I've been using mine for two weeks now, cant say I am catching more perch that sight fishing, but its pretty educational, also had a couple of pike nose into the picture and scare the bejeepers out of me, wouldn't usually see them looking through a four inch hole. Was in deeper water today and didn't even try it as the x67 was dialed into the perch just fine. Looking forward to getting out in the trout grounds and trying it, not enough ice for me out there yet. Just when I though I had everything, they came along with this.
The panner unit works very well too, have seen my partner struggle turning wires over the years by hand.
