I'm losing my mind, but if I keep the part that tell me when I have to pee I should be OK!
I have owned three dual frequency units, at least one of them that could display both frequency's on different windows at the same time. I didn't find it very helpful so I ran it with both frequencies overlaid on the same window. About the only advantage I found was you could see fish (or downrigger ball) farther out from under the boat (larger cone angle) on one screen and not have that muddle up what was right under the boat. Seems to me there are higher resolution, more colors, more powerful units available for less money.
I have a dual frequency unit that will overlap frequencies or show in separate windows. I've stated in another post that I use the wide angle freq when tracking the downrigger. I will also use the wide angle also for scanning shallower water when I want to scan a section of the bottom larger than a tennis ball, bowling ball or beach ball. Unfortunately the wide angle freq doesn't show fish as well as the narrow freq.
