which coil is best for getting close to metal posts & fences silver umax

[Gunnar of bradford MN]

just wondering would the 4" coil get closer to the metal posts or would the 5.75" be better would like your experiance befor i buy one

I'm wondering if a wide scan with the ability to detect at the edge of the coil might work better.

The closest I can get to a post is approximately the distance from the center of the coil to the edge of the coil. So the smaller the better. But a wide scan may work better, I don't know.

I can get closer to some walls. Both concrete and steel. It requires a technique. It's not very reliable, but I use it because I'm stubborn.

I am interested in anybodies thoughts on this.

turning the sensitivity down also will help. It has been my experience that the two coils you mentioned would produce a similar result under the conditions mentioned.

First of all, I do like Pap suggested...turn down the sensitivity a bit. I dont change coils. I use the 8" that is on my detector. The key is not to scan along side the pole or fence. Make perpendicular swings to the object. Then listen closely. If you dont have a target, you will get one solid beep. If there are other targets, you will get an extra beep or pop. I will use a medium speed sweep. Too fast and you will drown out the secondary beep with the main one that you are expecting. Too slow will pretty much do the same thing. Then I change my angles slightly to pinpoint. But i have been able to pick up targets close to the poles in a tot lot or change next to a fence. Of course a smaller coil helps too, but it isnt always necessary. Experiment a little. Try to see what works best for you. Use peoples ideas as a starting point, then adjust it to your style.

I use rentasquid technique and get a quickie double blip before the primary overload caused by a post, or whatever is the obstacle.
All told, a smaller diameter coil would probably get you closer.

i like the 5.75 coil, the 4 inch is really a small coil. and when i'm detecting close to fences i do as said i turn the sen. down. where i hunt there is allot of trash in the ground and allot of iron play ground toys. so keeping the sen. down and using a smaller coil helps. keeping the sen. down also helps in separation, and pin pointing. after a couple times at a certain place you will learn what works the best.

The smaller the coil the closer you can get. Lowering sensitivity helps also. A variation on Rentasquids tip is to place the tip of the coil against the metal and then drag it back semi-fast. If you get a double blip it's usually a coin or other target.
