I purchased the Sanderson Accu-fork II several years ago. I was never satisfied with it. The closest that I could get the calibration was -0.43 cents. I also found that it took over a minute for the pitch to stabilize. The fork wasn't cheap. It was $150 US plus shipping. I set it aside and never have used it. When I purchased my Pocket RCT, it came with the Reyburn Cyberfork. Dean Had calibrated it to +0.09 cents. It is very accurate. I used the Cyberfork for my tuning test. The pitch of my A4 ended up at only +0.2 cents giving me 100% on pitch. I had not heard that the Cyberfork had a loud second partial until after I had taken the test. I don't think I have ever heard it. Dean does not recommend using the fork for the tuning test. IHe used to sell the Cyberfork for $30 US. I don't know his current price.
