Beach Hunting Recovery Speed

Recommended Posts

I have had good success with the 800 using factory settings.  Lately, the beach targets have slowed down significantly due to fewer tourists and more detectorists.  Will a slower recovery speed give more depth and increase targets?  Let me add I use beach 1, all metal, sensitivity around 22.

Everyone has to figure out what works out on their beach, but I personally do not see recovery speed tied to depth,  in the 3-6 range. However no doubt the higher sensitivity you can run the better. I think Clive has pointed out how a "high" recovery speed  can stabilize the unit in salt, therefore you may be able to run a higher sens. 

Myself, I HATE a detector that chatters too much on the beach.  I find that the time period of the low tide and the ability to cover more ground[sand] FAR out weighs trying to scrub every faint signal/false signal on the beach.  In a 3-4 hr period I need to complete 1 1/2 mile section of beach at the tides lowest point, if my detector is chirping too much for me to do this, I will have left possible targets in the sand. 

Looking at my notes from last season there were 4-6 days in the 45 days I worked that no chatter/falsing would have been mandatory.

According to the manual...... only gold mode has a true threshold that can affect targets.   So..... basically its additional noise to be used to hear iron blanking. .... which you can do the same thing by turning it OFF and running the iron bin lower and using AM.   Which will give you more information and act like background threshold.

Recovery and sensitive are very similar.   3 can be chatty on a hard pan running at 18....... yet switch to 4 it smooths out and can allow say a sensitivity of 20.  But to me th higher the recovery..... the short the tone response.  In the Dry sand most of the time field 2 is a better choice depth wise than beach 1.   In or near the water .... you get a concentration of layers black sand..... which you can hear if you run N. to S. (which a lot of hunters do).   Beach 2 is a better choice........ but if you grid E to W WITH the grain so to speak beach 1 works better and is deeper..... and may allow running 3 and higher sensitivity like.... 22 or 23.   Big factor here is EMI.... which can reduce depth as well.

Just saw the ring....... wow cant argue with success..... great find.

Thanks DC.  It's always beneficial to get additional information from other detectorists.  Depending on how I feel, I run N to S and E to W at various times.  Never thought about alternating between Beach 1 and Beach 2 when changing direction.  Also your comments on IB and threshold have sent me back to drawing board.  To be honest, I never considered (or even looked at) the IB and threshold settings.

I'm just now beginning to realize how many different tools are available on the 800.  Back to the classroom for my next quiz.

Thanks again.

I've been doing quite a bit of beach detecting the past couple of weeks and was reaching for my other detector more than my Nox as I found the Nox was giving me broken signals on deeper targets with poor ID's, I was running the 12x15" coil, after my other detectors battery went flat I was using the Nox again and messed around experimenting with settings to try improve its performance, I was running Beach 1 with sensitivity at 24 and all was well except when I found deeper targets and even some not so deep targets, the signals were all over the place.  I had auto ground tracking on as the beach required regular ground balancing but I often tried balancing right at the target to see if it helped which it didn't.

After trying various things I found lowing the recovery speed to 4 was the best solution to my problem, it cleaned up the scratchy target signals / target ID's a fair bit and I was now happy with the Nox again....  Is a lower recovery speed better with the larger coil on the beach? I remember last time I used the Nox at the beach I was using the stock coil and didn't have this problem, sure it was a different beach and I don't often do beach detecting, I'm no expert by any means. 

My settings were all defaults on Beach 1 in the dry, Beach 2 in the wet with sensitivity at 24, noise cancel done although didn't seem necessary and I did a manual ground balance then turned on auto, Nothing else was changed except when I found lowering the recovery to 4 helped quite a bit.

Was this a problem with the beaches I was on or the 12x15" coil? Does it work better with a lower recovery speed?  I don't recall this problem with the stock coil on my last beach detecting trip.

