I have been doing pretty well with the narrow coil on the MK. I agree the Tesoros with a small coil can get you much closer to the iron structures in tot lots but much of my hunting has been in the alum trash areas picking through can slaw where most pass out from migranes
Never seen the raptor tool you guys are talking about.
Just shipped a small batch of my park probes down to Richard at backwoods detectors. So far it's been workin well for me and not getting booted out of anywheres.
