Question about the 250's large coil.

[Mick in Dubbo]

When using the Ace250's large coil as opposed to it's stock coil, do you tend to pick up less rubbish due to it being less sensitive and does it miss a noticeable amount of coins through masking(due to a larger footprint)?
Thanks

All larger coils are goning to produce more of a masking effect. It again depends on where your hunting. If I was at at beach I would use a bigger coil, in a farm field I would stick to stock. In a trashy park or any trash site the smaller coil for sure.

It won't miss any coins. And it is very sensitive too. I quit using the stock coil after the large coil arrived. Now it's only the sniper or the large coil that I use. If you like hunting sports fields, get the large coil. But.....if the fields are just loaded with trash, the stock or small coil work the best.

I agree with John. I recently purchased a large coil for my 250 and really like it. I have used only the large coil and sniper since then. I hunt mostly athletic fields and kids playgrounds and the large coil really works well in the open spaces. I then switch to the sniper for the tight spots such as around bleaches, benches, fences, the various metal playground structures, and trashy areas.

I got to use the large coil at a Cape Cod beach this past weekend and it sure didn't miss any of those almost microscopic pieces of tin foil floating in the sand. Sensitivity will not be an issue.

I do feel that the large coil is noticeably heavier on the detector but not bad at all. I also thought that it falsed a little more on uneven ground than the stock coil but cranking the sensitivity back a notch cleaned it up. I'm glad I bought it.

It's far from being less sensitive and it doesn't miss much.

Thanks all.
Kind of hoped it was a bit less sensitive on the small junk so that you can breeze right over them without affecting them coins!(some of us are never happy) Anyway, it should make it a good little unit for jewellery hunting at the beach.
looking forward to getting my hands on one of these fellas as soon as I can afford one and become part of the Garrett family. In the mean time, I'm going to enjoy the toy that I'm playing I've already got and be a bit of an interloper on the forum
Thanks for the insight

If it's less sensitive on small items, it's not by
much. I've still found some very small pieces of metal
with the large coil. It basically acts the same as the
stock coil, except that the coverage is larger, and the
depth increases a bit. If you are in a "busy" area, it
can actually be more of a hassle weeding the trash than
the stock coil. Mainly cuz the coverage is larger and
it sees more at one time. Pinpointer masking can become a
problem of the area is really cluttered.
But it is still quite sensitive to small objects.
I've found BB's, and even smaller scraps of metal with the
large coil. When I want to weed through junk, I use the
sniper coil. All of the coils have good and bad points,
depending on where you are hunting. Thats why I have all
three.. I prefer the sniper for trash weeding, but in an
open field that is not too busy, the big coil is the way to
go. More coverage,and about 2 inches more depth than the
stock coil.

Thanks MK.
Yeah. I'll get all three coils and the inline probe as well.The reason I asked was that I had been reading about concentric coils in general and the information indicated that at 15inch diameter the concentrics tend to do poorly on coin size targets.This seems to be about as you can go on a DD coil as well, but they seem to fair better on that score.Given that this is a 12in coil I thought that it would still do well on coins, but thought that it might lose some sensitivity that it might miss some of the smaller junk items = smoother running operation.But like they say: if you don't ask the question then you want know the answer.
