System Contents



For safety, the backpack uses state-of-the-art accelerometer technology to constantly measure the tile angle of the backpack in all directions. When ducking under branches, vegetation or obstacles at the side of rivers, the backpack will momentarily disable fishing until the operator straightens up, allowing maximum mobility with minimum hassle – but should the operator have stumbled and fallen, the backpack will then enter into its “emergency” state, and prevent further operation until fully reset. Additionally, the backpack includes an optical immersion sensor ( minimising reliability issues commonly seen with conventional float-type sensors) that stops fishing should the operator wade or fall into deep water, and an internal thermal sensor to ensure the unit does not over-heat under high-load conditions.


Battery Modules

‘Quick-Change’ battery packs to allow the user to swap power sources without the need to open any housings or re-route cabling. Several sizes (and weights) are available to suit every operator and budget.



To minimise stress on wildlife during the fishing process, the backpack has been designed to meet the latest best practice electrofishing guidelines, and utilises high-speed microprocessor technology to digitally synthesise the output waveforms while closely monitoring delivered power and voltage.

Should the anode and cathode be shorted together, the system will power limit, alerting the user with a visual message and audible tone, and resume fishing when the short is removed without any damage to the unit.
