Coil Choice Can Make A Big Difference When You Are Comparing Machines You Own *For Yourself Privately* In The Field Just To Satisfy Your Curiousity

[Critterhunter]

I've recently read a few posts (no names, let alone model names!) of people comparing certain machines they own to each other. Often I see these comparisons are invalid, because they are using say an 8" coil or even a 10" coil on say a Xcal or GT for instance, while the other machine is using a coil that is a bit or even a good bit larger in size.

So keep that in mind when you are *privately* (to satisfy your own curiosity) comparing your machines to each other in terms of depth or even separation. In terms of depth, with two somewhat similarly capable machines, the one with the larger coil generaly wins. And of course in terms of separation a sharper detection field, or of course a smaller coil, will often do better...Even if the machine you are testing it against has a much faster recovery speed.

Just some thoughts to keep in mind as you see what your machines can and can't do for simple curiousity sake *privately*. Largely, in a good capable detector, such as Minelabs, the real edge on depth or separation goes to the machine using a bigger or sharper (or smaller) coil. You've got to try to at least compare apples to apples and oranges to oranges *for yourself privately* in terms of similar sized coils to each other. I know the 12x10, with only a 2" length difference between it and my 10" Tornado, is showing much better depths in my soil...even though both coils are exactly the same size in width.

Before considering upgrading one of your detectors, and that includes any detector from any company, find out from others what a good aftermarket coil might do for it in terms of depth and separation...To the point where you don't really see a difference between it and the machine you were comparing it to. A good aftermarket coil can make all the difference, and is a much cheaper alternative in some situations than upgrading your detector.

Critter i like those comparison videos on You Tube i know what machine your talking about i seen it in action my self on the beach , the coils used where only a 1 inch difference . What i saw on the beach was not that video but a actual hunt in wet sand a 14k Lady's thin wedding ring was found at 12 inches with a 11 inch coil my Sov GT barely picked it up with the stock 10" coil Here is one of those comparison videos Jim .

Jim that is impressive. Thats I think the 2nd vid Ive seen on that machine and can understand why people would want to give it a try.
Targets get swallowed up in the sand quickly at the shore here(NJ) and depth is real important.......plus that sensitivty to the small stuff is really impressive.
Thanks for sharing.

Deepdigger, nope....I wasn't refering to that machine. I know it's a depth monster at certain sites, but it does have it's issues too. It's more of a PI machine with iron rejection ability in certain respects, so great for relics and such in fields...But prone to EMI or even salt water interference, so not suitable at some beaches with nearby electrical stuff or salt soaked sand, and with no tone alerts or VDI also not suitable for parks. But for certain beaches and field hunting for deep relics or coins it sounds like a great option.

I was refering to a few posts in another forum, but I'm not going to mention machines or which forum because anymore I'm trying to turn over a new leaf as far as descretion on here as there are policies about that so I want to try to abide by them and "stay clean".
