A friend gave me an new/never used AirMar Bronze Thru-Hull Trieducer Multisensor today. Anyone familiar with it? I think it came w/ an Impulse Depth Finder. The tags show AirMar 653-01-00<br />IMM2004A/573 for the depth sounder (200mhz). The speed paddle which is inserted through the center (also has the plug)of the transducer. Tag says: AirMar 2-AO IM 2004A/25-121.<br />I have an old Impulse 3100 LOran/Depth finder that I am currently using, so don't know if it woulk work on it or not. Any Information would be great. Thanks
