Doug:

Ill ease your pain a little bit. I'll give you $15 for that metric depth mic, provided it has a 3 or 4 inch bridge. I don't need to go to the extent of having a 75mm or100mm base dimension.

Haw.

Seriously, if you want to hustle it, tell me the brand. I assume it's a standard style with the replaceable probes for changing the measured range.

Bill.
