Well they don't allow comparisons on the Teknetics board, so I hope this is OK here. I was a die hard CW relic hunter for many many years up until 10 years ago, at that point I got out of it but came back last December. My main detectors years ago were a Fisher CZ-5 and a Tesoro Sidewinder for the really iron infested trashy areas. When I got back into relic hunting last December, I found alot had changed in the detecting world...namely DIGITAL! I tried a couple of Minelabs but found them way to heavy and just a bit to confusing and expensive...I opted for a Teknetics Omega. I took it first into a Union camp site that I discovered many years ago and had considered "hunted out" the Omega surprised me by producing quite a few nice relics out of areas that I KNOW my CZ-5 coil had gone over in the past. The problem is that many of my signals with the Omega were barely signals and with not alot of depth to be that weak, and TID's everywhere. I came to the conclusion that it seemed the cut-off point for the Omega is about 8". Out of curiosity I bought a used Vaquero based upon what I read about its depth and the fondness I had for my old Sidewinder. Yesterday I was able to put them to the test side by side. My wife and I went back into the old campsite and focused on the most hard hit area. My wife was using the Omega (stock coil, Sens at 95 and disc at 16) and found nothing, I was using the Vaquero with disc just above iron and supertuned. I got a signal in some Rhododendron that was LOUD...problem was there was a great big root that looked like it would be right where I would have to dig. I gave serious thought to skipping it, but decided to ask my wife to scan it and see what numbers she could get......the Omega didn't even sniff on it! Not a beep, NOTHING. I decided to dig it...at about 10" down I got a brass tag. It is definitely CW but don't have an id on it yet. Two feet away another good loud signal..again the Omega gives no indication of a target. At the same 9-10" level....a 69 cal roundball. These are the facts. I still love my Omega for it's light weight, feel and easy use of controls...but it does not get the depth of the V, at least on lower conductive targets. Now, if just Tesoro would come out with a detector with TID that gets Vaquero/tejon depth!
