Details
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.
LCD DisplayThe easy-to-read backlit LCD display shows real-time status of output voltage and current, fuel gauge-type display of the battery life, output time in seconds, unit temperature and waveform settings.
The rotary Output Frequency switch controls the frequency (pulses per second) of the LR-20 in 5 and 10 hertz increments. The Duty Cycle switch controls the percentage of time the output pulse is on. It also allows switching to straight DC or gated bursts of either 2 or 3 pulses. The timer reset button resets the number of seconds the output of the LR-20 has been active.
SafetyOperator 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.
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.
CompatibilityThe LR-20B uses the same electrode, cathode, and battery connectors as the LR-24. This will increase your flexibility in large field operations and increases the versatility of your inventory of electrofishers.
