[QUOTE="SteelPat, post: 288363, member: 4467"] If the mods are similar to others, then the higher the freq - supposedly better for smaller gold. Trade off is slightly lower depth. The gain control will basically control the input gain to the first or second pre-amp. If it were mine, I would set machine up with freq mid to high, gain mid way and set up rest as per standard manual. If its a bit noisy just turn the gain down a little. If the ground is a bit deeper and after larger nuggets, try lower frequency. [/QUOTE]
