The World's Safest Electrofisher.
The LR-24 Electrofisher is a rugged 24V 400W battery powered electrofisher. It is suitable for extensive field work in any weather conditions. The LR-24 uses premium electronic components and circuity housed inside of a custom molded plastic case.
The LR-24 is the most advanced electrofisher ever produced. The user interface is designed to make the LR-24 quick and easy to use. This has allowed us to offer a number of special features not available on previous backpack electrofishers.
Features
Quick Setup
Quick Setup will select a voltage level necessary to achieve 25 watts average power output through the water between electrodes. This setup uses a default setting of a pulsed DC waveform with a frequency of 30 Hz and a 12% duty cycle (equivalent to a 4ms pulse width). All settings can be adjusted up or down from this starting point to achieve levels necessary for fish capture. This is very useful when electrofishing in a new area and you're not sure what settings to use.
Dual Output
This feature allows the operator to set up two completely independent sets of waveforms and voltages and toggle between them simply by releasing and pressing the anode pole switch in less than one second. This can be very useful if working in waters with multiple age classes, or multiple species where the optimal settings may be quite different.
Safety Features
Emergency stop switch, twin audible alarms, tilt and immersion sensors and Anode-Out-of-Water sensor, combined with the ETL safety certification make the LR-24 the safest backpack electrofisher available. With the ETL Listed Mark on the LR-24 Backpack Electrofisher, researchers can be confident that they are using the safest backpack electrofisher in the world.
Power Limit Key and Power Limit Mode
The Power Limit Key allows the user to limit the maximum average output power. It is defaulted to 400 watts, which is the maximum average power output that the LR-24 is capable of producing. It can be easily changed to a lower limit, which can be useful if a study requires staying within a certain power level. The user can decide whether the frequency or the voltage will be automatically decreased in order not to exceed the output power at that limit.
Precise control over output settings
Voltage can be adjusted in 5 volt increments, frequency in 1 Hertz increments, and duty cycle (pulse width) in 1% increments. This is very desirable given study results which indicate that fish injury rates decrease corresponding to decreases in all of these settings. Exact control of the settings allows for much greater control of the output waveforms.
Numerous waveform choices
The LR-24 can produce straight DC, pulsed DC, and Burst of Pulses (previously known as CPS waveform).
Storage locations for up to 10 user selected settings
There are 10 storage locations available to either pre-program desirable settings or to store settings currently in use. These storage locations are filled with Factory Default Stored Waveforms, but can be replaced one by one with settings the user prefers. These can be pre-programmed before going in the field or saved and stored while in the field. This can be very useful if a setting has been found to be very effective with a particular species, or it can be of use if a project supervisor wants to standardize sampling and provide settings for crews to use in the field. Factory default stored waveforms can be restored if desired.
Rugged ABS Construction
Offers tough structural support in a light-weight pack-frame and integrated control box enclosure. The removable battery cover protects all cable connections from environmental conditions and wear and tear.
Suspension System
The easy-to-fit Cordura suspension harness allows for quick adjustment, making multi-user operations fast, simple and convenient. The quick release function makes it safer to operate in rough field conditions.

ETL Listed
Our Commitment to Safety
You already know our product features. In fact, many of them may play a role in your decision to buy our products. However, there is another important product feature that is not as obvious—the ETL Listed Mark found on our LR-24 Backpack Electrofisher.
The presence of the ETL Listed Mark on our product shows that the LR-24 Backpack Electrofisher has undergone and passed testing to rigorous industry product safety requirements. It's an important step in the product cycle because it demonstrates our commitment to the safety and quality of our products.
Is product safety testing mandatory?
Within North America product safety testing is mandatory before entry into the U.S. and Canadian markets. However, the choice in testing partners to conduct the testing is ours. We chose the ETL Listed Mark, provided by Intertek, for a few reasons:
- The ETL Listed Mark is recognized by all Authorities Having Jurisdiction (AHJs) including building code officials, fire marshals, and inspectors across North America;
- The ETL Listed Mark is accepted by all major North American retailers;
- Intertek is recognized by the Occupational Safety and Health Administration (OSHA) as a Nationally Recognized Testing Laboratory (NRTL);
- Intertek is accredited by the Standards Council of Canada as an accredited Testing Organization and Certification Body.
What's the difference between the ETL Listed and UL Listed Marks?
There is no difference. Both marks indicate that a product meets the minimum requirements of widely accepted product safety standards, determined through independent testing by a Nationally Recognized Testing Laboratory (NRTL).
Are manufacturers required to use UL for their compliance testing?
No. Manufacturers have a choice in their testing providers. The only major requirement is that the laboratory performing the testing is an OSHA recognized NRTL.
How can I learn more about the mark?
The ETL Listed Mark is the legal equivalent to the UL and CSA Listed Marks. A product bearing the ETL Listed Mark is determined to have met the minimum requirements of prescribed product safety standards. More
How can I learn more about the NRTL Program?
The NRTL Program is part of the Occupational Safety and Health Administration's directive to ensure products are safe for use in the U.S. workplace. It recognizes the capabilities of private-sector organizations to determine whether a specific product meets safety standards developed by the American National Standards Institute (ANSI), Underwriters Laboratories (UL), and others. More
How can I learn more about Intertek and the ETL SEMKO division?
Intertek Group plc is an international testing, inspection and certification organization with laboratories around the world. The ETL SEMKO division of Intertek conducts product safety testing and certification, EMC testing and performance testing for manufacturers of household appliances, HVAC equipment, cables and wiring accessories, industrial machinery, medical devices, lighting, telecom, automotive, semiconductor and building products.
