Depthfinder issue

[Reel Ax]

If I go over 7mph my garmin stops reading depth and just flashes. Any ideas on what I can do to get it to read while I'm running?

I had that same problem on my first boat. Try moving the transducer up or down until it works better made some difference but when I had the dealer reinstall it the problem totally went away.

Transducer probably needs to be lowered just a bit.

I have the same problem. Will look at it today and see if it can be lowered.

It swivels on the bracket. Just a hair down works for ours.

Typical issue ... As others said, try to slightly rotate down, or actually drop it in small increments as possible.

I also have the same problem with the Garmin GPSmap 421, I will lower mine this weekend and post the results.

I changed the angle slightly and it helped. Now i can go 10mph! Will try lowering it in increments to see if that helps. It's the "dirty" water that causes this. The air cavitation bubbles hitting the transducer as it flows past the toon. If you can get the transducer below the cavitation bubbles into pure water you should be golden. Now I need to follow my own advice....when I next see my boat!
