Simplified manual control knobs, and streamlined settings allow adjustment over output frequency and duty cycle. All controls are housed inside of a non-conductive, waterproof enclosure with a shatter resistant cover. The externally accessible anode and cathode plugs and battery connector make the connection of electrodes and battery packs quick and easy.
- 400W continuous output power
- Easy to use rotary style controls
- Rugged and safe design
- Weighs just 16.55 pounds
- Standard 1 year warranty
- Made in the USA
Operator safety is a primary concern in the design of Smith-Root electrofishers. Tilt sensor, water immersion sensor, and cover open sensor will automatically shutdown the electrofisher. A power output audio alarm and flashing light let all members of the collection crew know the electrofisher is active.
Packframe and Suspension
Adjustable suspension harness and packframe can be customized to fit most people. Quick release latches allow the LR-20B to be removed quickly if the operator falls or becomes injured.
The LR-20B uses the same electrode, cathode, and battery connectors as the LR-24 and Apex backpack electrofishers. This will increase your flexibility in large field operations and increases the versatility of your inventory of electrofishers.
