I own two KD200's, one's a color mine, the other is the large b/w. I've also had the privilidge to demo a compact on several occasions. I've figured a way to manupulate all three in such a way as to allow the user the option of entering a branch line, in any direction, or, staying in the original line. There are no strings attatched(no pun intended). There is absolutely NO damage to the unit. It is impossible to turn back on itself. Multiple branchlines can be inspected in a single pass, without putting bind on either the unit, or the push rod. I'd like to discuss it with someone who can tell me if it needs to be patented, before Ridgid would be interested? Please e-mail the name and number of such a contact.
