I have been noticing issues with my tzt3 9 depth locking up at 11ft when the water was really 5ft. The sounder does not stop marking fish or bottom, but the depth value freezes on a previous depth. The only way to overcome this issue is to reboot the machine. This did not happen until the new 3.5 update. It has done this 3 times on my trip today. I never had this issue before until this new software update.
