I decided to try out the 5" coil that came with my Racer 2 Pro package after reading how sensitive and deep it is. I also watched the video from the manufacturer showing some pretty incredible air test distances. Now I'm quite happy with the performance on my stock large coil and was pretty excited to see how much better the small coil was going to be depth wise, but honestly, it's kind of a bust. In a clean air test, I can see MAYBE 6" on a quarter, less on penny, dime and nickel. I tried the Deep program and got maybe an extra inch or inch and a half, but no where near the numbers that I saw on the video. I'm wondering if there are some different settings that I may need to make to extract that performance from this small coil. It DID do a bit better on masked targets such as a nickel with a rusty nail on top of it. It detected all the coins (nickel , dime penny, quarter) with a nail either on top of the target or in very close proximity so that was a plus. I'm just a bit disappointed with the lack of real depth. Even in the ground, I would say that 5" is about the limit on this coil. My ground isn't particularly mineralized either so it's not a question of bad soil. Any ideas? Could I have a bad coil? I don't think so, but I'm not familiar enough with the coil to make that call.
