HDS & SS install on Ranger 681

[bklimek]

I recently purchased a HDS Gen 2 with structure scan and I have a question on installation. I have a 1999 Ranger 681. I'd like to install the structure scan transducer under the step mount or jack plate. Problem is my current 2D transducer is mounted on the bottom of the transom. I want to limit the number of holes that have been drilled. I've read that the SS ducer should be below the 2D transducer and it also should be within a foot of the transducer. I don't want to be drilling multiple holes so I'm seeking some advice on where to put the SS transducer.

bk. I had that problem with my 680C. Two different sets of holes, and had to mount the trans. for my new HB 798 SI. I bought a pc of 5/8 in. plastic that covered all the hole( i filled them in with silicon first)Can move things around and no more holes to the hull.

Yes they sell them as transducer mounting boards at many different places.

If you have a jackplate, that is the best route. No holes in the hull.

I do have a jackplate but then where do you have your 2d ducer mounted?
