Keep in mind if you are ice fishing, that a system like this will create currents a couple of hundred feet away, so you may have unexpected weak spots in the ice a significant distance from the Kasco unit.
I took some photos that I hoped would show those "thin ice" areas caused when the circulator is moving water under the ice.
A bright day and a lot of glare made them un-usable.
There were two obvious areas where you could see the ice "thinning". After the circulator opened the ice, those areas faded away.
Anyway, always take care when you are on the ice!
