Two things to always consider. TX/RX to the correct crystals of equal or near equal frequencies and power. Most all should interchange in some manner. I have a HB skimmer on a low x50. Like Staples says.. "That was easy". Wasn't for explorers, there would be no Ky Lake. Kudos Rickie. Ask Airmar. They useta make transducers for HB and Lowrance. Still make a few I believe.

Hint. Buy transducer extensions and modify the wiring.

The manufacturers generate fuzzy rubber math.....
