I've been using mine for quite a while now and I've not had to change a thing about the physical set-up. I've probably used it on 35 or 40 trips and deployed it 100+ times with no problems at all. I'm using a SI unit on front and did have to add the HB interference kit to eliminate the noise on the side image screen. The 2D was flawless. DI was also OK. The large 10 gauge AWG in-line choke on the MK power lines seemed to remove most of the problem so long as I don't run the SI sensitivity in "automatic". I just run it about 10-12 or so and it does well. When I would run the TM wide open (3 MPH) to grab a good side scan of an area, there would be zero noise anyway so it's been a very valuable tool on the bow! No other problem and HB was great about sending the FREE kit to me within 3 days of e-mailing them! Awesome customer service! I just can't say enough about how good HB support is.

Anyway, I'm glad the install tip worked out for you!
