When I was told about shaded depths at a seminar, I kind of yawned (not literally) about it, but after using it on a couple pieces of new water lately, I can honestly say, that it is one of my favorite things about my 997, other than the side imaging.
If you dont know the body of water well, shaded depths will simplify your ability to navigate, particularly while establishing trolling patterns.
Here is a series of pictures from Gull Lake in Mn. I have never fished Gull lake, but used it as a model for highlighting what shaded depths can do for you.
Shaded depth turned off.
Shaded depth set to 25 feet:
15 feet:
10 feet:
5 feet:
On another piece of water, I had fopund the smallmouths on mid lakes humps that topped out at 7 feet. after exhausting all of my known spots, I changed my settings to 7 feet, and wow, about 9 other spots screamed at me to come fish them. It eliminated a ton of investigation time on the water, and will put more fish in the boat. guaranteed.
Next time you are out, give it a try it, I will bet you will like it or Ill give you your money back!
