Here is the basic start/set up settings and cheat sheet that I have taped to the bottom of my vsat- should get ya in the ballpark.
Settings
G.E.B.- 5
G.E.B. fine-12 o'clock
Iron ID- set to center
switch set to right on SAT
VSAT switch (bottom of detector) set to off
Threshold - full counterclockwise
Start up
1. Turn GAIN up to 10 while holding detector in air
2. Turn up THRESHOLD approx. 4-5 turns until a soft hum is heard (think mosquito)
3. Lower coil to ground if no squeal -ok, if squeal turn down gain until squeal goes away
4. Ground balance- hold coil detector close to ground, pumping detector up and down (slowly), starting with G.E.B. coarse dial; if sound gets louder on the lift- turn to right. If sounds get louder on the drop- turn to left. Use G.E.B. fine to dial to fine tune.
If I adjust anything I re-ground balance, same goes for changing soil types (dirt to bedrock, or sand or red dirt to brown dirt- you get the idea). These are the very basics of set ups for the detector, I'm sure others have many different settings and approaches and mine may be totally wrong who knows, but for me these were the simpleist and provided good results. Good luck, the vsat is an awesome machine and will find anything a several thousand dollar machine can once you get the ear for it. Learn to trust it. The first time you dig down 4-5 inches and think there is nothing there but end up finding a sliver of a steel bristle brush you can't hardly see or a tiny boot tack you'll become a believer, it don't lie. The Biggest nugget found on our claim so far has come from a VSAT (unfortunately it wasn't mine, lol). The different White's goldmasters have also found more gold than any other brand detector on our claim and we have had some very spendy detectors and very experienced detectorists up there. Could be our soil type lends itself to the White's IDK. One last thing which I'm sure you have already heard - dig it all, ignore the iron id and just dig, some of the bigtgest nuggets ever found have registered as iron or trash. Last thing- a vile of gold will sound different than a nuggie, but your digging it all so that won't matter, right? You can tape or glue nice picker to a poker chip and practise with that to learn the sound.
