got a couple questions for you side imaging guru's out there. i tryd out my 997 and957 for the 1st time today. and i have a couple issues. first thing i noticed was my 997 (transom mount) the side imaging looked streaky. the water column was kinda hazy and the bottom lookd fuzzy. i could still see things. but barely. anybody got any ideas? next. my 957 up front works good most of the time. but occasionally flickers different depths. up to 22 feet deep when we wer clearly in 10 foot of water. and then it would just stop for a while. and then start doin it again. and last i hav my interlink mounted up front by the puck and my 957 and hav the gps plugged in to my interlink. along with both units. but my gps wont work. no birds eye view, no marking waypoints. when i push mark. it says no gps available. what do i do?
