I was using my EM ultra 126sv for the first time this weekend and I had issues with getting the autozoom to function as I believe it should. When I select to go to Clearview, everything looks normal as the unit starts to paint the bottom of the lake and then within 4-5 seconds the screen depths shifts automatically between 8' and 40 something feet and I am looking at a blank screen because I cant see the lake bottom at 100 or so feet. The whole time it is doing this it is in autozoom mode. If i turn auto zoom off and on again it repeats what I just described above - I can see it drawing the bottom for about 4-5 seconds and all appears normal then the screen shifts back to 8'-40' and I can no longer see the bottom.
Any advise is appreciated. Thank you
