Yeah, it seems a minor thing, but the fish alarm/ID issue has been annoying. Sometimes it beeps; other times not. Sometimes orange fish icons; other times nothing. I can easily ID fish by arch signature, but its nice to know if they are close under 200kHz beam or out under 83kHz beam.
More importantly, my wife fishes with me, and she can't see the finder but relies on the beeps. When she's not hearing those, she can get discouraged: "That's a fish finder -- why isn't it finding any fish!?!"
Let me know if you see an improvement in this area as I may not get out on water for a week or so.
