ETF50D 50 kHz Transducer

SKIPPER 10×16° (Art no: ETF50D) 50khz/ 2kW External mount housing

The thirteen- piezoceramic element, sets the standard for performance and price its class. The expoxy resin housing with integral acousting 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.


  • High echo amplitudes achieved with excellent transmitting and receiving voltage response
  • Excellent ring suppression and very low Q provides for remarkable echo definition
  • PZT piezoceramic array provides high acoustic efficiency
  • Good definition in hard bottoms with low sidelobes
  • Streamlined shape reduces drag
  • Blister housing minimizes installation cost


  • Housing material: cast urethane
  • Standard cable type: C37-shielded twisted pair (2-18 AWG) with braided shield, black neoprene jacket, 9 mm (3/8\”) diameter