Phrunt,

Only had the 15" since Christmas, so about 20 hours on the beach.  Like you, I was at first disappointed with sensitivity to coil knock, target ID/scratchy signals.  I lowered recovery to 4 in the wet and am now a happy camper.  In the dry, I run recovery 5 and am amazed how quiet it is and also the machine's ability to sniff out small targets.  Also have spent some time using Field 2, recovery 5 in the dry with pretty good results.  Usual settings are Beach 1, sensitivity 22-23, Beach 2, 22-23.

For me, targets ID's do vary from the stock coil, especially our despicable zincoln pennies which can register from 12 to 24.  I have dug some US clad quarters that registered -6 on ID at first pass.  After the first scoop of sand is removed, the signal is more in line with what I am used to seeing.  That could be because the target is deeper.  With that, I am pretty much digging every repeatable solid signal, even if it falls in the iron range.

I definitely need more time with this coil.  Sweep speed is slower, but covers as much ground as normal speed with the stock coil.  Beaches here are pretty sanded in so targets are few.  Got some storms coming in and hopefully they will strip off some of the overburden.

Will keep you posted.

Thanks, I've found target ID's have moved up a tiny bit with the 12x15", our $1 and $2 coins were always 21 on the Target ID, now $1 is 21, $2 is 22 which makes sense as the $2 is bigger but made of the same materials.  I prefer the ID change.  I will have to try recovery of 5 on the dry, I just went straight to 4 and was happy so didn't change it again.  I've used the 12x15" extensively at the ski fields and never had this problem, it only happened on the beach.

This behavior (large coil likes recovery 4) seems to be a fairly common observation.  I have heard others say the same thing.  This may be partially driven because you can go deeper with this coil than stock, so lowering recovery naturally tends to clean up those deeper targets.  But that is not really the case on the shallower iffy signal targets, so I can only guess is that they are otherwise more challenging due to their orientation or other factors.  It could also simply be that 4/5 recovery just happens to be optimal for this coil vs. stock and the 6" but I don't have solid technical theory on why that is the case.

      Can I reduce the sensitivity of my GPX 5000 but still keep good depth. 
      I'll show you the problems I'm getting in this video

      In FNQ Australia, there are a number of properties you can go on & detect for gold. Most places are pay to detect & are well set up for camping with designated areas set aside for metal detecting, if you are fortunate enough to have access to private leases & cattle stations with gold bearing country even better again. Up until today, I had access to one of these private cattle stations to prospect on. Unfortunately I no longer have access, this is due to the fact there are still people doing the wrong thing while on these properties. The rubbish left behind at camp sites and open detector holes for cattle to break legs in is out of control. On top of that you got fence jumpers & poachers running a muck too. This is causing huge issues for for graziers forcing them to close the gates to everyone & in most cases getting access now, is nearly impossible. 
      I can't express in words how disappointing this is for us guys & girls who are doing the right thing, only to be told you can't detect at your favourite spot anymore because of w#%kers ruining it for everyone. So the quest for a new spot starts again....  Take only gold and memories & leave only foot prints. So we will all have somewhere to look for gold in the future!

      Found this in P.A in family farm . Looks like a broke golden arrowhead . Not sure any ideas . It's was about a foot in the ground  solid the whole way through and very heavy .

      I was looking around the new Minelab website and I noticed they now say the Equinox is single frequency on Gold Modes, is this some sort of error or are new Equinox 800's coming without multi-IQ on their gold modes?  I found nothing wrong with MultiIQ Gold modes so I don't see why they'd change it.

      Detect Modes
      Equally adaptable for all target types and ground conditions:
      Park Field Beach Gold: Gold Mode operates the high single frequencies of either 20 kHz or 40 kHz to detect gold nuggets in mineralised soils.

      Used Cherry Pick settings from the Handbook for  a brief session in a local park.  Found a penny, the handle of a spoon.  If it ever was silver plated, that is long gone.  Then found a quarter-sized disk, a token of some sort.  It says "Where a kid can be a kid" on both sides and one side was stamped OTTS.ORG.  I  just tried that website and it is apparently closed.  There was a message to the effect to leave your contact info if you have any business with this site.
       
      Question:  is there something more than the Lesche Predator but less than a shovel -- a mini shovel, perhaps?
