If you're located near the Bay Area, CA Chad B has agreed to come out and bring his vaunted calibrating skills! However to make this trip worth his while he will need at least 8 calibrations to make it worth his while. I'm in so that means 7 more people. He will keep it his normal fee $425. However, if we can't come up with 8 people he will ask for $600 in travel expenses. His only open block of time is currently in May. If anyone is interested post here or message me. We need 6 more people to make it happen.
