Turn Your HDS into a Combination GPS and Fishfinder
The Lowrance BSM-1 Broadband Sounder Module is designed to plug and play with your Lowrance HDS navigation system. The BSM-1 can provide sounder readings from 10’ to over 3000’ depending on your transducer.
The Lowrance BSM helps you best match your fishing location by offering three different frequencies: 200khz for shallow water, 50khz for deep water and 83khz for a mix of both. Whisper technology makes the BSM-1 different from other brands by using a very clean low power signal and an adaptable long pulse and an extremely sensitive linear receiver to provide superior clarity of bottom structure, bait and fish.
