It was working fine weekend-before-last, when we raced. Going out today: Bupkis. Just "-"s on the display.
Luckily: I have the sounder for our Garmin GPSMap 498C, which I believe is the same sounder the Raymarine ST60+ depth gauge uses, as yet uninstalled. So, between the 498C and the spare sounder, I should be able to easily determine whether it's the sounder or the instrument.
We would really
prefer to spend what funds we have available on upgrades
, rather than repairs. *sigh*...
