Got my 5.75" concentric coil a few days ago:detecting:

[tabdog]

to use on my Cibola.

I've been out some with the 5.75" now and I don't mind telling you it's wonderful.

The only thing I've used it for so far is playground hunting and I couldn't believe the depth I was getting. I didn't know you could get that kind of performance out of a small coil. I have a 4" coil for my quick draw II and really like it,but the 5.75" is a hole nother ball game.

Today I took it out to my test garden. I don't know if any body will believe this, but I got a fairly good response on a quarter at 7". I could get a signal on a nickle at 7" but it was so week it would hard to catch in the field. I could also get a signal from a copper penny at 7". A dime at 6".

Does this sound believable? Am I crazy? Has any body els had that kind of performance out of this coil?

I'm almost afraid to make these claims because it sounds like bragging. But that's how it is whether you believe it or not.

The only thing the 8x9 has over the 5.75 is coverage. I still like the 8x9, I just have less places to use it now.

Keep er goin

I ordered the 5.75" concentric for my Cibola too.

I've read posts on this and other forums that say that coil gets great depth.

How is the pinpointing compared to the 8x9 coil?

How's the weight. Is it much lighter than the stock coil?

Yup - and that 5.75 coil gets more use over the stock coils on my machines. Deep and works the trashy better than stock. Stock covers more ground but that 5.75 gets to really working in on some areas. WTG

I think you will be pleased, unless you're just real hard to please.

I'm happy just to have something that works like it's supposed to, that's rare. The 5.75 exceeded my expectations.

Yes, it is easier to pin point. I've already become so casual about it in just a few days that some times I miss a little by not paying attention.

It is very thin and light. It reduces weight at the best place, at the front. It's not a whole lot lighter, the 8x9 is fairly light too. But it shortens the over all length and balance of the whole front end of your detector so it's noticeably easier to swing. That's important to me because I've had terrible MDer's shoulder. So bad I couldn't sleep. Had to stop MDing for a day or two.

I hesitated about buying one because I already had a 4" coil for the other MD. I'm very glad I went ahead and got one. It works great for most of the detecting I do. I do some relic hunting, and other stuff which can utilize both coils.

For about $20 I got a lower pole which is indispensable when switching coils in the field.

I'm sounding too much like a sales person, I'm not. I'm just an old frt having a good time with his Cibola.

and then you will need new washers. They are hard to find around here. I've cut up plumbing washers trying to get something to work. Thoes washers are hard to accurately cut.

The nut or bolt can strip out. When it won't get tight it just starts floping around. Also Dirt and oil get into the space between the washer and the coil and the lower pole and that will also cause it to slip around. Different MDs have some of their problems with that area.

My Cibola has a good coil to lower pole union.

These problems usually occure because of over tightening. Most people don't over tighten until they are out and its hot or cold or wet or bugs bite or the swet rolls or the nut cross threads and then oh! sh@*%4#&$ da&%#@)& thing Why didn't I get that lower pole any way!!!!@! I should a spent the $20 D@!^^ thing!

Honestly It's just easier and adds to your enjoyment of the hobby unless you just enjoy messing around with that dredded lower joint.

Hope that helps

I think it's quicker and easier to change coils.
I also use Velcro straps for the coil cable straight up the lower shaft. Then wrap the coil cable on the upper shaft starting above the lock collar. Just easier for me and ditto on the nut/bolt remarks. And if your out in the field to do a change and drop one nut/bolt/washer part - well, won't happen my way.

I forget how many ways there are doin things

There used to be a lot more metal detectorist around here than there are now. The main ones I knew are dead. There aren't any clubs. The only place I know of that sells anything besides Bounty Hunter is a hobby shop and the only thing they sell is Whites. No body in the hobby shop knows anything about metal detecting.

There are some out there, and they keep me busy trying to cover up their holes so people won't think I did it. I've been so ashamed of what they did I just had to leave before people started associating me with them.

I've found I have to build my own reputation and as a retired surveyor I am friendly enough that I can hold my own.

Don't know what that has to do with them D*!#! rubber washers. I guess the point is I'm just used to how I do things. I haven't been reading this forum for very long and just recently got back into MDing. I'm an old ball headed frt now and I am enjoying the hobby again.


hope you get some good finds

I once lost a washer changing a coil, and I know it was my fault. Made the rest of the hunt a little frustrating having the coil flop out of my set position. I didn't have (find anything) at the moment that worked to keep the coil to shaft angle rigid enough to hold position. And I should have never attempted it in a rocky area. I lost that washer somewhere within the rocks on a levee where I was taking a break and changing coils. And I didn't have a spare washer with me. Lesson learned.
Now I just don't worry about anymore. All my machines with extra coils have lower shafts attached. Just makes it easier for me. Like digging a target hit with a trowel or shovel rather a stick. That's all.
