1. Test targets? Try also using aluminium - melt some drink cans and make some targets. See the latest GG&T for why.
2. Swing speed. This is applicable to the 10 x 5 on an older VLF like the 70 and the 705. Rule of thumb - 7 second swing per metre, belt along and you will miss SMALL targets using a small coil. Bigger coil, naturally the swing speed varies as does the application on quiet ground. This speed is the result of a hell of a lot of testing in the introduction phase of the Xterras. I am not talking about a beach or park - but mongrel mineralised and red clay infested goldfields.
3. Sens - IMO the threashold should just be audible - you are listening for very soft breaks for small targets.
4. The made in USA instruction DVD that comes with detector? If detecting for gold in Australia, especially on the mineralised ground, take DVD, open case, take out DVD, thrown on fire, burn DVD - it will be of more use.
