Does anybody know of anyone using a GARMIN Chirp GSD 26 sounder box. I'm getting no sounder signal and trying to determine if it's my transducer or the GSD 26. GARMIN has no ability to test my GSD 26 and my Ducer is a fairing block. The boat is slipped at Wrights landing and I was hoping to find someone nearby that I could swap the unit with to determine if its the sounder box or ducer.
Thanks Tony
