Pinpoint and bottle tops?

[Mick in Dubbo]

Hi All.
Just wondering if anybody can tell me if you can tell a screw cap from a coin when you pinpoint. I've heard a lot about how good the tesoro's are at pinpointing, and thought that this might be an ability of it. I currently own an X-terra and an Ace250, with both these detectors can give varying degrees of success, when trying to figure this one out.
Thanks.
Mick Evans.

I have a really hard time differentiating between screwcaps and coins. They are so close to the same sound, only a little louder and stronger. I dig my fair share. I cant help you much with this one, because I struggle with it with my BIIumax.

Would raising the coil up help? Since they are mostly aluminum wouldn't they bang out loud from much further up than a coin?

I know I figured a way around those pesky foil and foam thingies form Gateraid and what not with the 250.

There is some sense in what you say saika. With the X-Terra's, a bottle top tends to give a loader pinpoint. On the Ace; about a third of the time, coins and crown caps stop sharply when you slide the coil over them in pinpoint; as opposed to a bottle top, which will tend to fade as you move off it in pinpoint.
I am interested in what the Cortes in particular can do, and was wondering how the Tesoro's handle bottle tops.

bottle tops are one thing. Screw caps another. The crown tops, I've not had problems with, because they tended to be more crackley. The screw caps sound like a coin. And, I dont check and recheck every target. If it sounds pretty good, I dig it. But they always fool me, because they ring out real nice like a quarter.

Thanks for the reply rentasquid. I have always considered a screw cap and a bottle top (coke lid)to mean the same thing. I was wondering how you define them?
Given this information; there doesn't seem to be any advantage with the Tesoro's to help out in pinpoint.

Mick, what I was thinking, is that I typically find two types of caps. One would be the aluminum ones that screw onto a glass bottle of your favorite beverage. Those are the ones that I dont have much luck discing out. The other type are the ones that are pressed(crimped) onto the lid of most adult beverages. Those seem to be made of steel or some alloy like that. Those are the ones I have no problem with. Then there are pull tabs, but they are a world of their own. Hope I didnt confuse you any further.

That is right the pull off soft foil foam type give a fat rounded out sound with a lot of low end audio, not to be confused with a low tone. The aluminum screw cap type like off of a colt 45 malt liquor bottle tend to stay loud a lot longer that your average coin, as you lift the coil. I agree with Squid about them sounding like a quarter, up here they sound off like a one or two dollar coin so I gotta dig them up also. Some of them do disc out at a specific point on the dial, but it is well in the coin range. Crown caps have a fairly wide pinpoint, usually as if they have an iron component to them, and they do crackle around the edges especially if bottom up or a bit rusty.

Yeah. Them screw caps are a bit of a pain. Our Aussie $1 and $2 coins discriminate around the same area as US 1 and 10 cent pieces. I reckon, that when the US mint finally decides to go into full production of US $1 coins,; I'll lay odds on it that they will fall into the same area of discrimination!
All the input has been quite helpful.

Screwcaps are big homogenous pieces of metal. THey react accordingly.
- They will signal over a large area in pinpoint. Coins are defined and concise, on the other hand.
- As you lift the coil, they stay with you longer than a coin will.

I've heard a lot about how good the Tesoro's are at pinpointing, and thought that this might be an ability of it.
Tesoros are pinpoint stars, no doubt. MUCH easier than that ACE, Mick. Will they solve the "problem" of screwcaps? Nothing will. Learning how each unit reacts to them and knowing that respone instinctively will help.

PS Just for the record, one of my favorite gold finds, a big, heavy handful of solid gold front teeth, rang in smack on the screwcap point - in a park littered with screwcaps. Draw your own conclusions, mate.

Find any bones with those teeth?

Thanks Dave.
The info is helpful. I think that once I have enough to afford one, then it will be time to take a long drive to the dealer and give them a closer inspection. If I'm parting with that mush cash ( detectors over here are twice the dollar amount than you guys pay) I want to be able to use it first.Always bought by mail order, and it's a bit of a lucky dip.

...Ill predict that there are things about the Tesoros youll like and things you wont by comparison to the others you have.
