Innovative Technology Airmar’s commitment to innovative technology has produced the SS538. This broadband 200 kHz transducer has a Q of 2 and very good sensitivity. It enables users to perform accurate surveys in shallow-water with high resolution. This transducer can also be “chirped” with a long pulse over a wide-frequency band. Users with adjustable-frequency echosounders will be able to regulate the operating frequency and tailor the beamwidth to specific survey conditions. Options • Impedance to customer’s specifications using matching transformer 2 kW Broadband Applications • River, harbor, and estuary survey Features • Broadband with low Q of 2 • Minimal sidelobes for concentrated energy on target providing excellent definition • Portable for survey applications • Short, threaded stem simplifies attaching to portable-mounting apparatus • Internal transformer provides impedance match to echosounder and allows use of longer cable • 2 kW RMS, power rating is at 2% duty cycle • Robust, stainless-steel
