Equinox 15" Coil Id's

Recommended Posts

I have been hunting with my 15" coil for the past 3 weeks or so, and I have seen a shift in the ID's compared to the stock 11 and the 6".  For example, my first hunt I noticed that the two 1911 Wheats I dug, both were ID'ing in the upper 20's.  (27 - 30).  In between the two wheats, I got a solid high tone that was id'ing in the mid 30's (32 - 37) which ended up being a 40's rosie.  In my subsequent hunts, I have found that the nickel range is pretty solid (12-13) and zinc pennies usually don't come in above 20... so pretty similar to the other coils... but higher conductors... copper pennies and above, all seem to be coming in more bouncy and with several points higher on the id scale.  Yesterday I dug a clad quarter at about 3 inches... solid 35.  I don't mind... I am digging anything in the nickel range and above a 17 without question anyway... but was just wondering if other 15" users have see the same results. 

By the way, my standard setup is Park 1, 50 Tone, Recovery 5 or 6, IB 0 on the new firmware.  I have disconnected the coil and re-installed it, run a factory reset on the machine, and even reloaded the update to see if any would change the results.  No change. 

Having said all that... I am really enjoying the performance of the 15 in my ground.  Definitely a good addition to my arsenal for those wide open parks and sports fields!

My 15 is pretty accurate as a rule on Aussie & old English coins but I am no expert on US coins.

Only if the coins have begun to breakdown does the TID differ for me

Once the coins surface breaks and its minerals within mix with the soils minerals a reaction occurs which changes the makeup of the coin a bit....this will skew TID numbers on every detector that I have owned.

Either way the target still sounds like a keeper ie the tone still screams dig me.

happy hunting 😊

I have not noticed any difference between any of the three coils for ID. Pennies can be a bit wild at times with all three coils.  Especially the copper memorials from the 60s to early 80s.  They will ring up in the high 20s sometimes making you think you might be on to a silver dime.. kind of kick I the gut.

Most likely operator error giving me these erratic results.  ;)

Thanks for the responses everyone. 

I had a hunt yesterday that I felt like I was holding onto both reigns trying to control the 15"... constant barrage of tones all over the scale.. I don't blame the 15"... I blame myself for not matching the coil with the site.  I will continue my education of the Equinox and the 15" coil... as they say... time takes time.  :)

I don’t think it’s operator error Tim.  The Equinox is very good at keeping a target in its conductive range to full depth in my ground but it does not always have the very tight ID numbers that the CTX or even E-Trac has.  I’m ok with that because as an old coin hunter I’m digging anything 18 and up anyway.. Just makes for an occasional surprise.

My concern is what happens when you go to even larger coins (halves or large format dollars).  Does it wrap around to iron zone?

Try one and see what happens. My testing with the big coil puts the big silver coins in the 38-39 area and stacked silver rounds at 40.

I would of thought the Aussie $1 would now read more often at 22 VDI and the $2 at 21 with the $1 being the bigger coin.

With our $1 being smaller than the $2 the $2 now reads most often at 22 on the VDI with the $1 favoring 21.  This is only with the 12x15 coil, on the 11" and 6" they both favor mostly 21 for me bouncing to 22 a bit.

My 15” coil arrives tomorrow so I was searching forums for tips/problems before I start using it.  When I read your recent post, I thought I’d share what I’ve learned.

The jumpy VDI might be reduced if you back off on the recovery speed (RS).  I found this when using the 11” coil, when I can, I back off the RS when swinging over a jumpy high tone and it does calm down.  Try ithis with a variety of high-tone targets and see if it helps.  

From what I’ve read, most guys swinging in test gardens find that it is necessary to use a RS of 4-5 with the 15”.

      I have recently been using my Equinox 800 for saltwater hunting.  The obvious settings, Beach 2,  Iron off.  Since I am forced to a slower swing, I drop recovery speed to about 2-3 (4-5 on beach).   
      I am forced to drop the sensitivity to 15 or below.   I have noticed the waves will cause signals and dips in the sand too.   This has become frustrating as I use a CTX-3030 and do not get nearly the false signals.   Any suggestions to try?

      Hi Folks
      I have been busy making quite a few finds recently. After more than a year with the Equinox, it continues to impress me with it's capabilities.
      Some of my recent finds include some early 1630's Kettle Points and Turtle Effigy, Spanish Silver, KG's and more. I even have had it scuba diving. Unfortunately I wasn't impressed with the volume with the Grey Ghost headphones. I have a new pair of Tony Eisenhower headphones ready to try out with the hopes that the volume is better. We shall see.
      HH Everyone...

      In a previous post of mine, I made the case for using 3 tones based on Low, Medium and High conductive targets; a system I routinely use in hunting our Florida beaches.  It's simple, effective and gives me the information I really need.
      The videos below however, make a strong case for 2 tones and the "Dig it All" approach when using the Equinox series detectors.   Why?  As you'll see in those videos, the tested targets span the VDI spectrum based on metallurgical composition, shape and size. Granted, these are nothing more than air tests which aren't affected by depth, moisture or ground mineralization but they at least provide some indication as to how a variety of targets range the VDI scale based on their individual characteristics.
      If using 2 tones, I would personally set the tone breaks at -9 to 0 using tone pitch 1 indicating probable junk and the second tone break at 1 thru 40 using tone pitch 25.
      If I were interested only in a more detailed target description, I would lean heavily toward the CTX 3030.  However, in the type of beach hunting I do, I favor the Multi IQ, faster processor, enhanced sensitivity and weight of the EQX over the CTX...just my personal preference or as I always say, "Just the view from my foxhole."

      Need help. My equinox 600 doesn't change discrimination patterns when I switch detect modes. I am always in all metal mode. My boyfriend has the same machine and his changes with each mode...he doesn't know why mine does not. I can't figure it out...help please.

      I was having a relatively slow morning detecting at La Jolla Shores Beach in San Diego today, about $1 in clad and a euro coin when a young woman came up asking for help finding a ring. She was frantic and her husband was second guessing, saying it must be at home and asking when was the last time she saw it? She kept insisting it was here right here, next to the seawall. With just a couple swipes of my Equinox 800/15" coil I had it in the scoop. She was ecstatic and gave me a big hug. I've always dreamt of finding a big expensive engagement ring whilst detecting. I've gotten a few gold bands but nothing like this! I obviously didn't get to keep it, but it seemed to bring some good karma to the day and I found two large silver rings shortly afterward. She insisted on getting my info and address so I might be getting a reward or thank you letter later. Here's a couple pics of the expensive ring, the happy owner and the two silvers I got afterward.
