SKIPPER 11x19° (SKIPPER Item no. ETF38E) External mount housing

Excellent performance at 38 kHz is provided by a thirteen-element piezoceramic assembly mounted in a durable, SEALCAST, urethane housing. This design provides high source level capability, low sidelobes, low ringing, and maximum reliability. Used with our urethane fairing, the installation will be quicker, and the fairing will not swell or rot.

Features
* Very high source. level capability for good deep water performance
* Low sidelobe minimize spurious echoes
* Low ringing for good discrimination of fish targets
* Seamless SEALCAST urethane housing for long life underwater
* Streamlined shape reduces drag
* Blister housing minimizes installation cost.
