I was using my Marcum on Sunday in 55 feet of water, the zoom was off.
In order to seem my lure, I had to turn the gain up. However, when I turned the gain up enough to see my lure, there was all kinds of what appeared to be interference flickering in and out in the bottom 20 feet of the screen. If I would turn the gain way up , the bottom 20 feet on the screen would be completely lit up. This interference only appeared in the bottom 20 feet, I thought it might have been some insect hatch or plankton or something like that.
I was the only person within a 1/2 mile of this spot, there were no other electronics anywhere near my Marcum, however I pushed the IR button a few times and the interference completely disapeared, and I was able to see my lure clearly.
So why did the IR clear up whatever was on the screen???? Especially when it didn't seem likely that it was caused by any other electronics?
When I have fished in shallower water (35 feet or less) I have never experienced this.
Not complaining, I love the unit, I just don't understand how the IR cleared up what was on the screen...
Wasn't terrible at a state park beach. Antelope island maybe. I wouldn't recommend it as a beach destination tho. Figured I was there, I'm getting in it.
The water looked and smelled disgusting with hundreds of thousands of birds sh*tting in there. About as gross as the Salton Sea. When I duck hunted there I didn't even want to touch the water.
It's kinda gross with the algae in the summer but I got in it anyway. Wanted to see the increased bouyancy at work. You can kinda tuck yourself into a ball and you'll just float with your head above water. When dry off you look diamond encrusted with the salt.
We went to the flats too. I dipped a tire on the rental car onto it just to say I’ve been there,but it was still pretty soft from winter melt. After seeing some moron in a BMW suv get dragged out of the muck I had no intention of repeating his stupidity.

Any ideas?
