Interphase DG-1

[bspeth]

Anyone have one of these instrument mounted depth finders? mine registers depth fine while stopped or at low speeds,but goes to three dashes while cruising. The manual says to adjust the angle of the transducer,but I do not know how to do it.Any help would be appreciated-Blair

Re: Interphase DG-1

I have a Lowrance but lose everything but bottom. It reads depths at 40 MPH but everything else disappears at about 6 MPH. Lowrance said the same-- adjust the 'ducer. They suggested pointing it more toward bottom. When that did not work support suggested a new unit. Not a new 'ducer as I did that~~~ next will be Garmin.
