there are a ton of black freshwater mussels in the lake i fish .... when the water is down you can sometimes see their beds.
installing my new graph tomorrow a lowrance elite 7 with downscan...

i am looking to find some shell beds in deeper water... anyone have any expert opinion on how to determine what a shell bed is on a graph like this ???

or even further am i wasting my time doing this? i fish martin creek lake since its so close to my house and there is NO grass.... and not a ton of stuckture ... just having ideas in my fat melon lol

i wish i was that good at my electronics. do a google research on mussel beds it will tell you what type of bottom they like and average depths. then the search begins from there if you find the right one it can be lights out.

You can definitely find them with your downscan, they look like a slightly thicker, uneven black line right on the bottom of the graph. Hopefully someone has a pic. . .

I think those might've came from Doug V... The main think you'll have to look for with side imaging or 2D Sonar is the hard return which the green and red color platelet does very well.

wow very nice guys! .... awesome info! yeah i did a google and youtube search and i found sev vids showing kvd and others wearing them out on shell beds... i know they are in this lake .. looks like i will be spending some time behind the graph without a rod in hand soon!

That pic is from a Humminbird graph, the only way you might have the red/green option is while on "night mode" but I don't know if the elite 7 does the night vision option. I only have HDS graphs and they have it, not sure about the elite.
