins when the charger is not installed so the pins will not short out if the cover is left off when put in the water or removed underwater. Additionally, if the cover is not installed, the motor controller will not be enabled to run, increasing safety and stopping the quiescent power drain from the batteries.
- By not opening the scooter body to recharge the batteries, the risk of seal damage and wear on the battery connectors from repeated unmating and mating is reduced. Additionally by not repeatedly opening the body, humidity is not allowed in to condense when the colder scooter is opened in a warmer, humid environment.
Pressure and vacuum test port
- Can also be used to vent pressure differentials from altitude changes. The Genesis body can be tested for both vacuum and pressure since there is no shaft seal to vent out or spring latches to stretch open during pressure testing. Standard SAE -4 port (same as a high pressure port on a regulator).
- There is no need to spend hundreds of dollars on an extra tool for testing and should a leak occur, its location can be quickly determined with a bubble test under pressure.
Plastic bumper on nose
- Prevents damage to anodizing when placed nose down in tank racks on the boat ride out or when stood on the nose to remove the tail.
- Better protection of corrosion control finish.
Hard anodized 6061 aluminum body
- No welds and no stainless steel. Welding heat treated aluminum reduces its strength to almost half in the heat affected zone. Having stainless steel fastened to aluminum causes galvanic corrosion due to dissimilar metals and crevice corrosion in treaded holes.
- Stronger and much less prone to corrosion.
Proper O-ring grooves
- Two o-rings (same size) provide redundancy at the body to tail connection. The grooves follow industrial standard dimensions to prevent over-compression that results in damage to the o-ring and premature failure. Other designs that clamp an o-ring between two flat faces or wedge it into a corner with a simple chamfer can quickly damage a seal when that o-ring has to react the entire crushing force between the body and tail at depth.
- Longer seal life and reduced possibility of seal failure.
Sealed battery housings
- Can be easily removed and are still watertight when out of the DPV. The center of mass of the assembled battery pack is off center from the DPV central axis, providing counter torque to reduce diver effort. Additional room is available to install trim weights as far from the center line as possible.
- Humidity can not enter battery assembly, causing corrosion and battery weight distribution reduces divers effort to counteract motor torque.
Highly integrated tail section
- The Genesis motor is shrink-fit into the aluminum tail cone, providing the most direct path to dump heat from the motor to the water. The motor controller is also heat sunk to the tail cone and the Genesis can be run at full power continuously, even beyond the capacity of the 1200Wh battery, without overheating. Every scooter is burn tested, non-stop at full power for one full battery cycle before shipping. The magnetic coupling eliminates the dynamic shaft seal, which is the most likely failure point on every other DPV currently available. Due to the magnetic coupling the motor bearings never experience axial loading and do not require replacement on a regular basis. The bearings for the propeller shaft are full ceramic with a 10,000 hour design life and the ceramic material is harder than almost any particles that may get in them, including sand. Additionally, the intelligent motor controller monitors battery voltage and will limit the power to 50% when the battery is at the last 15-20 percent of its capacity. (50% is still more thrust than most scooters are even capable of)
- More efficient and reliable design, eliminating the major leak point and requiring less maintenance. Propeller can be removed in seconds and without tools to clear ingested fishing or spool line.
Fully engineered propeller and nozzle design
- The nozzle, propeller and motor were engineered to work together as a system for maximum efficiency. A nozzle needs to be more than just a funnel for water flow and protection from the rotating blades. The Genesis nozzle provides thrust, just like an airplane wing provides lift. At full power static thrust, about 35% of the total thrust is generated solely by the pressure differential from the outside to the inside of the nozzle. The streamlined design avoids turbulence that reduces thrust and causes the flow out the back of the nozzle to rapidly disperse. The result is higher thrust at a given power and a flow column that stays consolidated longer enabling the DPV to be operated closer to silty bottoms or cave walls without disturbing them and reducing visibility. The nozzle is a foam material that adds buoyancy to the tail section, so that the body can be shorter and the nozzle outer diameter is 1.15 inches smaller, making a more compact DPV. The Genesis 600 can be fitted into a single shipping case that meets normal airline baggage restriction.
- More efficient power conversion and less likely to disturb silt in a cave. Smaller overall size to fit through tight openings and easier to transport on passenger aircraft.
One hand operation of all controls
- The ON-OFF trigger, trigger lock and speed control can all be operated with a single hand. The trigger can be easily locked OFF for safety or locked ON for long cruises with a flick of the finger. The variable speed lever is easily operated with the thumb on the fly instead of having to reach for an adjusting knob on the body.
- Easier to operate.
