6" Coil On The Way!

Recommended Posts

Hi all!  

FINALLY, after a long wait, I have a 6" coil on the way.  I'm really looking forward to trying this coil in some really trashy spots I have in mind.

A question for anyone that has the coil -- have you done any depth comparisons with it and the 11"?  I'm curious as to how much depth would be lost, given equal settings, on a coin-sized target?

Thanks!

Steve..... one or the other of those coils will suffer if the same settings are used.   The larger coil in a trashy area takes is a LOT more material to process....... depth isnt everything and often times you can benefit from not running a hot coil.    Its better to run both coils optimized for the area and target and let the results be your finds.

Dew --

True, you are right of course.  I guess I shouldn't have said "the same settings."  Given that you are processing less "stuff" with a 6" coil vs. an 11", you can often run sensitivity higher on the 6", in my experience.

What I was trying to figure out is that I have a couple of places back in PA which are littered with square nails; one in particular is an old church that dates to 1800, but has burned at least twice -- so the remnants of those burns (square nails, etc.) are everywhere.  I have made some good finds there; I got in there for a short while about a month ago while back home, for the first time with the Equinox, and surprisingly managed to pull another 8 Indians; that's more keepers than I ever pulled from this site in one hunt, and I've been hunting it for years!  But, the targets are deep; greater than 6" in all cases and often 8" or even a bit more.  So the gist of my question was this... obviously the 6" coil will help me to pick amongst the nails at this site, but will it have enough "umpf" to get down to those 6" to 8" targets?  It won't do me any good to be able to see around the nails (in this particular site) if I can't get enough depth to see the targets that are down there...

So that's where my mind was going when I asked the question.  I agree that depth is NOT everything, but at some sites (like this one) it IS important...

My experience with Minelab machines and DD coils is that you still get great depth even with the smaller coil. The size  and depth difference is more pronounced with concentric coils. You might lose maybe 20% depth, but you can also increase sensitivity on the smaller coils.

I agree; 6" coils on other Minelab machines (specifically FBS) got really good depth.  I'd have to assume similar results will be had with the Equinox 6"...especially with sensitivity bumped up (as a smaller coil usually allows).

Look forwards to your take on the small coil Steve ?

Look forward to your commentary on the coil Steve.

I think it’s a modern trash PERFORMER !!!

Steve ....... the advantage of having more than one coil is that you can hit the area with the larger coil..... then go back over it with the smaller.   Not sure about the 6" loosing 20% depth...... maybe in an open field but trashy area can give various results on targets and depth.   THEN it depends on the trash....... small high conductors might give you a fit with the small coil.   Coils are just another way to tune your detector.

I would love to see someone post a base line for air test distances with the 6 inch coil vs the 11 inch coil, with the same program and sensitivity settings....just to get an idea of what to expect from it.  I realize things in ground will be different, but I like looking at data like that.

 

Don't look like I will be able to get one of these any time soon so data from those that have them is all I have to occupy me.  There's one on ebay now for a Buy it Now of $450.  I think I will pass.  lol

I got the coil in the mail yesterday.  Perhaps I will make some time to do just the testing you mentioned.  I am curious as well.  Indeed, as you said, things in the ground are different, but it should be interesting to see the results, anyway.

As an aside, this seems like a good place to share a somewhat interesting thing that happened on a hunt the other day.  I was hunting with my Equinox, sensitivity 24 (almost no EMI present), and the 11" coil.  My friend was hunting his E-Trac, with a 6" Detech Excelerator coil, and he was hunting in auto sensitivity (with lots of iron in the ground in places, he was trying to combat all the threshold nulling).  Now, with him running "mild" settings (i.e. auto sensitivity), and me running hot at 24, this is not a good comparison.  However, we were comparing signals during the hunt, as we usually do.  At one point, I came across a solid, but deep signal -- classic deep-coin hit with the Equinox, but I couldn't get it to lock onto a good, small range of ID numbers (as is often the case on the real deep ones, for me).  I was thinking wheat cent, with most of the IDs bouncing around mid 20s, but wanted to see what kind of numbers my buddy would get on his FBS machine, to see if his unit suggested "wheat cent" as well.  I marked the top-dead-center of the target, and had him swing it with his E-Trac, and he got NOT A PEEP.  Not even a break in his threshold.  So, he went to auto +3.  Still no joy.  Finally he switched to manual, and cranked it up, and then he was able to pick up the target (though with skewed ID numbers, especially his FE number, to the point where he said he may or may not have dug it.) 

We repeated this same thing on another deep coin a bit later on -- identical scenario in that the EQ picked it up well, but some bounciness in the numbers, while a cross-check with his E-Trac with 6" coil and auto sensitivity was a no-go.  Not entirely surprising that this happened, it was just interesting to see how drastically the use of different coils and different settings will affect results.

