SE Discriminating depth...Try This....... :minelab:

[Texas TH'er "Georgetown"]

OK. I have been testing my new SE out for about 2 weeks now along with my ID Edge, Big Bud Pro, F75, Ace 250 and a few others. I have found something very interesting. I have a test plat with a silver quarter at 7" along with some other silver coins. Yes I know there is no "halo" effect etc, but I would like to share my test with everyone anyway. I just got the new 6" excelerator EQ2 coil and that is what I am doing this test with. By the way, Kellyco told me that the 5" excelerator coil has been replaced buy this new 6" coil. I've been using it and it's goooood. Really quiet and stable, LOTS LESS FALSING!!! Anyway, on the quarter at 7" the SE Id's the quarter as ferrous high conduct, far left top corner...CONSTANTLY...in all metal mode. So do my other detectors. I believe with the stock 11 1/2" coil it would do this after maybe 9" or so. I'm going to do a few more tests with the large coil and I'll post my findings. I read somewhere a while back that detectors don't discriminate "coin sized objects" much after about 6"-8". I'm starting to believe this from my experiments. Anyone else seen this? I would urge everyone to try this: Go out in your backyard and bury a silver quarter at 5,6,7 & 8 inches, deeper if using a larger than 6" coil. Try and detect them with discrimination and then in all metal. See where they come in at on the screen in all metal. You may be surprised. I would love to here about everyone else's results...Dickie

I can tell you the results fairly accurate and why. The results will not be as deep as if you are detecting naturally buried objects.Even if we throw out the idea of the halo effect, there is the deal of disturbing the soil when you put the coins in the ground. The ground has a natural matrix to it so when one digs a hole he has disturbed that matrix so the detector has more to deal with to try to get a signal.Yes, I do plant objects in the ground to test and it serves a very good purpose in testing detectors but there is a limitation on how much depth you can get when doing so...Still, let us know what you find out as it can be very useful.
Say, you have quite a list of detectors, how do you like the F75 compared to your other detectors?

Well I really like the F75. It's a great detector. But, I must say that I think a lot of detectors or great. A lot of people are talking about how deep the F75 is and the SE or whatever, but these detectors now days are coming stock with 11" plus coils. A few years ago 6" to 8" was the stock size. When I first started detecting these large coils were mainly just used for cache hunting. They were hard to GB too. I have found that if I put the same size coil on the detectors I've used, they all get "about" the same depth. The big difference I have found in the new detectors now days is the ability to handle these larger coils and operate smooth and much more stable than in the past. Don't get me wrong, I think that detectors have advanced a lot in the past few years, but mainly in features, not power. The FCC has set limits on the transmiting power of electronics. I will be curios to see what the F75 does with a smaller coil. I wish they would hurry and come out with one....Dickie

Sounds about like the same results I've found about depth. I like my old Explorer XS because it can keep up and some of the time surpass the depth of most detectors on the market, and it is paid for. I like the tone ID and meter as they are second to none also which is important to me in most detecting situations. Till somebody comes out that blows away all the competition, I will keep using it. The new kids on the block haven't really showed me that they are that much superior to what is already available, that is my take right now anyway but each to his own so hope nobody takes this personal

I have used a goodly share of different detectors and must say that there were always traits I liked about every detector that I tried and there were traits that I didn't like about them as well.

A silver quarter will always hit upper right on my Explorer XS.

Now then, if it is really really deep it will still hit upper right but it might bounce to the left toward iron but will always bounce back. If it is really deep it might not be perfect upper right but darn close.

My XS has never once had silver go solid upper left.

I would say that is probably the case, iron seems to be the culprit, my SE has never done that either, deepies do bounce but not till at least 8-9 inches and never repeatable high left iron.
