Topic: SI fades out at 17-20 feet???

[mccostlin]

Morning all,

first post here. I searched all over the site the last few days and I cant find an answer to my problem.

I have a 797 c2 and the side imaging and down imaging work fine in under 15ft of water. as soon as I head to deeper water the images fade out to nothing at or about 17-20 ft of water. one I head back shallow it starts working fine again.....I have restored defaults and checked every setting on the unit to inlcude making sure the lower range is on auto.

any thoughts?

Thanks,

[Humminbird_Greg]
