Smith-Root Generator Powered Pulsator (GPP) electrofishers are unsurpassed in quality and performance. Our years of experience have helped us to produce the most complete line of generator powered electrofishers offered.

Ranging in power from 2.5 to 9kW, Smith-Root GPP electrofishers can handle all fresh or brackish water conductivities. The generators supplied with each GPP electrofisher are custom-wound to supply the optimum voltages for electrofishing and eliminate bulky and hot power transformers.

Smith-Root GPP's offer the flexibility of shore-side use or in-boat operation. Smith-Root offers everything needed to convert your Streambank GPP into a boat mounted setup.
