The Drives: Efficiency meets Maximum Thrust

  1. High-performance patented gearless direct drive
  2. Hydrodynamically optimized thrust nozzle
  3. Ergonomically designed holster with extended thrust support and adjustable positioning
  4. Full-length rubber strap for flexible yet secure, slip-free fastening to the thigh also on neoprene
  5. Leg buckle
  6. Rubber ring for leg strap overlenght
  7. Battery connection plug
  8. Double-joint connection for full range of motion combined with high torsional rigidity

Tool-Free Propeller Removal

The propeller can be quickly removed without tools, even while wearing neoprene gloves, making maintenance effortless—even during a dive. In the event of an obstruction, such as seaweed, the diver can easily clear and reinstall the propeller. The self-aligning mount enables precise, blind reinstallation for fast, hassle-free operation.

The Control Unit: Intuitive Control for Maximum Flexibility

  1. Rotary knob for stepless thrust control
  2. On/off switch
  3. Sliding cover for mechanical LED cover
  4. Push button for activate the status light (LED automatically turns off after 5s)
  5. Status light (LED)
  6. Connection to the battery unit or remote control unit. The two connections can be interchanged as desired.
  1. Rotatable and height-adjustable in 90° increments using the indexing mechanism and 3 screws.
  2. Support system with Security Lock and angle adjustment (Tac-Clip)
  • All control elements can be easily operated with neoprene gloves.
  • Position of all control elements can also be felt with the finger.
  • Direct continuation with set speed after switching off and on again.

Remote Control Unit: Engineered for Freedom and Stepless Control

The optionally attachable remote control unit fits securely in the hand and is designed for effortless operation - even when working with tools. Its flexible coiled cable provides maximum freedom of movement and allows the control unit to be positioned exactly where needed.

When connected, the remote control automatically takes over seamless thrust regulation. When it is not connected, control remains with the control unit. The hand-held control unit also features a magnetic mount.

The symmetrical design and adjustable, rotatable rubber strap – serving as a safety tether- make the remote control equally suitable for right- and left-handed users.

The connectors for the battery and remote controller are interchangeable, providing maximum flexibility. Combined with the coiled connection cables, the control unit can be positioned and carried wherever it is needed. This enables intuitive control while ensuring reliable operation – even in demanding operational environments.

  1. 360°-rotatable safety tether
  2. Ribbed, self-locking control knob for easy operation, even while wearing neoprene gloves

The battery unit

The Smart Power Control Unit combines intelligent power management with an integrated battery for reliable, hassle-free operation. A simple slide switch activates or completely shuts down the system. In OFF mode, the unit enters an ultra-low self-discharge state, allowing it to be stored for months without recharging –without the risk of deep discharge.

For added convenience, the system automatically powers down after 1.5 hours of inactivity, conserving energy and extending battery life.

  8. Burst protection

The smart Power Control Unit can be modularly attached to a wide range of diving equipment including buoyancy compensators, live preservers, plate carriers, and carrying belt. A specially designed carrying belt is included and housed in a durable, Molle-compatible bag for maximum versatility and ruggedness.

A three-prong plastic Molle quick-release system is also included, providing a fast and secure alternative to conventional webbing. The Power Control Unit bag is designed to release trapped air immediately during descent. 

  1. Double-sided two-row MolleE system for attaching the unit to equipment such as a buoyancy compensator
  2. Three-row MOLLE system for attaching the Power Control Unit to equipment such as a carrying belt or plate carrier
  3. Three-prong quick-release system as a fast-release alternative
