My new (old) boat has an Autonnic depth sounder
and everything appears to be working fine on it, but the two buttons for setting and using the depth alarm
and other functions are a bit mysterious. I thought I had gotten them figured out, but its behavior still doesn't match my previous guesses.
Here's a photo
of the model I have (the one in the middle):
If anyone has the original owner's guide and could send me a copy, or knows how it works and can describe from memory, that would be much appreciated.
I contacted Autonnic, but they were unfortunately unable to help (though they were great about sending along a replacement wind vane
free of charge for my wind
instrument -- outstanding customer service).
