Thread: My transom mounted transducer

The picture is perfectly clear. You can easy see.



Sorry not good on attachments

The fish it marks are not shown as arcs. I can see baitballs and bumps on the bottom, but the suspended fish should be shown as arcs.

I am suspicious the transducer is the issue here.

Arcs are created by the target being in the Sonar cone long enough to be at different distances from the transducer as the target passes thru the Sonar cone ...



Can you post a picture or your transducer installation ...??

A photo would certainly help

Not sure you can see it, but it is mounted at an angle.

Whenever I get up to about 15mph I cease getting depth readings and the numbers on the screen go crazy wild. The only number that makes sense is speed at that point. I also see water splashing upwards off the unit when moving.

The should be pointed straight down. I would say at 15mph is when it air is starting to be drawn down around the transducer causing it to lose the reading.
