I think its one of the easier machines to use. I always use the Relic programme and then modify it to suit the site.
Many adjustments you will never use or use rarely.
You can set the audio to suit your hearing then never touch it again. VCO pinpointing you either like or not so its a choice you don't have to worry about.
Screen settings are another one off. Absolute value you ignore unless you buy the Bigfoot coil.
The inbuilt programmes, as with the DFX, are not good as they set them to work everywhere which in turn means they don't work best anywhere.
A beginner can just switch on and go then add adjustments as he goes one at a time and see the true effect. Just sensitivity tweaks gives a good machine, dig a little deeper into the adjustments and you have an excellent one.
An established in ground test bed does help despite what one self proclaimed professional says " I do not own or use a test bed ....these conditions are totally false....the true test of a detector is in proper detecting conditions" Norfolk Wolf (Treasure Hunting November 2006). Now relate that to the accepted truth that maximum sensitivity does not always give the best depth (similar to headlights in fog... dip the lights, see more). If you don't know whats in the soil how do you know what effect your adjustments are having ?
