Coil Advise

[whitestar55]

Hi, My name is Rick and I'm from central/southern IL. Today is my first full day od ownership of a new Silver Max. I like it real well so far. I am primarily interested in coin hunting. I feel that this machine with it's standard coil will be fine for hunting most sites I will hunt. My question is for those older sites which coil would be a better choice for coins to get a little more depth?

Welcome to TNet Rick.

Glad you like the Umax as it is one fine detector. The standard coil is great for most sites and you will get more targets by overlapping your sweeps by at least 50%. The older sites don't necessarily mean the coins are deeper, but there will be more trash to contend with. I suggest as small a coil as you can get for better identifying the good targets from the bad. The standard coil could get two or more items under the coil and it could disc. out enough to hide the good signal. Hence the use of a smaller coil. When you have a huge area to work and need to cover it fast, get the Tesoro Clean Sweep coil for your detector. It's great for beating the completion to the goodies.

Good Luck,
Sandman

I'm looking for maybe 2 more inches in depth when I'm searching old homesites. Would a larger coil give me that?

I use a 3 X 18 CS coil on my Tesoro.

It is GREAT for a speedier attack on a large field.

I do NOT feel it will find deeper targets than the stock 8" concentric.

The 10 inch coil will get deeper and see more ground that could have trash in it. Disc. out the trash and the detector won't respond to a good target underneath unlike a Minelab.

Better depth? Get that 12x10 concentric coil.

Right now your Silver with the stock coil will consistently get 4-5 inches on a dime in undisturbed soil.

Put the 12x10 on it and you'll get 5-7 inches depending on soil conditions.

But the larger the target the deeper the gain.

You're most likely getting 6 inches on a quarter now. With the 12x10 you're looking at 8-10 inches.

Gold rings now 5-6 inches. With the 12x10 easy 9-10 inches (Tesoros love gold).

The problem is the 12x10 is heavier and makes your Silver off balance. I don't mind it at all but some don't like it.

I have off and on used the 12x10 in places where there is a target every 2 inches in the ground. Mostly pulltabs, foil, tin, rusty nails. I had no problem separating coins out from the trash.

My theory is all the Tesoro models get close to the same depth if fitted with the same coil. I think they put that tiny coil on the Compadre and that 8-incher on the Silver, etc., so that in coin garden tests buyers will think each is progressively deeper due to the electronics. It's sort of a marketing ploy to sell multiple models. All the companies do this in one way or another.

Hunt slowly with the 12x10 coil just above the ground. I found that setting the discrimination on the zero in FOIL works best for me. Iron will break up unless it is deep. Dig all signals that hold solid and tight (small in size). Sometimes I just wiggle the coil and raise it slightly. Remember, with concentric coils you have a CONE shaped signal. Raising the coil is like a free small coil
