  1. First off I am getting the Simplex primarily as a backup for my fresh water wading.  It also has a chance to become my first choice as MF is not needed for fresh water hunting.  I have used many single freq machine in the lakes here, 12 Khz and high gain should get it done quite nicely which leads to why my request for the proper coil.   Wading for jewelry is all about area coverage, the more the better.   To cover larger areas requires time and at my age the size of standard DD coils is a time limiting factor due to the resistance of pushing those DD coils thru the water.  Looking at N/M's website they are already supplying a coil for the Anfibio/ZKruzer line that would fill the bill for me, the 9" concentric.  Less drag will extend my hunt time and the real kicker, the increased sensitivity to small gold due to the concentric design.  Please N/M give me my coil!

    If you don't mind answering a couple questions about your coin program, are you using any disc, or do you run with horseshoe engaged? How many tones also. 

    I run all metal all the time.  I believe I said 3 tone but its actually 4.  Foil 1 thru 11 low tone, nickel 12 and 13 high tone.  14-16 a mid tone, 17 and up high tone.  Vol 6 on the iron

    I was experimenting varying RS between 3 & 2 and IB from 4 down to 0. After the county sheriff arrived my concentration was shaken, even though he decided I was on my permission. I had no concentration remaining whatsoever when after the sheriff left, I had a concerned citizen honking his car horn at me. After explaining myself yet again, I was too frazzled to resume my experiment with F2. But my aborted experience with recovery 2 and low F2 coupled with your experiences, gives some clue where I'll start when my state of mind is right to go back to that particular permission or my next hunt in a different spot.

    I'll probably change up the Bias and speed site dependent but 2 and 2 was working well for me yesterday.

  3. It was fortunate that I had lowered the range of my high tone coin program from 18 down to 17 to hunt this particular site..  This was a couple days before the upgrade went on line.  

    Yesterday I hunted a different site that has some rotting tin like can lids and pieces.  I dug several of these and found that the smaller pieces will actually go to the iron tone by simply moving F2 0 up to F2 2.  That was a eureka moment for me.  I also dropped recovery down from 3 to 2 and the hunt in that area was a giant step in intelligibility for me compared with F2 0 with recovery 3 and part of that was due to the reduced fatigue factor.  Cleaner more coherent sounds akin to crappy loud speakers vs Hi-Fi.

     

  4. Flowdog I had pretty much the same experience hunting the nails where an old church burnt down.  Many many times I would get falsing that in my experience constituted a high probability of a non-ferrous in the iron only to be the iron tricking me.  These were not the grasping for straws that we sometimes go for, some of them I thought should have been non-ferrous.

    But then, F2 0 did it's thing when I got a nice smooth fainter yet quick high tone that stopped me dead.  I spent a lot of time interrogating this one.  luckily I had initially hit it just right as it was only discernible from a narrow sweep angle.  With a tight well centered sweep It gave a repeatable TID of 17.  After removing the plug the signal disappeared and cleaning the loose soil from the bottom of the hole gave the same result.  I loosened the soil in the bottom to a depth of around 8" and started running handfuls over the coil.  Eventually I had it in my hand, It was not the IH or junk target I had surmised but a 1916 wheat penny normal TID 22-24.

    Look at it this way. Let’s say you reject nothing and hear all targets, with low tones indicating ferrous targets. This is great for alerting you to target density and the need to slow down. I know in the U.K. in particular I wanted to know about an increase in ferrous target density as it possibly means an old habitation site.

    But maybe you hate getting machine gun ferrous tones. Using a threshold and blocking/notching out the ferrous now has a silencing/nulling of the threshold when you run across ferrous. You are replacing a ferrous tone with a nulling of the threshold. This may be more pleasant for some people.

    That is what a reference threshold is for - alerting you to the presence of a rejected target instead of not knowing about it at all.

    Since sensitivity sets the level of signal strength put thru to the headphones  blanking of the reference threshold can be useful as a gauge to reduce sensitivity and quiet things down in a busy iron site where you are in an almost constant null.

    It works especially well for me on the X-Terra but it's not the unmasker the Eqx is.

    Tom D is saying f2 at 4 is equivalent to fe at 0. So yes you were essentially running the same. Something else may be happening that i dont know about and he hasn't said though. But he said every number under 4 is the same as taking normal fe negative by a quarter. So that f2 0 is the same as if you could run fe at negative 1

    Tom's clarification was needed and welcome. It seems the F2 settings are his baby that he convinced ML to implement.

