sef coils on excal

[eloros]

hi many thanks to all for there help on my last post . i was wondering if possible to fix sef coils to my Excalibur thanks

 

[Critterhunter]

Yea, but I wouldn't use the 15x12. Too much drag for my taste in the water. The stock 10", 12x10, or S-12 are all good choices.

 

[grumpyolman]

Critterhunter is sharp on electronics but...does the difference between a Broad Band Spectrum vs. a Full Band Spectrum coil make a difference? Thought I read somewhere that some of the FBS coils that work on the E-Trac/Explorer weren't compatible with the Excal. jim

 

[erikk]

I kind of like the WOT myself

 

[hershey1]

I'm with you Grumpy I don't think SEF coils are compatable with Excals.

 

[goodmore]

I actually think the people at Minelab got this one right. With the choice of the 8 or 10 inch coil. Drag in the water plus the ability to pinpoint. And now since my last beach hunt the EMI factor. The stock 10 inch is hard to beat. IMHO.

 

[kered]

SEF coils are made for both BBS and FBS, not interchangable (as well as VLF, even the ace250 and tesoros)any coil for the Sovereign should work on the excal, I had the 15x12 on the sov Elite but sold it with the machine, i now have the 12x10 and wot15 for now on the GTand XS(till i get another 15x12) i would like to see a BBS version of the minelab 11" pro coil that comes on the etrac and SEpro its much thinner than the Excal 10" and i suspect good for the water re drag etc or lack of it, it very light too, and if they would only make the SEF BBS 8x6........

 

[Critterhunter]

Kered, want to trade that 12x10 for my 15x12? How do you like the 12x10 in comparison to it depth wise?

Any Sovereign (BBS) coil will work on an Excal so long as you can wire it up. FBS (Explorer/Etrac) coils don't work on the Sovereign or Excal.

 

[kered]

if i was in US i would do it in a moment, i hardly use it as i prefer the Wot 15, no idea what the postage would be but i can find out, probably the same for you to here, definately interested though

 

[Critterhunter]

I forgot you are in another country. I think I've got a trade in the works anyway. Somebody with a 12x10 with a bad coil connector wants to trade it plus $50 for my 15x12. I love the 15x12 and while it's not as deep on land for me as the stock coil, it is deeper than the stock Tornado on the beach. Still, on land I am looking for something deeper than my stock 10" Tornado. Not that that coil isn't real deep already. I've dug deeper coins with it than I have on any other machine. It's just that I'm always looking for the edge at my pounded out sites in any way possible. I also prefer a little more coverage than the stock 10" coil provides. The 15x12 is great in that respect but best depth is my ultimate goal for land hunts. If the 12x10 or perhaps S-12 gives me just a little more depth than the stock coil on land then that's what I'm shooting for. I'll probably end up with the 12x10 because I bet the depth is about the same compared to the S-12, but I'm pretty sure the 12x10 will separate better based on that awesome ability on the 15x12.

 

[kered]

Ok i understand, me being 99% beachbum the 15x12 suits me fine, the 12x10 should be ok as i'm not getting much difference between it and the Wot 15" but the wot gives slightly better coverage and maybe a tad more depth on the bigger coins, the sef seams better at depth on the smaller items(more sensative) although i've never run them together on the same target to compare in a controled test.

It would be interesting to try the WOT against the 18-15 SEF just to see what the difference would be what is the difference between the Excelerator and the SEF coil?

 

[Critterhunter]

Excelerators are usually referring to the "old" round Detech coils that KellyCo still sells. They come in like 12.5, 14, 16, and 18" sizes. The 12.5" is said to be about the same as the S-12 in performance I think. I think the SEFs (?) are made by the same company (Detech). The 15x12 is a more close comparison to the WOT as I think (?) the WOT is 14.25" in diameter. If you dig up an old thread in here about Coil Opinions & Stats I've got a chart with all the coil sizes and weights. WOT is the heaviest. There is also a picture of the WOT laying under the 15x12 as well as the 15x12 over the stock 10" coil. Most say the 15x12 is a better coil than the WOT in terms of pinpointing, stability, separation, sensitivity to small targets, and is at least as deep or even deeper than the WOT.

The 12x10 is said to go deeper than the stock Explorer 10" or 11" Pro Coil as well as the Sovereign's 10" coil. It's also more stable than any of those and will hit coins on edge or unmask them better than those stock coils. In a field test of the 12x10 and 15x12 the 15x12 gets slightly deeper on dime and larger sized coins, while the 12x10 is a half inch deeper on something as small as a half dime or even smaller (cut quarter penny). As I've said I believe the 15x12 might not get more depth than the stock coils or the 12x10 in high mineral sites due to the target getting lost in the ground matrix. It will run stable at higher sensitivity settings than stock coils but in high minerals I don't think that gets you best depth anyway. Something much lower IMO does, so stability at higher sensitivity levels would probably only be a bonus when the soil minerals are low enough to benefit from maxing out sensitivity. I can say the 15x12 runs in rough ground or iron much smoother than the stock 10" coil and it is deeper for me on the beach, but on land I feel the 10" coil is deeper in my high minerals.

