She auto gb, no matter where you are. I think its actually 3 settings that switch internally, but don;t know. Start by getting settings correct. Order a plugger straight shaft, if it needs warranty work send back in stock shaft.
Sensitivity as high as it will go stable. Disc, lowest possible. Iron makes machine go silent. I dig everything.
I also have rtg style scoop. 7" ss. Good for most conditions, except rocky areas. I think rocky spots are just hard anyway. PM me about scoop if you want one, although I am in ma an will not ship without payment first.
If you got a minelab duffel back with it, be very careful. It does not protect the machine. Don't drop it, at all. Don't leave it laying in sun. Don't let pets get near it. I am the only one who touches mine. You will need to do a few things to maintain it.
It breaks down easy enough for storage. Get silicone spray at a dive shop. Apply after every use on all cables. Gently remove coil cover when done, an clean sand. Gently. Do not epoxy coil cover on, sand still gets in there. Some cover with truck bed liner, thats pretty much ok. I usually charge battery 1 for 1 with use. Give or take. 6 hour hunt means a minimum 6 hour zap. Overcharging will fry battery.
I can't think of anything else really. Scoop I have is really nice. There are also lots of freindly sponsors that make different ones, mine is RTG. They all I use. hh an gl. -Joe
