Thanks for the positive feedback guys.
Bing, I am able to get the double echos that you were asking about in your post. I was mostly fishing the squid grounds that day, with a 100 other boats
. Lots of interference until I got away from the fleet. It seems that if I'm too close to other boats, with more powerful sounders, I get some interference. I was getting the interference with the in-hull as well. It looks like really thin dashed lines. Anybody else experience this?
