[quote poorman]If you don't mind, some questions....First and formost, how does the F 4 Pinpoint? Does it have VCO Pinpointing? If not, would you say it pinpoints like the ID Edge?......Does the Tone ID and Number ID give out at about the same depth. I understand these are on seperate circuts? Will the F 4 correctly Tone and number ID a common penny at 8" in an air test? Thanks[/quote] Hi poorman, I am not familiar with the ID Edge, I have been a Tesoro man for along time & I will say say the F4 doesn't come close to the pinpointing of the Cibola I had. It is totally different but once figued out it is not bad at all. I haven't played around with "air" testing because in my opinion this doesn't mean a thing - what counts is how it does in the ground. What I will say is the F4 with the DD coil is a very accuracte instrument, and alot of fun to use. You can read in reviews & on some forums that so and so can accurately id a quarter/dime/or penny/etc. at 18" or 20" with this brand detector or that brand detector. This is bull - I can honestly say that the F4 is the most accurate ID'ing & fun to use detector that I have ever had. Like I said I am a Tesoro man but I do love the F4 & I wouldn't get rid of it for anything. Steve...