    So F2 4 and higher gives increasing levels of rejection of bottle caps and round iron.

    Settings below F2 4 give increasing levels of sensitivity to masked/tilted coins in iron at and increased level of audio fatigue.  I've used FE 0 since almost day one So will jump right to F2 0 and see if I can handle it in that bed of nails site comparing targets to FE 0 for sh@ts and giggles.

    The question on my mind is that blackened earth from the fire, will it have an effect on the outcome?

    Why the lower IB settings?  Did you try the default F2 setting of 6?  Were you in All Metal mode?  Why not compare FE 6 to F2 6 settings?

    I hunt with FE at 0 nothing else so why compare settings I don't use?  F2 4 was stated by Tom D to be the end all and for a lot of situations I'm sure he's right as he knows a lot more about detectors than myself. If the new F2 settings helped in beds of nails that would have been great, but they don't.  F2 apparently helps on round iron and bottle caps I'm sure a lot of people will like that.

  8. Went to the summer camp and detected where an early building burned to the ground, a bed of nails and a layer of blackened earth.  After comparing the "old" iron bias setting of 0 against the new F2 mode set at 4 I can honestly say there is absolutely no difference in audio or TID intelligibility.  None Nada zip.  Same ole falsing and jumpy TID.

    Can't yet say on iron rings or bottle caps but it appears the nail handling is not improved one iota.

  9. Not definitive by any means but did some test on my wooden floor with a nickel and an antique gold band I found yesterday at the summer camp.   In addition to the nails in the floor I added a rusty crusty bent nail to the mix. 

    The results surprised me! With normal IB at 0 compared to the new F mode there was no discernible loss of signal response/audio quality even with F mode cranked to 9 no matter the relationship of the position of the target to nail. 

    So it seems this feature may possibly be fine tuned to the response of certain unique targets as in bottle caps and flat iron?

    Can't wait to get out and try it in the area we hunted yesterday where the stock coil was smearing high conductors from 20 to 30 due to co-locate nails whereas my buddy using the 6"er was getting almost solid lock ons varying only a couple numbers when compared. He beat me with 2 V Nckels and a Buff to my none but we were even on IH's and I got him on the ring.

    Are you saying you felt the good targets were a bit cleaner after the update just on normal everyday settings? I ask because they mentioned that F2 feature being added, the backlight correction on the 600 and MUCH MORE.... I want to know what the much more is.

    I would like to know as well.  Hit an old summer camp yesterday and had quite a bit of iron falsing to high numbers with IB at 0. The negative numbers clue you in but it slows down the hunt.    If the rain stops will check it out in normal FE with IB 0 thru 3 and and compare against the new F modes.  Mostly interested in how it effect see thru (possible loss of targets) using the new F mode settings. 

  11. Pimento, I must have an unusual upper body to arm ratio or something then as no matter the length of the shaft I get no uncomfortable twist in my hand/wrist.  Weight and balance wise I keep my hand up against the bottom of the pod.  Water hunting I actually extend the shaft a notch farther than when land hunting. 

    OK now I see some twist... But only when I allow the coil to rise up at the end of a sweep.  I taught myself years ago to maintain a proper level sweep.

  12. Amazing find for the group and farmer.  I hope they do well on the evaluation!  The reporter seemed to have a bit of fun as  well, making for a good read.

    As far as that S shaft goes, how could it be better without the weight of a battery pack under the armrest? I think it would balance better with the middle shaft  rotated 180 degrees, putting the coil below the plane of the armrest and pod handle.

    Hold your EQ as you normal do with a fairly straight arm then hold it with your hand at the bottom of the grip with your fingers wrapped underneath the shaft around the bottom mounting bracket.  Now, hold it by grasping the control pod itself which puts the coil well below the plane of the arm rest to pod angle.  Which feels lighter and/or better balanced to you?

  13. I tried Tom's settings yesterday and compared to Park 2 with the same settings Park 1 was much smoother and more intelligible.  So I have to agree with Tom on that one.  Picked up a few coins and a silver ring in a well hunted spot that were definite good signals, so there's that also.  Based on yesterdays results the Park 2 Recovery 4 settings I had settled on for most of my hunting might well be history.  Will know more after today.

  14. Since this was posted, I have determined that most of these hits are a reaction to the ground.  Specifically, the wave patterns in the sand. They are gone when the coil sweeps away the little ridges and do not give a signal in Field 2.  Have seen this with several VLF's in a few lakes here.
