[CA] [CA11] installing updates...

[rb56]

thanks very much chuck for your help in detail. i'm going to try this in the morning and hopefully will start giving me a better reading. today on the lake it gave a depth of 2.9 feet yet i couldn't touch bottom with a 7 ft. rod and the anchor rope was showing to be right at 10 ft. deep. also when running back in it was as if the screen had no sonar. it showed the lines but no bottom and no moving right to left as if it froze. hope the update clears this up. thanks.
