My first screen capture on 1197 now what is it?

Hello, I finally found a spot that worked on my wx1880 and with some electrical tape got it work pretty good. I was crusing a metro lake breaking in the kicker, when i ran across this. Could someone explain what the white spots are and are those fish on the right side??? I am guessing this is gravel mixed in with mucky bottom but that is my guess. I am now able to get readings around 40 mph with my 1197 HDSI transducer as well. Hopefully I have found that magical location.

Isolated patches of hard bottom surrounded by softer bottom. Here are some similar examples.

I need to get me one of those sonars!!! hah… maybe it’s buried treasure and will help pay for your new unit??

I have used mine in the recovery of a person who drowned, will never have a different one on my boat!