Infinitely variable speed control
- Any speed can be set and the motor will gently accelerate up to that speed instead of jerking the diver when the trigger is pulled. The speed can be adjusted from zero to 100% while moving and there is a sufficient dead band at zero speed that acts as a second safety to locking the trigger OFF. No missed shifts or multiple clicks to get to the speed you want and it is easy to dial in the exact same speed as your dive buddy.
- Easier on the diver at start-up and more controllable with redundant safety features.
More innovative and a better engineered design.
The Genesis DPV was created because the DPV offerings on the market were unimpressive to someone with real industrial subsea experience. The "high performance" scooters of the day were based on the same technology as pool toys with only minor improvements. This was not acceptable to a subsea engineer...
...and so the Genesis project was born!
First and foremost, high speed shaft seals, whether they are on a thruster or subsea pump, are the bane of anyone who has to work on them and a constant source of maintenance or failure. The magnetic coupling removes the dynamic seal issues and also enables the propeller to be easily removed should line get ingested and wrapped around the prop. Additionally, it acts as the decoupling clutch should the prop become jammed.
A variable speed motor and fixed blade propeller is the most efficient configuration for any DPV. However, the motor, propeller and nozzle must be engineered as a system to realize maximum efficiency.
The majority of DPVs have motors designed to accommodate a readily available propeller and nozzle that was never fully optimized. Some companies are now even trying to add a new propeller to a piecemealed design in an attempt to improve efficiency.
The test data shows the smaller diameter prop and nozzle on the Genesis is proven to produce significantly more thrust at the same input power level than the DPV's using the larger "Oceanic" style prop and shroud, even though propeller efficiency increases with diameter. This is due to the highly integrated design and full nozzle geometry that ensures the flow over the outside of the nozzle is controlled, instead of turbulent like the "Oceanic" style shroud which is essentially just a funnel for the propeller. An added benefit of a properly designed nozzle system is that the thrust column stays more consolidated so it can be operated closer to a silty bottom without stirring it up and ruining visibility, which is essential in caves.
Looking at the cross section of the Genesis nozzle, it becomes evident that it is actually a round wing and it provides thrust solely due to the pressure differential across it from the higher velocity flow through the center. The nozzle material is a positively buoyant rigid foam that provides 2.3lbs (1kg) of lift, enabling the body to be nearly 2 inches shorter.
The motor is a frameless brushless DC unit, shrink-fit into the aluminum tail cone. This means the heat from the motor is being conducted directly to the water for maximum cooling. The motor controller is also heat sunk directly to the water through the tail cone. Even after running for over an hour at maximum thrust, the motor and controller do not get hot like other scooters that try to transfer their heat through the stagnant air inside the housing, over heating their batteries in the process.
The control handle is spaced off the nozzle to help react the torque at high power and also keep the hand from disturbing the flow around the outside of the nozzle. The ON-OFF trigger can be locked OFF to prevent accidental actuation by rotating the stainless tab under the lever or locked ON for extended cruising by depressing the trigger and rotating the tab over the trigger. The thumb lever controls the variable speed and provides a redundant OFF position when the lever is rotated all the way down. Only one hand is needed to operate all the controls. Mounting holes on the stainless bridge are provided for bottom timer and compass mounting. The tubing that encases the control wiring between the handle and the body has been proven on ROVs operating more than 1400ft (425m) deep.
The underwater connector on the front of the body serves two purposes. First it enables the scooter to be recharged without having to open the body, reducing the chances of contaminating or damaging the main body seals and secondly the cover incorporates an "enable" circuit for the motor controller so that the motor will not run if the cover is not installed. This is the third safety feature to prevent accidental operation of the DPV. By removing the cover, the controller is de-energized and draws no power, so the DPV can be stored closed without the quiescent power consumption of the controller draining the battery. A circuit inside the DPV prevents power from being present at the pins when the charger is not connected and ON. The Lithium ion polymer battery packs do not off gas hydrogen like SLA and Ni-mh batteries can, so there is no reason to open the body when charging the batteries. A vent plug is next to the connector to vent pressure from changes in altitude or weather and can be used for vacuum or pressure testing of the DPV. The Plastic ring around the nose of the DPV prevents damage to the anodizing when the scooter is stood on end in a tank rack.
Modular battery packs are used so that the Genesis 600 batteries can be separated into two 299Wh batteries that fall below the 300Wh DOT limit for Lithium batteries on passenger aircraft. The small (2.6 x 4.9 x 7.0 in.) rectangular packs easily fit in carry on baggage. The clamping system is the same for both battery packs so changing from the 600 to the 1200 requires only the different packs and longer body tube. The charger can recharge the 600 batteries in less than 4 hours and the 1200 packs in less than 8 hours
