Dell, just an update on your post on this thread. I just got my Detech coil from Kellyco. It is for my Omega, and yes it fits on my GB Pro works just fine in my test garden. The only problem I had was the ground balance. I could not get either machine to ground balance with the coil. I switched back to my stock coils and they would not ground balance either. This was the first time this has happened here at my house. After a little investigation, I realized the problem was my wife's recently updated WIFI connection. Moving farther away from the source, both units and coils GB correctly. Just something else to contend with in real hunt situations.
I just started testing the new coil. My deepest targets have been only 7 inches. I was impressed with the "effective depth" on the deepest targets. Vdi and tones were solid, and the coil seperates good between an iron nail and a dime just like the stock DD coils. More updates to follow after real hunt situations. Hope this helps Txquest
