I have used quite a few metal detectors with notch capability and most of them seem to have a real big notch for nickels. That means you are digging a lot of trash along with the nickels. The CZ series is about the best I have seen at finding nickels without getting a lot of trash. I realize that no detector can only find nickels but some are a lot better at it than others. How do the Garrett machines do in this area?

How is the nickel notch on Garretts

Bill,
I've used several notch machines too. On all those machines I would find nickels from below to above the actual nickel notch. On the Ace 250 I can eliminate some trash by using the PP mode. But still get fooled by beaver tails and some square tabs. Even on machines with 95 positive numbers your nickel will still hit in a range of numbers. This is the same size window as a notch. In the ground everything changes.

In my field tests, it will just ignore the round foil thingies on the inside of juice bottles, but will easily pick up pencil erasers and the square tab that registers normally in the nickel notch. The canslaw and such give short, quick signals while the nickels and such give fairly broad signals. One nickel on the surface actually sustained the tone after I had moved the coil 4". I use the duration and quality of the signal to help out.

When I first started using my 250 I could not find any nickles. Everytime saw it ring in as a nickle it would just be what everyone else finds trash. However I have been testing some of the nickles that I do "have as loose change" including some "oldies" and others that I have found with the detector. You have to watch the icon close and if it stays on the nickle target it should be a nickle no matter what. If it deviates on one side or the other It will more than likely be trash but...I would dig just for the heck of it.
In other words if it hits dead on the nickle icon it usually is a nickle (or something made of nickle).
I recently went to an old 1920's house that had been added on to subsatantially and was not finding diddly squat so I headed for the drive way that was gravel. The owner (a old county judge of ours) must of just dumped all his change out of his car when he cleaned it onto the ground. I was gettting the coin tones ringing all over the place. and to make this short the nickles were coming up on the target ID of the 250 as nickles dead on and I was pulling them out as fast as I could dig through the gravel. I left with alot of change that day and it did let me know that the nickle icon works to a "T".

On my 1500, if my memory is correct, all the nickles I find hit exactly on the "4" notch. This may be a very bold statement but if I have ever found one that didn't hit on # four, I can't remember it. And ofcourse as mentioned, the pencil eraser and the rectangular tab will very often hit on #4.

Although I live in Australia, our 5c and 10c pieces hit in the same area as your nickels.
Something that I was noticing just before I sold my Ace, was that square pull tabs seemed to always give themselves away by bouncing by at least the fifth pass of the coil over the target, were as the coins tended to stay on the same notch. Our 5 cent pieces are smaller and had an increased tendency to bounce around a bit compared to our ten cent pieces, but if the target was still on the same notch after 5 passes, then you had a coin.
I operate my GTI in Jewellery mode, but notch out notch 4.5. Although pull tabs regularly hit in 4 as well as 4.5, if it is a pull tab, then you are going to get a fair bit of nulling as you pass the coil over it. You should be able to do this with most notching detectors, if the notches are narrow enough. One of the major identifying features of pull tabs, is their great tendency to bounce around, even the ones that have rounded corners. Coins tend to have a more solid sounding tone, but hearing that is less obvious than the bouncing around.

I know I have to be ether right on or one notch next to it. GTP 1350
I believe the nickel notch on the ACE 250 is pretty darn accurate now that I have been using the ACE for about a year. I've found the nickels seem to give out a very distinct tone variation. Other things that may ring in the nickel notch don't give out that tone. I hear that signal and go "now that's a nickel", and 98% of the time it is.
