I have some work to do to get my Racer 2 dialed in, but it's coming along bit by bit. The nice thing is that there aren't 1000 adjustments to make to get the detector to work. You can only go so far out of whack. and even then, the machine will STILL detect. So with some careful studying of the manual, some air tests to see and hear the different tones and going out in the field and seeing what comes out of the ground, I'm doing okay. My question is what is the recommended settings as far as Gain (I know it will vary depending on the conditions) and two tone, three tone, beach etc. when using the small 5" coil.. I turn up the gain to 90 when using the large coil but i think that will overwhelm the small coil so I dial it back to around 60 or so. People say that it's a crazy deep coil so I'd like to know what the successful people are using with it. I can't complain at all, I'm very happy with the machine, It's already found silver for me in a hunted to death side yard and today I snagged another quarter from the soccer field. I know if I refine my settings more, I will have better luck. I dug a lot of soda and beer cans today, (Our High School Kids are THIRSTY!) but they tend to fool even the "Sophisticated Three Frequency" machines from time to time.
