Recently I have started having depth sounder issues where I get no depth showing on my Garmin 740S at start up. After about an hour I will start getting accurate readings for awhile (15-30 minutes). Then it will stick on a depth and start flashing that depth for a random period of time. It then may work properly for a few minutes. I had a diver clean the bottom thinking that the transducer may be fouled but that did not help. I could understand if it just wouldn't work but being an intermittent thing is a real puzzler to me. Anyone ever have this problem?
