Chris Borgen and Eric Foreman dove on an unknown target that had proven difficult to image. This target lies between two rises in the Lake bottom which prevented detailed imagery from a tow fish. These images were taken with a hull mounted unit.
In this first image you can see the two divers approaching the target. No bubbles are present as both divers are on rebreathers. Target depth is 180' fresh water.
This next image is of the same target using a hull mounted side scan.