Again, I'm just putting this here for the sake of information; it's only peripherally related to what we are talking about -- in that we did not have our machines set up similarly at all.  The two interesting things I took from this were that ONE -- with a small coil and auto sensitivity, his machine was entirely blind to a coin at about 8" deep that the Equinox with 11" coil and running hot presented a clear "dig me" response on, and TWO -- switched to manual sensitivity, cranked up high, the E-Trac and small coil was able to give a reasonably similar response to the target that the Equinox running hot with larger coil did.  

Just wanted to share; nothing ground-breaking, but worth mentioning I thought.

Meanwhile, I will try to make time for some air testing with the 6" vs. 11" EQ coils...

Dew -- I agree, on your point about working a site with the 11", followed by the 6".  That is how I approach real old, relatively small sites, where I want to try and extract every good target that I can.  It's also how I will approach the particularly "trashy" sections of parks and yards that I've hunted hard with the 11" coil in the past.  It's time to "re-hit" some of these spots with the small coil...

      Just throwing this out in case anyone else has had this problem or for future reference.in case anyone has it in the future.  I bought my Equinox 800 in April 2018 and it has been great with no problems until  a month ago. I started getting problems ground balancing and getting very different ground balancing numbers even over the same ground.  I tried factory reset but didn't help .  Also, it didn't always have the problem. I called Minelab and they had me send control pod and 11" coil to their service center in PA. in early June as it was under warranty.  (thankfully). After getting message they had it and processing might be delayed due to Colvid-19 issues I finally heard back from them July 7.  They indicated "after much testing the unit has begun showing issues.  However, the issue is very sporadic and does it when it decides too.  The issue is a ground balance issue. When trying to ground balance the unit it will ground balance correctly.  The unit will be wildly off in the 80's.  Next it will ground bale to 0, all in the same location of a couple of feet. The difficulty of pin pointing it however is that it seems to do it even when replacing an item.  Our test coil will experience the same issue on the customer's pod.  The I tried the customer's coil on our control pod and will experience the issue again.  I have done factory resets and reloaded the latest firmware to insure it was not just a software problem. Out of an abundance of caution, I strongly recommend the replacement of both the coil and the control pod.   NOTE: There will be a delay on the control pod as there are parts difficulties due to Covid-19. Once art is received  we will update the ticket and return the unit to the customer."  This all was very weird.  I recontacted Minelab about what the new timeframe might be for getting my detector back and why I just couldn't have them send me a brand new detector(minus wireless headphones] .  No response back as yet.

      Found a 1926-D Mercury dime and a 1908 Barber dime today. Just about passed out from heat stroke in the process, but I got 'em.

      They were about eight feet apart and both about four inches under the surface. The Merc is in pretty good shape. It rang up 25-26 on the Equinox.  The Barber is more worn and has a gouge in the rim on the lower right in the pic.  That one rang a little higher at 26-27.

      Also found a very green 1936 Wheatie about a foot from the Barber dime.

      In my now bone  dry ground I buried this target at  about 3inches,maybe a tad more.With the earring  lying flat on the ground and the post facing me I might get a weak signal one way but it is so  soft and not   repeatable that it would be hard to hunt this way with the GMX and 4by6 coil.It is hard also to  tell it from a false  signal.This coil with the cover on is a fail for me in this test.The earring is 10k at 2.8 grains.

