I am looking for a new depth finder... I fish the Columbia river for walleyes (north of Grand Coulee Dam) and often the water is very deep.
It is not uncommon for the depth to drop to 200 feet at 100 to 200 feet from shore. Often it is over 50 feet not too far from shore. Most of the uses I have seen for side image has been in shallower water.
Will the side imaging still find structure at the deeper depths? I am thinking that I would cruse the shoreline and scan out to the deeper water. I would then be only scanning one direction.
Can I find drop offs and submerged structure at those depths to help with walleye or small mouth fishing? Or would I be wasting my money on the more expensive side imaging units? How far to the side could I look?
thanks!
