The frequencies Dave J. has listed are used in real conventional metal detectors, not LRLs. Dave does not design or sell LRLs.
The bottom line is that you can use any frequency you like. It really doesn't matter, as long as you believe it will work. I would suggest experimenting with 65kHz (give or take 10kHz) as this is popular with pistol detector builders.
