Portable Electric Fishing Devices by Hans Grassl

The portable electric fishing devices by Hans Grassl are renowned for their reliability and performance, particularly in the context of scientific research and fisheries resource management. These devices are designed to temporarily capture fish without harming them, thus facilitating their identification, measurement, and release.

General Technical Specifications

The battery-powered portable models from Hans Grassl feature the following specifications:

• Power supply: 12 V rechargeable battery

• Output voltage: 600 to 1000 V DC

• Current type: Continuous or pulsed, with adjustable voltage

• Power generator: Converts battery energy into pulsed electric current delivered into the water

• Anode (positive electrode): Usually a metal ring mounted at the end of a pole, operated by the user to direct the electric field

• Cathode (negative electrode): Submerged in the water, often dragged behind the operator or attached to their belt, completing the electrical circuit

• Power source: Rechargeable battery (typically lead or lithium), providing sufficient energy to generate the electric field in the water

Safety and Regulations

The use of these devices is regulated in many countries, requiring specific permits and proper training. The current can be dangerous to humans and animals if misused. Therefore, it is essential that these devices are handled by trained professionals using appropriate protective equipment.

Available Accessories
