Cane Pole,
Not a Dr. Depth user myself – my wife put her foot down on this one… but WarrenMN (aka: Warren Parsons, walleyemapper ) off the Yahoo Si site has been using it and doesn’t seem to mind sharing information about its use. He does all of Doc Samson’s mapping and sells some to the Wally guys on the side. I would contact him and see what you both can come up with. I tried his web site but it keeps giving me a “Page Cannot Be Displayed”.
