High-Strength for Harsh Environments The high-strength, cast-steel CS229 stands up to harsh environments. It has been designed to facilitate service or repair. The transformer can be accessed from the top of the housing for a quick, field repair or impedance change. The transducer is removable from the outer, thru-hull housing and can be replaced while a vessel is underway. 1.5 - 2.1 kW Applications • Large, steel-hull vessels • Harsh environments including ice filled water Options • Impedance to customer’s specifications using matching transformer • Available as special-order unit with 12 kHz, 24 kHz, 28 kHz, 30 kHz, 33 kHz, 38 kHz, or 50 kHz array • Steel hulls only • Versatile housing accommodates variety of frequencies for most navigation and survey requirements • Low-ringing arrays provide good bottom detail in deep-water • Available with stainless steel or “acoustically transparent”, urethane window, depending on the frequency • Features inner, CS234 transducer and outer, CS229, thru-hull
