1 What is the best price that you can pay for this machine ?
Ask you local dealer for the best price, the worst they can do is say no. Then ask someone else. IF you get a better price don't tell anyone. For the record, I paid list for mine but I have gotten good deals on other brands. The least you can expect is that the dealer to keep all the "extras" and give you a better price...
2 Ground balance Do you have to ? or is it auto ?
You need to ground balance in All Metal "track" then switch to search? I keep my switch in "pinpoint" and hunt in disc, it auto ground balances in disc. Then if I pinpoint I just flip to "all metal"and it's already in "pinpoint". Some people search, at some places, in AM pinpoint because you can swing fast. Then flip to disc to check the target. Also, if you get a target in disc then when you pinpoint, it moves... it is almost always is... well it is trash.
3 Pinpointing Is it good on pinpointing how accurrate is it do I need a probe ?
Pinpointing with a Sovereign GT is EXCELLENT. I can pinpoint very well without switching to "pinpoint" but... if you switch to pinpoint it is a short, quick beep that is east to center and it is there. The E-TRAC for instance may lose the target when you go to pinpoint and you have to switch back to disc, acquire again then switch back to pinpoint... not with the GT. You go to pinpoint and it pinpoints! Now, you still need a handheld pinpointer to help you recover the target. Some people will take the soil out handfull by handfull and wave it in front of the coil and that works but it makes more of a mess and it isn't for me. I have an inline probe but I don't use it anymore. It just isn't as good as some others IMO. The Uniprobe is the deepest I have used and only pinpoints from the end of the wand, it will hit 3.5 to 5 inches. Right now I am using the Garrett pinpointer, it is well built and detects from both the side and the end. You don't have to get one to start with but you'll want one eventually.
4 Speed How slow do you go or can go ?
You cannot swing it fast like a T2/F75 or a Tesoro but frankly, you don't have to swing in "slow motion" either. You will miss deeper targets in trash or high mineral if you swing too fast but usually a decent target will make a sound. Ifyou're going too fast the tone may be a little past where the target is but, it's easy to find. You won't miss a quarter at 6" in regular hunting. If it is badly masked and you are swinging too fast.. yep, you'll miss it. That s why people like to keep a threshold. When the threshold drops out you stop and slow down and check it out. However in high mineral or a lot of little iron or iron ore... you can pretty much forget keeping a threshold unless you go slow in "auto". But don't worry about it, it is easy to figure out if you stay with it and ask questions. I can point you to a couple of people who will make you a pro.
5 The meter Do I need to have this ?
YES. You need the meter. The SovereignGT has probably the best TID in the business. It is VERY stable and will lock on. If a target is deep or small you get right on it and wiggle the coil back and forth, about 1/2 to 1"... really fast and the number will begin to rise. Sometimes if it is really deep it will try but wont make it all the way up to it's proper number and stay there. The tone will be there though and these two things together are needed. The tones are not just a pitch either, there are "round" tones and rough tones, there are high to low tones and low to high tones in AM which make the AM actually have a slight disc quality. I forget the exact TID number but somewhere around a nickel, in AM, the tone switches from high to low, to low to high. It is a nuance at best but a useful nuance. On gold and silver jewelry... it is amazing how it locks on to the number and tone... GT does stand for "Gold and Treasure". You NEED the 180 meter!!
6 Reliability How long did yours last before you sent it back ?
The Sovereign is a solid machine and I have never had a moments trouble with it. Not many people do. If you are not under warranty David Keith at dixie-metal-detectors.com may be able to fix it. He does modifications to them that make them perform better. He did some early work with Minelab and learned some stuff but he will not tell you what he does, he has an understanding with ML and he, being honorable, keeps his knowledge to himself.. his modifications are good. I assume since he can modify them, he can probably fix them unless it's something serious like a board. Much of this is purely conjecture on my part though. All I know for sure is that he knows how to mod them, can't talk about it, and should be able to fix them... not that you'll need repair. It is one solid machine.
7 The company How would you rate with service ?
Never had to use it. I have an Explorer SE, an E-TRAC and have had the GT for years. Minelab has been going through a few changes in the last year, moving some facilities and I think they may have gotten behind on some things but I am sure they will get things back in order. I wouldn't give it a thought. I have absolutely no apprehension about buying any Minelab detector, they are the Harley-Davidson of detectors. They seem to over build and you'll find their detectors to feel substantial. The Sovereign is not the lightest detector but if you are on grass it is so well balanced that you can let the coil slide over the grass, let the weight rest on your forearm using the top strap of the cuff, and swing it with a finger. If you're in the woods or on the beach the BEST solution is a binocular harness from Cabelas or anywhere, they are cheap and clip right onto the nylon box cover that comes with the detector. Then it is chest mounted and that solves every weight problem. I have disc problems in my spine and it is no problem for me either way.
David, mentioned above, sells a little "offset" mount for the meter so that it sets maybe 2" to the side of the shaft. That really helps you to see it better, it also tilts it up slightly and that helps too.
Did you ever get the V3 figured out? It is a hard one for me, the GT is much easier IMO...
