I had a request to install two different Rh probes.

Oops, well sorry.

If I have to do 3 holes, which is kind of minimum, and the job is 2000 miles away so I have to take a plane, then I charge for the flight, expenses, hotel and the cost of the probes, along with another flight etc to read the probes 72 hours later, so in some cases I charge $900 per probe.
