I’ll keep this brief to begin with an add to it over time. The first thing I would point to is coil control. With this detector–coil control is the activator of all the other target info coming in. When you learn to use the coil to perform tests (sweep direction, length, speed) the results will be there in the audio and on the meter. Try some hunting in G2 with a low block rejected (0 to 6) to settle the audio down. Test each signal on the cross sweep and note how caps and anything odd shaped will “stutter” and hesitate. Smooth responses will be clean metals (not alloys or anything with iron / steel content like caps). Using this method has upped my beach accuracy by miles and at the most heavily hunted site in Canada–I now look for the areas with the most junk to pick though using this method. This is also a good way to learn to listen for responses with extension in the tone. The Equinox’s gold field quality noise reduction and iron rejection are amazing tools with some practice.
For more information take a look at my book: “The Minelab Equinox: From Beginner to Advanced.” available on this site. For those who already have it keep an eye out for the more advanced “Volume 2” that I’m currently working on.
Good Luck Detecting, clive