One other thing on the Excelerator coils (the round DD coils)...There are I think old and new versions of these coils. The old ones did not perform as well as the new ones. I think the originals were called Penetrators which the new ones might be as well but I also think the new ones (?) are called EQ2 coils or something like that. Somebody might correct me on all this. For that reason if you are in the market for a round Excelerator you might want to make sure it's the new version of it.

I'd like to see some comparisons of the round 14" round Excelerator to the WOT as they are pretty much matched in size I think and are both "standard" DD designs.

I seem to remember seeing a chart on the various coils .....and from personal knowlege the WOT coil is heavier than the SEF 12 x 15.....The coil cover is also additional weight and cost .....The 12 x 15 SEF also seperates better ...... BOTH coils are said to go deeper than the round Excellorators ....At least this is what I remember wben seeing the KellyCo chart .....I don't know where that chart is now .....Maybe I saw it from Critter .???????....Not sure ....... With all the features of the SEF coils , including they read coins on edge better than any other coil out there , I would tend to go with them .....Now if they could only make an 8 x 6 SEF for the Sovereign .... I wouldn't be surprised if the 10 x 12 SEF coil were lighter in weight than the stock Pro Coil on the E Trac , and that's a pretty light weight coil !!..... Jim

I found that the 12x10 is deeper than the 10" on the etrac but on par with the 11" pro coil to a point i kept the 11" and swapped it out for the 18x12 as the 11" is much better in the iron and also lighter, if any difference in depth its negligible, only problem with the 11" is it can be too sensative for small items for me, like minute bits of aluminium, presstuds, earing backs and the like, i have dug some deep holes only to find something like mentioned.

Not tried the Wot on the explorer but on the Sov the 15x12 was better for me on the beach, in all aspects(the 11" pro coil is a very great allrounder, pity its not made for the sovereign)

On the etrac the 18x15 is heavy if targets are few and far between especially without a bungee, if getting targets regularly its not too bad, i'm finding in some places i have to run it at lower sens than the 15x12 so any depth gain from bigger coil is nuetralised by the lower sensitivity, other places i can let it rip and it does well.
The main thing i like is the coverage for fast clad hunting to clean up before the beach cleaners,(minimum sense) its hard to keep up with especially on the dry.
Not had it long so the jury is still out, maybe i'll hang onto it for the winter to see how it copes when targets get thinner and deeper

 

[Critterhunter]

Kered, surprised you feel that way about the 12x10 compared to the 11" Pro Coil. Most people I've read talking about them like the 12x10. Deeper, gets coins on edge better, and less false hits than the Pro Coil.

 

[wildherre]

I don t care for the 10x12 much either.. Little or no more depth than the Pro. Also tried a 12x15 0n my Explorer & Etrac , no additional targets recovered on previously hunted areas ,, Also had a 10x12 for my Sovereign GT.. Saw no improvement over my 10 incher Maybe a little quieter.. .. The best coil I own for the Sovereign is my sea search..I have recovered coins at great depths with it.. It was my secret weapon against my first Explorer ... The best coil I own for the FBS machines is my SEF 6X8.. I always leave home with the 10x12 on & always come home with the 6x8 on.. The larger coils are good on angle coins, Ive got a WOT I use on the Sovereigns for that.. Id also would like to see a 6x8 SEF or the Sovereigns... This is for inland park & old school type areas... wildherre

From my experience lots of those false hits are not always false hits they are minute pieces of something as its so sensative, i'm talking half earing backings and smaller, last night i picked up a winder from a watch, no idea of the depth as the scale on the meter is relative to size and it came out on the first shovel full but was a bu**er to find in the dark(the pocket uniprobe saved the day but took some time and had to almost touch it to sound off)

 

[synthnut]

The Pro Coil on the E Trac is no sloutch .....It's a nice coil and is very light weight .... You really can't beat it for an all around coil .....There are better coils for a specialized coil, but for an all rounder , the Pro Coil is not a bad coil .....Just like the 10" Tornado is a pretty darn good all rounder on the Sovereign ....Again , there are better "specialized " coils for "specialized " purposes , but for an All rounder , the Tornado is not bad .... Tell me more about the Sea Search coil ....That sounds like an interesting coil ......The 12 x 10 is too close in size to the Pro Coil for me to get one for my E Trac and it's pretty close in size also to the 10" Tornado for the Sovereign , so I kinda ruled that coil out for either machine ....Same goes for the Sunray S-12 ....If I'm gonna pay a couple hundred bucks for a coil, it's really going to have to do considerably better than what I have for it's intended purpose .... Really good smaller coils are GREAT for playgrounds and parks , etc ........ They seperate better, they can get into smaller spaces better, and you can raise the Sensitiviy up high enough that you can get pretty deep with them .....Add that to the abiltiy of the SEF coils to read coins on edge better, and you have a great setup in the 6x8 SEF that will do better in some cases better than the stock Pro Coil ... Going to the beach , the 12 x 15 SEF just plain WORKS !!....It covers ground, and for the life of me , I don't know how they got it run more quiet than the Pro Coil but it does .... I put a Swingy Thingy on and can beach hunt all day with it .... Sooner or later, we're going to have to accept the fact that perhaps we have met the limit on some of our coils and machines .... that is until the next latest and greatest setup come along !!....

I have WOT's on 2 excals. I love them... I do not want to dig any deeper, I get signals very deep on minute targets and in the water I do not have to worry about coins on edge or target separation and IMHO the difference is about $500.00
