Why are my Coil Tec coils not working very well with my SE??

[digitrich]

I have (2) 15 inch WOTS, 1 new 1 used. The 5x10 Joey coil, and the 8.5 x 11 Platypus. I am wondering if anyone who also has an SE has had good results with these coils, as I, am not. I get awesome results with all the Excelerators SMALLER than the 14 inch and all three of the Sun Rays. It seems like the very large coils (Excelerator 14, 16.5 1 and ALL the Coil tec's don't match the machine. Older Explorer model owners that have the 1 and 2 swear by the WOT, so I am wondering if something was changed on the SE that would effect how well these coils work, or more importantly, don't produce. They air test fine but the larger coils (14 inches and up) don't get any more depth than their smaller counterparts like the Sun Ray 12 or the 10x14 Excelerator, both of which give me more depth than the 14,16,18 Excelerators and the 15 inch Wot. And the Coil Tecs have lousy separation on my SE's (the sole purpose of the elliptical) than coils much larger in diameter made by other manufacturers. They also false constantly and don't ID properly. There are several people using the 5x10 Joey on their older model Explorers with fantastic results. I have two different Explorer SE's, so I know there is no way that both machines are screwed up and given the same results. Please help. Is anyone getting any decent results with their SE and these coils I mentioned (Coil Tec Joey, Platypus and WOT and the Excelerators 14,16.5, and 1 ??? I am really only asking the SE owners as I already know they work fine for the older model Explorer owners. Thanks.

Hi Digitrich, I feel the same as you do about the 15" Coiltek Wot,
I like my Sunray X12 much better than the Wot for beaches.

I also have a Joey, and my Joey is AOK in my opinion on my SE !

The last is my 5" Sunray X5 which is an awesome/deep little coil, ~ it's fantastic.

While you're there, have you had any experience with the Excelerator 8" Concentric coil ?

In an old Fisher manual I once read that the 8" coil processes about 1 Gal of soil at any given time. To move up to a 12" coil, the same machine now has to process 7 Gal. of soil. I a mineralized area thats a lot to sift through for a slow machine like the SE that has been tweaked to the max in trying to out do the XSII.

Try lowering the sensitivity so the coil doesn't have to work so hard with the tracking. This has helped with the older Exploders.

Snowy,Yeah I have the 8 inch detech concentric which I really liked until the screws fell out of the five pin and got lost and then it shorted. I did get some new little screws and put it back together but I have never fully trusted it since. It was once one of my favorite coils next to the Sun Ray 8 DD. I have no problems with any of the Sun Rays, the 5,8 or 12. No problems with the Excels 4.5x7, 6, or 10x14 (sweet coil). I understand about turning down the sensitivity and gain on the larger ones such as the WOT and Excelerators 14, 16.5 &18 because they are scanning so much mineralization at once and interference and all that, so I don't really mind that there are not a whole lot of places that you can use them and get better results than a smaller coil. On the larger coils, it is almost like the SE is too sensitive for them and by the time you crank everything down enough to use them, you are better off to use a smaller coil with everything cranked up because you get the same if not better depth sometimes and better separation. Disappointing, but I understand. My real beef is my smaller CoilTecs, the Joey 5x10 and the Platypus 8.5x11 as I really need these coils to work well and they don't. I sent Coil Tec back the Joey because it wasn't IDing properly and they sent me a new one that acts the same way. MY Platypus has the exact same ID problem, just not as severe. I have tried them on both my SE's in manual sensitivity and auto, with lowering the gain and still the same deal. I sent the Joey in the first week of January, they lost it, found it and they said it was fine, lost it again and sent me a new one just last week after three months. So I am a little leary sending them in again because it was a real pain. I am very glad to hear your Joey is working well on your SE Snowy. That gives me hope. My Joey doesn't ID the same the full length of the coil, so unless I swing perfectly centered over a target I may mistakenly think it's iron and therefore ignore it, my Sun Ray's and Excelerators all ID accurately along their full length. Thanks for your reply Snowy, do me a favor and make sure your Joey ID's accurately it's full length and let me know, cause I'll send mine back in again if that is the case.

Yeah it's like there is this equation to it. On the larger coils, it is almost like the SE is too sensitive for them and by the time you crank everything down enough to use them, you are better off to use a smaller coil with everything cranked up because you get the same if not better depth and better separation. Dissapointing, but I understand. So I just save them for areas that they will work in. Thanks for your reply.

Hey JW, your 10 x 14 and 4.5x7 Ellipticals are the bomb, so when are you guys going to make a 5x10 and an 8 x11 because apparently you've got the tuning right on the money when it comes to the ellipticals and my SE's. I really need something in between the 10/14 and 4.5/7 I can count on. The separation on the 10 x 14 is an engineering feat for that coil's size, in fact, better separation in trash than many smaller coils and yet it still gets the depth for it's size. How did you get it so sensitive to so small objects, aren't large coils supposed to be less sensitive to smaller objects? Point is, you guys are on to something and I wouldn't mind having an entire brood of different sized ellipticals for specific tasks made by Excelerator. I am still PO'd at you for not replacing my 8 inch Detech concentric that the 5 pin fell apart on 4 months after I got it, and yes I waited to long to send it in but I did call about it when it was only 6 months old and received a repair number. Last year I purchased over $5,000 worth of stuff from you guys, so you think maybe you could revisit that issue??

Digitrich, I just did a test with my Joey, and got a solid set of ID numbers ( Ferr 00 Cond 28 ) ~ all along the coil...

See pic below.

# We can't get those 8" Excelerator coils down under here in Oz !
I'll have to get me one !!!

 

[digitrich]

Could I have dinked up something, the same thing on two different detectors? Can you tell me your settings you were in? Fast, deep or off, manual sensitivity or semi-auto and what # sensitivity and gain? Thanks.

 

[SNOWY]

Here's what my settings were for the test on the Joey Digitrich.

Sensitivity Value 1 ~ I wanted a steady machine, as I did the test indoors...

Audio Volume Maximum Limit 10
Audio Volume Gain 7

All the best ...

Hello,
I'm late for the party but will offer my opinion anyway.

I own several Excelerator coils made for the SE. My collection includes the 4.5x7, 12,14, 10x14, 16.5. & 18 inch.
I really like each and every one; finding them to perform really well. My favorite is the 10x14.

I recently purchased Coiltek's Platypus 8.5x11 coil. Although I really like the way its looks I find personally the coil offers no more depth and possibly less than the slimline 10.5 standard coil.
For some reason, pinpointing is a little easier however and the coil, to me at least appears to be a little more stable in noisy areas.
I do like how the Platypus coil performs in trashey areas also.

Very gracious of you sir.

Hi Digitrich,
I vary my SE settings according to what type of hunting I have to do of course...

Below is the setup I used at an old inland country swimming/camping/fishing hole...

I really like to hunt if possible with a fully zero disc level ( clear screen ) and make my choices on whether to dig or not
from where the target hits on the SE screen.

Iron mask level 22 was set because I had previously hunted an old derelict house site before going to the river.

I figured the Iron mask level would be ok, as I was after highly conductive, old silver, and copper coins.

Sensitivity Mode Manual
Sensitivity Value 20
Threshold Volume 8
Discrimination Function IM
Iron Mask Value 22
Noise Channel* 11
Display Type Smart

Audio Volume Maximum Limit 10

Take care, enjoy your Spring !!!
