18X5 Double D Hi Freq. question

New member
I am wondering how this coil performs on coins and relics. I have the 7.5 concentric and it does`nt separate targets as well as a double d on my other detector. I am buying the 18X5 for gold and would use it for coins and jewelry and relics also if it is able to do it....Thanks.
 
Hi bluewing.
I assume that you mean the 5x10 high frequency coil.
I don't know about relic hunting, but for coin shooting, it is my favourite. Excellent target separation, the most stable target TID and gives you the best ability for the X-terra to feel your way around a target. And did I mention that it's lighter than the standard coil. About the only down side, it's not waterproof, so don't submerge it. it should handle damp lawn though.

Yes Mike I did mean the 5x10 coil. So many numbers and specs I got a little confused. I got the 18 right for the frequency anyway. After using the double d coil, you can see how easy it is to separate targets. I have one on the way. Thanks for the info!
 
Bluewing,

I just bought the 705 w/ the 5x10 18kHz coil and i will say at first i had buyers remorse. I say at first because i didn't know how to set it up. After leaning how to set it up (noise cancel, ground balance, sensitivity, ect...) i was able to find quite a bit. The first hunt was really stressfull. I set out using coins and treasure mode 2. I only found 1.54 in clad and a vintage Rosen lighter(still in great shape - going for 20bucks on ebay). I kept finding the little things like a lead fishing weight at 2.5 inches down, my first bullet, three wheats, a few odds and ends but nothing too great. The second time out,setting it up coin and treasure mode 3 correclty or at least based upon my limited experience i was able to find 5.74 in clad (13 quarters +change), a junk ring, bullet shell, some junk jewelry and other odds and ends. There were a few targets that i didn't dig for because they were too deep and the ground was packed in gravel, after 4inches i gave up. So, coin detection - no problem. I don't think it will have any problem finding relics, i tried the AM mode and noticed that there was a lot of iron everywhere so i know it will pick it up i just don't know what depth they will be at. I am still wondering about gold though, maybe my ring (10k) is not large enough (its not the size its the heart behind it) for it to detect it or i need to change settings but i though mode 3 was supposed to pick up on gold jewelry. Help from other members here would be good.
Good luck, HH
 
I have two family members and a friend that all bought the gold package that comes with that coil. I'm using the 10.5" HF DD most of the time. The 5x10 has proven itself to hang in there with the 10.5" DD and one occasion that comes to mind, they actually found some very old coins in an area that I'm positive I went over with my 10.5" coil first. We were detecting in some soil that was pretty noisy and I'm not sure if my larger coil was picking up and rejecting more of the noise or if perhaps they had a little better ground balance than what I did. this was one of the worst detecting spots as far as nasty ground that I think we have ever detected in. We were all hunting in the same pattern mode.

Here is a post that my brother, hotrod53 made the day after he ran circles around me with that coil. Don't get me wrong, I was happy for him to find these coins but I was kind of scratching my head being that I had a year jump start on him using the 705. I think detecting is sometimes like fishing, two guys in the same boat can have completely different levels of success at the same time in the same water. One day you'll do good, the next day the other guy will do good.

Don't sweat it, I think you will be happy with it.
 
Thanks for all the info and encouragement. I had no problem ground balancing and finding coins with the 7.5 concentric. It just took longer to root them out with this coil. I can`t wait to get the 5X10 DD coil.
 
great coil
90% on my machine all the time

I love the coil in my local parks it kicks coin but. I am planning on purchasing the 6" DD HF coil for the trashier areas of the parks.

That 10K Gold ring is large enough. Check the ring in AM and see if it comes in at an ID you have disced out. Watch the Tracking mode it can balance out good targets (you almost have to try on shallow targets) and if you check the ring on the ground you may already be in null. Some Gold hits exactly where pull tabs ID. Typically they sound better.

Such a very amazing link!
 
Don't get too hung up with running specific Patterns as each of them can be modified with a couple clicks on the pad. My suggestion would be to get a sample of each type of target you are searching for, as well as a handful of the trash common to your area. Wave each item under the coil using the All Metal mode and write down the TID for each target. Then go into a Pattern mode and build your own Pattern by accepting the targets you want to accept and rejecting those you are willing to leave behind. Note that some trash has the same conductivity reading as some of the good stuff. So if you discriminate out too many notch segments, you'll be no better off than the last guy who hunted that site.