      Hey guys,
      I've been using my Nox 800 underwater (salt water) for some days now (7 underwater hunts total, about 2 hours each), and thought I could share some first results, plus give a nice and cheap alternative to the minelab yellow headphones for underwater use if anyone interested.
      My first ever snorkel-dive with Nox in my usual pebble beach was by using just the speaker (no headphones) with my head submerged, and as expected, I soon realized that this wasn't enough...even with my head underwater was very difficult to hear through the speaker due to extremely low volume even in calm sea...(however, as already posted in my first topic in the forum, I was still able to get my first whote gold ring with Nox using just the speaker 🙂). Anyway, in my second hunt I bought the Minelab's yellows, but to my experience with them, again I wasn't able to hear the signals good enough underwater due to their low vol especially after some minutes underwater when the soft earpads and the space between was geting full of water. Furthermore, the yellows are huge headphones and I need to be more descret in my beaches this time of year. In my last hunts however, I tried something different and wanted to share my experience...I bought a pair of 100% waterproof and submersible swimming in-ear headphones especially designed for swimming and watersports that had some quite good reviews from athletes around... the product is the "H2O Surge+ waterpoof headphones" (company is "H2O") and bought them for $40 through Amazon...(arrived from amazon UK). Well guys, in my last underwater hunts with them, my experience is tremendously good....their sound quality underwater and their volume is honestly out of this world, and I'm not kidding...especially when comparing to Minelab's yellows. Volume is high enough to hear even the tinniest faint signal and you feel the tone inside your ear like hell... their earplugs completelly seal the external sounds also, and their sound-tones & bass quality is very immpresive for such a small pair of headphones. These small earbuds come with a 3.6ft straight cord so at least for me were comfortable enough while snorkelling and still able to leave the Nox in the bottom (chest depth max) while relaxing in the surface with my mask waiting for the "recovery fog" to leave. Their speakers are 100% waterpoof (IPX8 rating) and can be submerged to 3.5m depth no prob. The company states that maybe sometimes they need equalization (blowing air inside them) but sinnce now I didn't need it. However the cord is thin so you mast be carefull not to stretch it, and if you feel to you can make an easy mod to seal the hole-plug of the Nox where they are inserted (I made a simple yet effective mod by drilling a small hall to the original plastic protective threaded plug of the nox, and used 2 perfect fit o-rings inside to seal the 3.5mm jack connection while screwing the plastic plug...you already know that the nox is waterproof in that point also, but better safe than sorry and made the extra mile to seal it better). As already stated, the H2O earbuds are designed for athletes (especially designed for swimming and watersports) and come 5 sets of earplugs to fit perfectly in every ear...in my ears they fit so nice and they completely seal external sounds and water from my ear canal. Don't wanna say much more about them, and waiting to see how they handle overtime, but as for now I'm totally impressed with them and their volume and sound quality, and my finds went immediatelly up.
      Furthermore, In fear of flooding the Nox in the future as many other members experienced, and in order to make it more usable underwater while snorkelling, I made some extra mods. I totally water-sealed the machine by: a) using silicon paste inside the battery compartment inside the handle (removable if needed but should be a pain to remove)...b) used marine epoxy paste to seal the control box and screen perimeter where the plastic parts join together, and also sealed the point that the control pad meets the handle (critical point there).... c) completelly sealed and eliminated the external speaker (will never use it anyway)...d) made a custom shaft by modifying the original lower shaft to shorten it and also drilled a small drain hole near the bottom...I know I may void the warranty with my mods, but took the risk and now I'm using the machine underwater with piece of mind.
      Results: As already said, I have used my Nox underwater for 7 hunts till now...about 2 hours each. Attached some photos of the finds. In these +/- 14 hours I have:
      - 4 gold rings: All are solid gold (14k & 9k the smallest one), except the large and heavy one wich is bi-metal silver with 14k gold piece on top. (ps. the top white 14k gold ring with small diamonds is the one I posted some days ago)
      - 1 crusifix (silver with gold Christ) 
      - Almost €22 in change
      - 82(!) old clad coins (all are pre-euro drachmas..no worth unfortunatelly, but yeap 82 of them in these 14 hours)
      - Good amount of lead sinkers (including some huge ones)
      - 2 spoons, 3 keys, a jank pin jewel piece, a junk watch, and a live HXP-95 military cartridge (strange to find it underwater though..!)
      - Aluminum junk: MINIMUM!..we're talking almost no junk comparing to dry hunt!!! I think I gonna love this underwater thing!!!!! 😄
       
      Ps. My Nox settings if someone's interested are: Beach 2, Recovery @5, Iron Bias F2@0 , 2 tones only (pitch 1 for iron / pitch 23 for non-fe), notch only -9 to -7 to avoid ground/ceramic rocks underwater (all other is open and able to hear iron from -6 to 0 in low vol pitch 1), tone break @0, sensitivity @17, GB manual by pumping sideways (have uneven bottom), no threshold.
       
      That's all 🙂
      Happy hunting everyone!
      Argyris

      its just an old brass shotgun shell , but if you knew how hammered this spot is you would be impressed to . Took the 600 and small coil out to iron hill and nver exepted it to pull another target out of this pounded spot but it did, i was using the 6" coil and had it in park 1 sweep speed 3, and 0 iron bias , all metal and you get low and high tones of the ends of the cut nails but only in one derection. wel in the mist of this mayhem i got a mid tone but was weak in one derection but becuase it seems more solid i dug it and from 6" down comes a very old brass shot shell . wich blew me away because ive hit this spot so hard its a grassy ovel about 30ft long and 25 ft wide just amazed

      HI Guys!
      I know it's comparison apples with oranges but was curious about depth in mild ground between these two machines.I know in mineralized ground ATX is deeper than Equinox,thats for sure.I'm going to hunt a lake with no mineralized ground and in this condition I will know which detector is deeper.Any tips???
