The way I pinpoint is different than everyone else.But I offer it so maybe you can try all methods and decide which works best for you.
When I find a target that I feel is a good one.I circle the target a full 360 in the regular detecting mode,not pinpoint.If there are two targets close together,this will help you center it pretty much.When you circle the target like this it for one helps you decide if the target is a good one and repeats from more than one angle, and it will narrow down the area quite a bit.I would think that part is standard practice among everyone,now the next part is where I differ.
After I have it narrowed down and I am sure I want to go after it,I raise the coil and push the pinpoint button.Lower the coil to the area you have it narrowed down to,making the first part of your x <b>with the little raised dot on the center of the coil.</b> When I have that part of the x for sure centered,I turn 90 degrees and repeat till I have the X centered using the raised dot as the point of the target.What makes it difficult is when you have multiple targets close to each other.That is where the circling and narrowing it down first helps.If you have the general location in disc down but are having a hard time getting it to pinpoint where you think it should be,then you have to work it.Some times you have to find just the right angle of the dangle to squeeze a pinpoint out with multiple targets.This is,IMO,what everyone has trouble with,seperating multiple pinpoints.With time it is very do-able.Let me also mention,if there are no other targets around,and your pinpoint is just not where you think it should be,it is usually a rusty nail.
I can't stress enough,no matter what procedure you use,take your time pinpointing,till you are confident your target is under your mark.Contrary to popular belief(Dave's,he saw the 3 silver coins I scratched out of 70+ so far this year)I can pinpoint and hit my target first try with a probe if I want to.The only time I am off is when I don't take enough time pinpointing and rush it or it is a coin on edge or it is a nail in the side of the hole that fools me.
The X-1 probe is a must!Even when you get pinpointing down,it still is awesome.I would not want to detect with out it!
