Recovery Speed Comparision

Recommended Posts

There is a thread on "other sites' asking about recovery speed and depth? With SALT WATER. The only question was do you loose depth, in a higher recovery?  I would say with the NOX at 6 there is a balance with quiet running and depth in salt water.[esp with black sand]  With a machine like the Sovereign in all metal Pinpoint mode it is doubtful you can overswing or swing this too fast on ANY salt beach. Yesterdays take with the sovereign in all metal pinpoint [for those who never had a 186 coin day]. [347 pesos]

Recovery speed is primarily a way of getting good target separation in dense trash.

The faster available recovery speed is perhaps the biggest performance advantage of the Equinox over other Minelab detectors.

I received conditional permission to MD on a site that has interested me for years because of first-hand stories I have heard. It is my first such site and I have spent about 15 hours of headphone time there, spread over 3 hunting sessions. Many nails, lots of other “trashy” stuff. Interspersed among these were some modern coins and a copper? relic (not pictured) found on my first outing, and other non-ferrous items. I am using Park 1 and have kept pretty close to the default settings but yesterday I ventured into Recovery speed - just so happens the topic of this thread.

It seems to my ear that at a recovery of 6 (default) and moderate swing rate the Nox will respond to targets fast enough that the rapid distinct bursts of audio are difficult to separate, isolate and locate. When a desirable tone is heard I retrace and slow my swing in an attempt to lock its location. Yesterday, during my last hour or so, I intentionally sacrificed any notion of depth and experimented bumping the recovery between 6-8 and slowing my swing. I also reduced sensitivity to 15. Even with the settings changes, I was digging miscellaneous non-ferrous bits up to 4-6 inches - no obvious loss of depth compared with prior time spent on site.

I include a couple of pictures from yesterday to better display the site I thinly described (and shorten this post by 2000 words). How would others suggest I best apply the Recovery setting to swing speed? Site specifics aside, does a higher recovery speed necessitate a slower swing rate to advantage or does it allow for a faster swing to cover more ground? Or both? Or other?

186 to 1 ... your favor. Do my aluminum bar stock, and silver (plated) unicorn, and a beercan-sized hunk of lead count? ?

It’s all about how the machine is reacting.

That is precisely what I experienced. If I slowed recovery I found I was missing tones that were more distinctly audible over the same targets in faster recovery. The density and the machine forced me to increase recovery and to slow my swing way down in order to take advantage of this Equinox power talk. Trying to anyway. The layers of targets - ferrous over or next to non-ferrous -produced tones that made this an enjoyable challenge, especially when I would finally isolate a tone I believed would be worth digging. At that point, I could use the meter. However, until I could isolate a good tone the meter was confusing and seemed out of synch with the tones that were within my ability to distinguish. TID became useful when I managed to narrow the audio. Some of the smaller bits were inadvertently collected in the process of going for a non-ferrous target. The other ferrous stuff was just plain smarter than me. Keying on recovery speed coupled with some sensitivity adjustment now makes some sense to this neophyte. After a few more sessions in this iron labyrinth, I will be moving on to what I hope to be choicer permission I was kindly granted. I gotta say this: I feel fortunate to be starting on the Equinox - like walking on the shoulders of giants past and present. Quite a platform you guys have collectively assembled!

Steve do you ever find yourself going to 8? So far 7 is as high as I have really run the nox much. 

I am nearly always running recovery speed 5 or 6, with 7 occasionally and 4 rarely. I basically never use 1, 2, 3, or 8. Not saying there is anything wrong with those settings for other people and places. It’s just what works for me doing what I do. :smile:

Recovery speed allows one to swing faster but for some reason people are interpreting this to mean they should swing faster. There is absolutely nothing that says because you increase recovery speed you should increase your swing speed.

I always assumed that was the case but have never seen it written.   Good tip.   ???

Iron is smarter than everyone.  Sure, more experienced detectorists will sort out some iffy targets, but the right collection of iron will conspire to make a signal good enough to dig.  There is no shame in digging an iffy target and finding iron.  Contrast that with skipping an iffy target that turns out to be a keeper.   Only one of these gives you the true answer.  When in doubt, dig it out.

      As mentioned previously, after rereading Dick Stout's Coin Hunting... In Depth book over the holidays I took his advice and stepped away from my standard sites to find new ones.  It seems to be working (thanks, Dick).  Statistics on that later in this post.  Last week I went to one of those 'new sites', a century old park, and in the first 2 hours I found 83 cents in modern coins searching along a road and around a crushed stone parking lot that had previously produced only one old coin -- a beat up Wartime nickel ('Warnick').  I decided to move to a picnic area for the last hour, and as you can see in the picture, I was rewarded.  (Sorry for the overexposure on the Warnick.)

