When it comes to transducers remember this: 1) 'Shallow' water HST-WSBL 106-72 transducer will operate on 2 frequencies on the HDS models: 200 (20°) & 83KHz (60°). 2) Deep' water HST-DFSBL 106-77 transducer will operate on 2 frequencies on the HDS models: 200KHz (12°) & 50KHz (35°). These are comparable to the Airmar P66 (ESA931) 200 (11°) & 50KHz (45°).
