Everyone always post what they have found with there xterra's but never mention what coil they were using. What coils have you tried and liked and disliked and for what reasons? Everyone has different ground where they live so what works for you and in what state? Just curious and it may help some decide on a certain coil they have been thinking about purchasing.

lets have some coil talk on this forum

I have tried a few different coils on my xterra 70. The 6 inch dd hf, the 5x10 dd elipitical hf, the 10 in dd mf and the stock spider coil. I have found that the dd coils are much harder to pinpoint with on the xterra and the pinpoint function does not really apply to there use, its just for concentric coils. I think the dd's are great where you can dig a larger hole to retrieve your target like at a beach or relic hunting where you can use a shovel. I like the 5x10 eliptical in trashy areas because of its narrow blade footprint. I live and hunt in north alabama and our dirt here can be the red dirt, chert , or field dirt. It seems the popular fill dirt here is either chert or red dirt so you can go from low and high mineralization very fast even in the same yard or vacant lot around town. I have found the 8 inch mf spider coil works ok in all of it. I am hopeing the 5x10 hf dd will work ok on the beach for me when I make it down to panama city florida this spring and I will try the 10 inch dd med frequency also since I can use a beach scoop to dig targets with and pinpointing does not have to be exact.
On the 5x10dd eliptical its very easy to bring the coil back and get the target to the tip and its there but on the 10.5dd it has a fatter blade pattern it seems and it also has more detection area along the sides and I have a hard time when there is multiple targets under it keeping the main target isolated and bringing it to the tip like I can with the elliptical.
The main point is under the label at the front of the coil, assuming you haven't mounted it backwards to handle the weight. Are you familiar with the idea of sliding the coil back until you lose the signal? Then you go at it at a 90 degree angle and do the same and it will get you down to fairly small area. If I remember right the FAQ in this section of the forum has a video on pinpointing with this coil. This coil is not designed to be used in a real trashy environment. If you're in a real trashy environment and trying to coinshoot you'd better off with the 6" DD or concentric coils. I use my larger DD coil to try and find Civil War sites and hunt for the deeper signals. When I get into a trashy Civil War period site I go down to the stock coil or even the 6".
You know that is a tough one, almost like comparing apples to oranges. In a purely factual way the concentric coil is deeper, however (and I do mean however) the deepest penetration point of that concentric coil is so small its real easy to miss targets at that ultimate depth. What it does allow is better seperation of targets at that depth than you get with a large DD coil. The DD coil doesn't miss much at its ultimate depth though, because of the wiper blade like pattern it uses, instead of the upside down cone you get with the concentric. I'm finding out that each coil has its strengths and weaknesses and having more than one coil in your arsenal is a real advantage when you're willing to swap out as needed.

Just got my 10.5 dd mf coil it sure loves bottle caps.
It will ID them at 42. I am brand new to metal detecting
but found this coil to pinpoint very well.
The method I use is to pull back towards me
until i lose the signal then i use pinpoint and get the strong tone
and the target is usually under the mine lab sticker

I only use the stock coil now. I have tried the 10.5 MF many times and it is heavy, locks on to bottle caps and has not proved to be deeper than the stock. I have hunted in the same area now for about 20 hours total, using both stock and 10.5 DD and I have not found a coin with the 10.5. The stock coil has found me 10 medieval coins, 2 Arabic coins and a 1600's coin (same area). I should have bought the LF 9' instead of the 10.5 DD. I can go 4-6 hours on the stock coil and not break a sweat but maybe 2 hours with the 10.5 and I am spent from digging bottle caps and the weight of the coil. The way I see it is though the 10.5 covers more area in one swing the stock allows me to hunt much longer, hence covering more ground.
I have the stock coil, 5 x 10 eclipse, 6" mf, 6" hf, and I like the 6" mf best of all. I know I'm not as experienced as most of the people on here, and I'm one of the few that really likes the 6"mf. It's just been my experience that in the places I hunt, the 6" mf works best for me. It seperates well enough and pinpoints exceptionally well. It also lets me ignore the iron in the ground better than the 6" hf. Having said that, I also enjoy using the 5 x 10 on the beach for ground coverage....it doesn't go as deep as I would like, but ground coverage, plus the relatively light weight, makes it fun to use.

I have the following coils:
Stock , 5x10 elliptical 18.75 kHz, 6" 18.75 kHz DD, and 10.5" DD 7.5 kHz.
For the type of hunting I do, the little 6" coil almost never comes off. It is typical for me to be the last guy on a site looking for "left-overs". It is amazing how well this coil will separate a good target and piece of trash that are right next to each other . I have found a few good coins that I'm sure were ignored because of how they sounded under a big coil. It handles mineralization well and can be run at high sensitivity in most cases. Up for argument..., but I feel you don't lose too much depth with this coil.
For the big lots with less trash, I do like the 10.5" DD. Covers a lot of ground and can get a litter deeper. Have had to dial the sens. down a few times to avoid chatter.
For parks and schools, I often go to the 5x10" elliptical. I like how much ground the coil covers and how hot it is on coins and rings.
Stock coil- Can't remember using it lately but, it is a great all around coil and will serve any Xterra user well.
Just one opinion...
1/2 way to Spring!!!! HH to everyone.

As I've posted many times in the past, the 9-inch concentric at 3 kHz is a silver killer. It is my go-to coil when searching old homesites and open areas. I hunt in all metal, multiple tones. Not only does it ring in "loud and clear" on silver and copper, it also provides a very distinct audio on that pesky old deep iron. If you do a search of my posts, I'd guess you can find a couple dozen or so where I brag on the benefits of the 3 kHz. HH Randy
I only have the 10x5 dd and the stock coil my hunting grounds are very mineralised and i find the 10 x 5 to be far better . Ground was so hot last week where i went to an old town that hardly exists anymore that the detector was overloading on the soil mineralisation alone . hence didn,t find much at all . Was hoping to get a few older coins but will have to try a different town. Problem is the next closest is over 200 kilometers away.
