You may also want to consider the F2 for around the same price as the ace. I have seen the Deltas advertised for $242. I have owned the ace and used the F2 but not the delta. If the Delta performs similar to the F2 I would pick it. The pinpointing on the ace can be tricky and has frustrated some people. You get a 5 year warranty with the Tek. 2 with the garrett. I think the build quality is a little better on the ace. The Delta has numerical ID, the ace dont. This can make a difference. For example on the Omega I have most nickels hit at 56-57 id number. I have never found a nickel that registered 58-59 but those numbers are in the nickel range. I do not even dig those signals if I am in a real trashy area because most of them will be pulltabs, trash. So the numbers can be of some help in deciding to dig. If you just plan to beep and dig then it will not make much of a difference.
