Seems like you, suspected , WRONG..... Look up Standard/Horizon
Communications, in your favorite Search Engine. They are still
a Big Player in the non-commercial Marine Electronics Business,
and doing quite well.....

Bought by Vertex, and still in operation

http://www.standardhorizon.com/

They are out of the instrument biz, but still have "some" old parts
laying around. The tech department is very helpful if you CALL them
and ask nicely.

Yes,you're right, their tech dept is very helpful but they have
nothing left that fits my need.

If I can't get the old DS-1 working I may try a cheap inside the hull
depth sounder, eg Uniden QT 206 which you can get for under $100 and
doesn't need a hole in the hull. Some say they work fine.

Thanks for the help

Generally recent depth sounders work on one of two different
frequencies. you might try to determine what frequency your instrument
works at and try a new transponder of the same frequency.

You can but standard transponder heads designed to epoxy inside a
fiberglass hull. I have been using one for ten years with no problems.
I believe with a 'Standard" display.
