Does any one have knowledge of the status/efficiency of the Garmin 100 Blue fish finder? Its been on my boat since I bought the boat 2 yrs ago. Frankly I think its crap or I havent set it up correctly. Read the mamual and experimented if one has to do that but my results arent satisfying. ie rarely shows bait and if Im catching salmon 40 60 80 ft etc it dosent show the schools which are obviously there. Yes, transducer positioned correctly as to the instruction diagram. It wasnt top of the line, price wise, get what you pay for, so with all said, appreciate comments assuming I might have to upgrade.