      One of the Buffies showed up first, about 5-6 inches.  Next was the Merc at 4-5 inches.  The other two nickels followed (neither more than about 4 inches deep) and the big surprise was the Indian Head, also only about 4 inches deep.  My previous Personal Record ('PR') was only two old coins in one day's hunting.  Note that I don't count Wheat pennies in this category.  My single day PR there is 27.  Needless to say I was quite pleased.
      Oh, the 22 cartridge was found next to the above mentioned parking lot on a previous hunt.  Given that it's in a muni park (and we don't have gang problems..., etc.) I assume this was dropped long ago.  It's possible it was dropped after the park opened by a hunter who was getting his gear together after getting out of the car, before exiting the park on foot into the nearby woods.  The lead bullet appears to have 3 rings, one smooth and two serrated (if that's the correct word).  Can anyone put an age on this?  It was oriented vertically about 6 inches deep and sounded as sweet as any silver dime I've ever found, with the TID centered around 27.  Except for the 'P' on the back of the Warnick, there is no mintmark on any of the other coins.  The IH is 1903 and the Buffie dates are only partially visible.  I think one is 1916 and the other 1924.  None of these is scarce, but they still get counted in my 'other old coin' category.
      A little about the park.  As I mentioned it was established over a century ago.  I knew of its existence but figured so did every coin hunter within 100 miles.  Surely there was nothing left for me....  But another thing I've learned is that there is no such thing as "hunted out".  I've put 52 1/2 hours into hunting this park so far (all in 2020) and there's still more uncovered area awaiting.  Here are some numbers to mull over:  my 'other old coin' finds per hour is 0.27 for this site compared to 0.08 for all other hunted sites since beginning of 2017.  8 of the 14 finds are nickels.  Meanwhile Wheat pennies recovered per hour is 0.21, compared to 0.26/hr for all other sites starting in 2017.  And here is a sampling of my trash finds:

      These are from 12 1/2 hours of hunting this park.  All but a couple of the ring-and-beavertail pulltabs had Equinox TID's in the modern USA coin regions:  12-14 (nickels) and 19 and above.  If the nickel and pseudo-nickel target ID touches 15 I don't dig.  My custom high tone is 20 and up to make sure I notice Indian Head pennies.  (Note from the photo: I count Zincolns as trash and that's what the pictured discs are.)  The 14-18 region is typically thought of as pulltabs, but those in the photo (exception of a couple r&b's) all sounded and TID'ed like nickels.  The aluminum screwcaps TID 21-23.  Crown caps can be in both nickel zone and Zincoln zone (elsewhere, too), depending upon composition.  I did dig more trash than this, mostly can slaw but also some aluminum foil and the usual few bent nails, square nails, copper wire, etc.  This park is absolutely loaded with the old pulltabs, and the broken off beavertails are the worst.  It got to where I was requiring the TID to at least flash a 13 for me to dig 'nickels', and still you see what I pull out.  Unfortunately I later dug a pure 12 and it was a nickel.  😪  I wonder how many of those I left in the ground.
      If you're still here I hope you don't mind one more statistic:  for common coins of denomination 25 cents and less (so not counting Wheaties or other old coins, but including Zincolns), the fraction of nickels among common coins since beginning of 2017 (but not counting this site) is 15%.  At this site (again, not counting the eight old nickels) is 26%.
      In summary, I'm finding a lot of old coins compared to my other sites, but not more Wheaties.  I'm finding a lot more nickels (relative to other coins) than my other sites.  I'm finding tons of pulltabs in the nickel zone.  How does all this tie together?  Simple:  the site has been hunted by detectorists cherry picking the high conductors and ignoring the nickels because they don't want to dig pulltabs.  Of course they missed some Indian Heads (probably didn't want to be bothered with Zincolns either) and a few silver dimes.  Hopefully I'll find a higher denomination silver coin, but even if I don't I'm happy with the oldies that have been showing up.

      After a bit of a drought of finding cool coins with the Equinox, I found another V nickel detecting in the neighbors parking strip in between thunderstorms.  It was pretty worn and pitted, and not of any numismatic value, so I cleaned it up a bit.

      I find myself waiting again for something new they call Apex .
       I had been thinking about buying the Vanquish 540 pro pack but about the time I was going to pull the trigger on it another toy pops up. The trouble is I can’t have it today and not even tomorrow. Just like always I find myself in line waiting on something or someone.
       Well I’m not standing in line for nothing anymore.
       I’ve had a Nox 800 but sold it and I’m still kicking my butt for doing that . I had a detector that out shined all others and like said stupid sold it.
       Enough is enough so I called Rob and ordered a Nox 800 , 6” coil with a extra lower shaft and a MI 6 XP Pinpointer for my ORX .
       I ordered this just this past Monday and by 6 the next morning the check was in the mail. 
      I wish all of you the best that’s waiting on the Apex. Just mark me off that waiting list . Chuck

      I was hunting at the beach yesterday and did my usual "dial it in" routine...adjusting F2, Recovery and Sensitivity using my test sticks to optimize my EQX 800 performance for that particular beach.

      As I hunted, I got a strong tone of a high conductor and started to dig and dig and dig. I couldn't see or find the target but I knew it was still there...somewhere...the EQX said it was!

      I finally narrowed it down to a certain pile of sand from the ever growing hole. Still couldn't see it but it was there among the brown sand...somewhere. Finally resorted to my Pro-Find 35 pinpointer. It rang up nicely but I still couldn't see this high conductor! I started to test small hand fulls at a time and finally...finally I saw a minuscule piece of wire on the edge of my hand. Could this be what all the fuss was about? YES. I measured the depth of the hole with the Pro- Find 35 and saw that it was approximately 8 inches!

      I brought the wire home specifically to post this story about the importance of adjusting your detector to meet the conditions. When we change beaches, I "dialed in" my EQX again for that new beach and had to change the settings from that first beach where my EQX sniffed out that piece of wire. Conditions change and so must your settings....one size DOES NOT FIT ALL.

      Wanted to see who was using the Equinox for prospecting and if you are, woudl you be willing to share settings and some find photos for the new Equinox Handbook that is getting ready to ship to the printer . . . will send a copy of the book when they come in if we can use them in the book.
      Send prospecting find photos or settings to asabisch@att.net
      Thanks in advance,,
