For just starting out, this is what I would recommend for settings. Discrimination set at 1, Sensitivity at Auto, Volume all the way up, Threshold at a comfortably low hum, and hunt in Pin Point. Once you hit a target, flip the switch to Discrimination. If the sound then nulls, flip the switch back to PP and move on to the next target. If you still get a sound (even at a different pitch) dig it. Hunting in Disc might sound easier, but, you will notice that the threshold pitch will change with every target (both real and false targets) which can be annoying for many. Also, you give up at least 2" in depth hunting in Disc. Just be easy on the knobs, as the factory ones are junk. If you break any, get some good aftermarket ones with set screws and a slightly protruding pointer. The knobs are pretty stiff to turn, so, take note on which way they turn and don't turn them too fast or with too much force. You don't want to break the switch. Once you get over 100 hours in it, you can experiment with other settings to optimize it's use. Once it's out of warranty, I recommend a straight shaft with pod relocation or hip mount, bigger coil (if you have big, wide open beaches and/or not hunting predominantly under water), and the pin point modification where the switch is relocated to the handle. Then you'll join the rest of use wondering why they didn't come that way from the factory!
