i had one of them back in the 70's.it was a very good detector for its time.the freq shift is just a small ammount to allow you to get away from a detector running close to you on the same freq so you dont get interferance from them.some times eletric lines and the like omit a signal you might be able to get away from.all in all it was a good detector and i found a lot old silver with it.

IT simply changes the output frequency of the transmitter. This is intended on the 1220 to eliminate coupled "crosstalk" from other detectors, when they are close. This is kind of a legacy item from detectings heydey, mostly for use during the competition hunts that were popular back when the 1220 was new. I don't believe organized hunts are as common as they once were, and so it isn't such a "hot" feature nowadays.
However, it still works for this purpose and can be useful.

For common use, it makes little practical difference where the frequency control is set, as it doesn't vary the output by much. It can be of some use when you experience electrical noise interference, however.

Any working, name brand detector in decent shape that can be had for $50 is something you should go for.
