Excuse me if I sound like some sort of lunatic, but in all the time I have observed this site (on and off for the last 12 months), I have never heard anybody discuss the Ace's ability to be able to discriminate between coins and and rubbish, while pinpointing a target!
I've tried to use the standard pinpoint that is on the Garrett's site. It doesn't seem to work for me.
What I have found to work, is the method posted here by John from Edmonton, on the 29 of April last year.Thanks John. This method, involves locating the target, then with the coil to one side of the target, hitting the pinpoint button and while holding it down, slide the coil from side to side till you can centre the target and then side the coil either forward or back toward you till the target disappears.If the the target is is the top 2 inches, then where it drops out is directly under the T intersection of the inner coil to the connection to the outer coil. It is DEAD ACCURATE!! If the target is deeper, (remembering that the signal shape below the the coil forms a cone shape) then the target will be proportionally closer to the centre of the coil the deeper you go.
Using this method today, and having yet another sad day as far as finding coins go, only 3 in 2 hours (even left the battery at home for my Pocket UniProbe, so I had to stop being lazy with pinpointing and pinpoint accurately) I tried some experiments. While hunting on this same oval a couple of weeks ago, I discovered that after getting ticked off with pulling up what felt like a million screw cap (these are on the same notch as our $1 and $2 coins) I chucked down a test coin and found that when pinpointing a coin, the signal would stop abruptly. When pinpointing a screw cap, the signal would want to hang on and fade rather than a sudden stop. Anyway, I carried out some further experiments today and found that this tends to apply to most junk targets, with the exception of twist tops which also respond like a coin, but is generally below most coins on the TID.
Using this information today, I decided to pinpoint a number of junk items. The reason that I did this, is because most of our nickel plated coins fall in the same range. As a result, 2 of the three coins I found today, were in fact reading as junk items on the TID, but in pinpointing them, I could tell strait away that they were indeed, coins!! This I did with 90% certainty of them being coins!
THIS IS A MAJOR ADVANTAGE OVER MOST OTHER MACHINES IN THIS CLASS OF DETECTOR!
I don't pretend to be overly experienced, with about a total of 400 hours detecting on 4 different machines, but I have not come across a machine that is capable of this form of discrimination. With only 30 hrs on this machine so far, I feel that I've still got a bit of learning to do with it, but are these sort of abilities just seen as a given, and nobody ever bothers to comment on, or is it something that is generally not known about.
Thanks for any comments.
