It's something you will get use to. A silver merc came in as 88 ,same as a quarter, sort of feel like you should never pass up digging a 88 id.This machine is so easy to use. Dilek posted this about gain for the racer in an older thread ffrom another forum,I thought it would be worth posting here again for those of us who use the racer.
"The electronic gain of the RACER consists of 3 levels to eliminate the internal electromagnetic noise and to adjust the saturation level. The electronic gain change points correspond to levels 39 and 69 on the Gain setting. In case of saturation, you may raise your search coil a bit or adjust the Gain to the lower electronic gain level. For example, in the All Metal and Two Tone modes, if the Gain is set to 70 or above and if saturation occurs, adjusting the Gain to 69 or 39 will eliminate the saturation. Similarly, if you experience saturation in the Three Tone mode, adjusting the Gain to 39 will be sufficient. Reducing the gain will not cause a dramatic decrease in depth. "
