A Classic Reborn.

The LR-20 Electrofisher offers the safety and ruggedness of the LR-24 with the simplicity of our classic Model 12, while using the accessories of our standard LR-24. The LR-20 is an ideal transitional unit from our classic Model 12; it shares many conventions as well as the safety and reliability and accessories of the LR-24.

Use it for light-duty electrofishing, or in conjunction with LR-24 units for wider field applications. The LR-20 is a good addition to your collection of Electrofishers in order to cover all field conditions.

Features

Easy to Use Interface

Simplified manual control knobs, streamlined settings allow adjustment over output frequency and duty cycle settings. All controls are housed inside of a non-conductive, waterproof enclosure with a shatter resistant hinged, latched cover. The easily accessible external anode, cathode, control plugs and battery connector make the connection of electrode devices and battery pack quick and simple.

Output Controls

The rotary Output Frequency switch controls the frequency (pulses per second) of the LR-20 in five and ten hertz increments. The Duty Cycle rotary switch controls the percentage of time the output pulse is on out of the time from the start of one output pulse to the start of the next output pulse. It also allows switching to straight DC or gated bursts of either two or three pulses. The timer reset button resets the number of seconds the output of the LR-20 has been active.

LCD Display

The 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.

Safety Features

Many built in features assure that the LR-20 is safe for both operator and collectors. The audio alarm provides a loud audio warning whenever 30 volts or more are present between the anode and cathode. A bright red warning light also flashes once per second while output is active. The emergency shutdown switch turns the unit on when the switch is in the up position but allows the unit to be readily shut down by flipping the red cover down in the event of an emergency. The front cover - which is secured by two over-center toggle latches - must be closed for the output of the LR-20 to be activated. An immersion sensor automatically turns the output off when water should water come in contact with the unit case and a tilt sensor shuts off output if the unit is tilted over too far.

Packframe and Suspension Harness

The packframe and suspension harness allow for various positions of the shoulder straps and waist belt to fit most people comfortably. The straps and belt all have quick release latches that allow the LR-20 to be removed quickly if the operator falls into deep water or becomes injured.

Cross-unit Compatibility

The LR-20 shares the same connectors as the LR-24, making all electrode devices and battery packs and related accessories interchangeable between units. This will increase your flexibility in large field operations and increases the versatility of your inventory of electrofishers.
