ETF50D 50 kHz Fishery Transducer

The ETF50D is a 50 kHz Fishery transducer. The thirteen- piezoceramic element, sets the standard for performance and price in its class. The epoxy resin housing with integral acoustic window achieves a balance of very low ringing, low sidelobes and excellent sensitivity at a reasonable price. When used with our urethane fairing, the installation is simplified, and the fairing will not swell or rot.
