Ok, so today I hooked up my coaxial cable antenna to the Deus, put the control unit in a waterproof case and off I went to the lake to try it out. It worked flawlessly, exactly the same as dirt fishing. The only problem occurred when the control unit was a few inches under water and the signal was lost to the headphones. Didn't have any extra cable with me to try attaching it to the control unit and extending it to the end of the upper shaft to see if that would produce a signal to the headphones. Has anyone else had this problem and if so, how was it resolved, if it was resolved? Thanks
