Marshall- My Walker blue fork is calibrated to armpit temperature, and is accurate to within plus or minus 0.3cents of 440hz, since I must remove it from my armpit briefly to use it. I have not been able to get this close a result with the nickel plated fork, but perhaps I've been impatient with armpit warming time on the larger fork. You need not worry about this if you're getting the Acufork. I hope you're using the F2 test note method. It should be very accurate with the Acufork, as you can have a long period of time to count comparison beats. Ed > >Hi Ed, >Sorry for the delay in responding.
