Apex Backpack Electrofisher

The New Apex of Backpack Electrofishing

Apex Backpack Electrofishers are transforming fisheries research. You asked us for data and standardization and we listened. Apex electrofishers record electrofishing inputs and outputs every second while displaying them on a beautiful color LCD screen. In the field or the office, download your electrofishing data in seconds via USB then analyze over 20 variables.

Apex is Trending

While electrofishing, the full color LCD screen displays 3-minutes of electrofishing output graphs for Peak Voltage, Peak Current, Peak Power, and Percent Load. A quick glance at the screen provides rapid analysis of trends in the backpack's performance to give you confidence in your settings and technique.


Integrated GPS

Integrated Global Positioning System (GPS) eliminates the need for manually recording location data. GPS coordinates can be exported and used with standard mapping software to create professional displays.

The Most Features of Any Backpack

With more than 50 years of building electrofishers under our belt, we pulled out all the stops when designing the Apex. Dual Channel Outputs, Widest Electrical Output Ranges, Timer Alarm, Help Tutorials, Diagnostic Mode, Animated Waveform, Trend Graphs, GPS Coordinates, Battery Meter, Data Recording, Data Download, User Performed Software Upload, and more.

Standardization is Standard

The APEX revolutionizes electrofishing output standardization. Onboard help and graphed trends provide realtime information to standardize electrofishing outputs between waterbodies with differing environmental conditions.

Get Help In The Field

Did you forget what frequency to use? The Apex comes loaded with an onscreen help system containing tutorials, suggestions, and tips that make your fieldwork more effective and informed. If you encounter any issues that you are unable to resolve, quickly download and send the recorded diagnostic data to Smith-Root for help — even while in the field.

Apex Marks the Spot

The integrated Global Positioning System (GPS) revolutionizes the recording and plotting of electrofishing transects. Utilize the GPS coordinates on your computer or in Smith-Root's electrofishing app to create instant electrofishing maps.
