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.
