I have recently bought a Garmin 160 Blue fish finder.
The unit loses lock on the botton and will not show depth once you start moving much greater than about 5 kts. Once you stop it takes upto 60 seconds to give you a updated bottom sounding.
The main unit has been back to Garmin and I am on my THIRD replacement, and on my second transducer.
The transducer is mounted about 2-3" outside the prop arc and about 0.25" below the transon, measured to the bottom of the transducer. and mounted level with the water (at a angle to the hull, being a V.) I have tried diferent transducer depths with no success.
Boat is a Ribcraft 4.8
Has anyone else had there or similar problems?.
Is it just my setup or does Garmin have a problem>?.
Any comment welcome as I am stuck.
