Just finished reading all of these posts, thoughts and info given etc, given by Carl and everyone else.
Outstanding test of these probes,

I am interested in the hollow flow thru probe, for the upcoming mads to my QB 79, 22 caliber rifle.
Has anyone followed up with any more test results?
RIP Carl, you have earned it....as your actions have proven, beyond any shadow of doubt.

Tia,
Don
