PERFORMANCE
Through the application of hydrodynamic design, developed via intensive research with the University of Manchester, Northern Diver have maximised the efficiency and power of the DT4 Thrusters to reach their fullest potential. We are constantly re-working to ensure the kit will provide the best streamlined profile underwater, reducing drag and increasing the speed of our DT4 Dive Thrusters. The development of a sleek battery cover and ensuring the battery housing harness remains as low profile as possible further enhances performance. Additionally, there is a dual battery option, with compatible harness to further extend time and productivity.

ERGONOMICS
The various user groups applications have been considered when designing and configuring the thrusters harness systems. The equipment has been refined for seamless integration with the user’s standard kit. The thrusters include two choices of harness and belt for wearing the kit, that is interchangeable.
• Tactical harness improves comfort, practicality, and usability, the controller can be configured to right or left.
• A tactical lightweight belt with removable shoulder straps to further improve integration with fully kitted operators.

The tactical harness is available in S/M and L/XL sizes and the tactical belt is available in one adjustable size to cater to a wide range of combat swimmers body types. In both configurations the battery pack is protected and securely housed against the swimmer’s lower back. Both systems feature quick release buckles which allow the battery pack to be changed under water. They also have a MOLLE System for storage.
NIMROD - REMOTE CONTROL
In addition to the manual control provided, the DT4 Thrusters have the capability to be remotely operated with Northern Diver’s NIMROD underwater navigation system.
This enables the user to alter their speed without removing his hand from the navigation equipment giving complete control, whilst maintaining a smooth underwater profile. NIMROD console with DVL makes your mission fully covert.
