Coin metamorphosis

I've had my coin finds building up for the last 18 months and had an itch to buy the GTI 1500. So that's what dopey did.:(

I bought the GTI earlier in the week and now have 3 hours of practice and 9 hours of hunt time on it already. Unfortunately, I don't think that it is in any danger of replacing the Ace yet, as the Ace runs rings around it for identifying targets though it's 12 notches and pinpoint mode. Hopefully that will change with experience. What surprises me most, is it's inability to give an indication of our 5c 10c 20c and 50c coins. only 3 of those have shown up to date, and 1 of those hit around 7, which is where our $2 coin comes in at. Unfortunately, non of our modern coins gives off a bell tone, and testing our pre decimal coins bounce all over the place and don't lock on very well, sometimes not at all. At least the Ace will give our $1 and $2 coins a bell tone (they both come in at notch :geek:. On the GTI they come in at 7 and 7.5 (when they don't bounce around).
Here are a couple of photo's of hunt 4 and 5. Hunt 4 has by far been my most successful with $32.50 recovered. What is interesting, is that the long bit of scrap metal locked in as a size B target. Somehow, I think that it was telling me a whopper.
Hunt 5 ended with lots of pull tabs and 1 $2 coin. The amount of pull tabs that I've recovered with the GTI has amazed me. Hopefully I'll get this machine to talk to me yet, but to date, we're not on talking terms.:(:lol:

nice 1:thumbup:
 
Nice pile of coin Mick
 
Mick. I had less experience (in months) with my Ace 250 when I did the same thing. My few hunts with the 2500 (practically the same machine as 1500 in discriminate mode) I was wondering if the extra $500 bucks or so was worth it. I gave it time and now am extremely happy with my trade up. Now, I find it very difficult to go back to the Ace 250. I find things quite a bit deeper. Pinpointing is a lot easier and more accurate. I really like the extra notches even though at first it was very confusing. Imaging is the big one. I still dig an occasional flattened can but that is very rare now.

It is too bad your modern coins do not ring up on a bell tone notch. That would be hard to get used to for me. It would be nice if you could program what notches use bell tone. As to why it's jumping around I have not experienced that. What are your pre decimal coins primarily made of? I know you have a lot of experience with the Ace 250 and have probably tried the obvious fixes. How does it air test? Do things indicate steady? How about silver coins?

Imaging is good but not perfect. I find that long targets are the biggest problem just as you did. Also the deeper you go the more inaccurate it becomes.

I hope it works out for you. You gave me A LOT of great advice since I joined here! Good luck.

Chris

I just looked it up. Your modern coins are very similar to ours here in the US in composition. 75 percent copper and 25 percent nickel, right? You dollar coins are similar to ours as well. Your coins should be ringing up in the bell tone area. I'd email Garrett and see what they have to say.
 
I found a 1969 Australian Half Dollar in my foreign coin pile. Indicates strong 6, very steady, at 7 inches with sensitivity set at 8. GTI 2500.

Thats a great way to spen the earlier finds.
 
You'll do better with lots of practice. The 1500 has a learning curve and it is programmed to ID American coins only.

I save them and give them to guy at my local Moose Lodge, he saves them for Charity:detecting:
 
Hey Mick nice post mate, that sure is a nice pile of coins!:clapping: I wish I could keep mine instead of having to spend them all. Still the bread and milk they buy goes to a good cause, my family. Hope you bond with the new unit soon mate. Talk to you again soon, HH regards Nugget.:detecting:
 
It sure would be great if you can select specific notches to belltone that don't at the moment.
Garrett's have set a high bar, to build a better detector than the Ace. After playing around with the Ace a bit on the week end and rechecking it's fading pinpoint discrimination, it's going to take something quite remarkable to better it. Everybody has said how much better the GTI's are over it, so with another 20 hours or so, I hope to figure out the imaging and see for myself. I think that I've made the mistake in thinking that it would be more similar to the Ace. That is probably the source of my frustration. It looks like a fresh approach is needed to overcome this. I've backed off the sensitivity from 8 down to 6 and this seems to have calmed the machine down.
Congrats on finding the 50c coin. I bet you were surprised at how big they are. Our decimal currency came in in 1966, so your find is of one of the early ones. You should see the range of 50c coins now, there is an awesome range of over 50 of them now, with all sorts of beautiful designs on them. I try to include photo's of the non standard ones as often as possible, for this reason. Prior to 1966 we had what we call our pre decimal coins (pounds, shillings and pence). It was based on the English money system. Some are made of all copper, some of the newer silver ones are 50% silver, the ones pre 1946 are pure silver, and we even had a couple of gold coins as well.

G'day Nugget. Yeah, there's around $1500 in the photo. 80% found with the Ace. I wouldn't mind living in your part of the world. I considered it for a few weeks a couple of years back. I reckon that for the same amount of time, that pile would be twice the size. There's around 340 hours worth of detecting in that pile.
How's the Infinium going. You would be one of only a few blokes that I know that get to harness both of it's specialties.
I think that I'll bond with the 1500 soon. Kinda like having kids. Sometimes you can bond straight away (not very often) and sometimes it's just a matter of time. That's not the most fun time, but it looks like I have may have nobbled that process by preconceiving that it' wouldn't be too different than the Ace. End result, lots more frustration than I expected.
Hows you school hunting going?
Mick Evans.
 
Thanks for the tip about using the signal strength indicator to pinpoint with Bill. I had a second source confirm that that's the way to go. I spent a couple of hours on it last night. It sure does take a lot more concentration than how I pinpoint with the Ace. I even tried it with the Ace. Once I've got that sorted out, it will be interesting to know if there is other target info that can be gleaned by this method of pinpointing.
Sorry if I seem to be a bit hard on the GTI, just going though a rough patch. Hopefully we'll kiss and make up soon (strictly metaphorically speaking of cause).
Mick Evans.
 
I didn't find the 50 cent piece detecting, it was given to me. My close friends know I love foreign coins and often bring me back examples. This was from an Aunt who went to Australia in the early 1970s.

Pre decimal currency of the British Empire is confusing at best. I have a lot of old UK stuff that I find in boxes of memorabilia from WW2. Once in a while I get some stuff from the pacific theatre or occupation currency. I got some New Zealand bills a few weeks ago with some of the large pennys. Also two 1930s half crownes. Beautiful silver coins.

I really hope the new detector works out for you. I tried to say in my post exactly what you said. The detectors are not all that similar though there are similarities. The only thing I like better about my Ace 250 now is that it's lighter. That is not to say it isn't an excellent detector, merely that I like my 2500 more.
