I have an old Heathkit graph recorder with a single transducer. Someday I would like to make something of it if I ever collect some more transducers, just something to play with. It takes about 4" spark paper but I cant seem to find a place to get it, any ideas? also interested in any good reading on rigging up a cheap sidescan, or any good reading for that matter.
Thanks
