Isn’t the 3030 multi frequency? I know the Etrac,explorers and Safari run 28 frequencies
Yes, all are multi-frequency, but none are really 28 unless you count the harmonics; and if you do that, why stop at 28? Some have said that the ET/CTX machines use as few as 2 fundamental frequencies at any one time. I would assume none of the possible frequencies are that high (compared to the Nox), given that the machines don't do that well on gold.
