Monte, the Racer is a basic enough machine, you don't need to be a rocket scientists to know how to set it up in the field to get the most from it.
I know you have a close relationship with the Racer-Makro-Nokta etc but to me it's just another tool designed to do a job, but for the job i need doing it fell short.
For myself, with stock coil, in my ground it didn't go past 10" in any mode on an English penny. It can have all the 'bells and whistles' of a machine which costs much more, BUT it can't use these features if it can't go deep enough to hit the target in the first place.
You can tell me of tales of how it's in your armoury, how much and how deep you've dug etc etc etc, but I've tried it in my ground and it failed.
Like i already stated, in good ground you could be nothing but pleased with the Racer, probably go as deep or better as any other, but show me one genuine (not sponsored) user video of the Racer2 in 4 bar soil going beyond 10" on an English penny with stock coil and I'll eat my hat!
I don't know what you mean by 'fast', as that could imply the Racer 2 has a very fast response and a fast recovery, which it does, or that it requires a fast sweep speed, which I find it doesn't. I have spent eleven months hunting with the Racer 2 and my other preferred detectors, and worked many challenging sites, and I use a slow, methodical sweep to what I consider to be a moderate, comfortable sweep speed and I get very satisfying depth of detection.
You didn't mention the search mode or settings used, or the coil you used, other than the after-market NEL coil. I have lived in a highly mineralized area in the USA for most of my life, and most of the places I search are quite mineralized. The MMI read-out on the Racer 2 is seldom less than 3 bars, and most of the time it is 4 or even 5. The Ground Balance read-out in most places runs
I'm curious as to your gain settings in such hot ground. Were you at 60-65?
