  1. My understanding of Recovery speed/Reactivity is that it is actually a Ground Filter. It functions by adjusting the detectors response to how quickly it reacts to changes in the receiver's field. Mild ground's signal response changes slowly, so you can use less filtering. Highly mineralized ground changes more rapidly & requires more filtering for stable operation. How this same Recovery/Reaction control also effects actual target separation may or may not be be incidental or intended. Someone like @Geotechwould have to explain it for me. What I do know is that in my experimenting with the Legend and my other detectors that have this control, it makes a noticeable difference in having it set to match the Ground. More so than trying to separate closely spaced targets. The deeper the target and/or the worse the ground, the more important. The difference on the Legend is not as pronounced as on say the Rutus Versa. Each detector seems to have it's own sweet spot on sweep speed vs Recovery setting. At some point you can out swing a low Recovery setting. On the flip side, you can shorten audio response or limit detection depth with a fast Recovery setting to the point of over running good targets & never hearing them. You really just have to spend time experimenting with all this if you want to understand the detector at these kind of levels. For the Legend, in that days test bed conditions, Recovery 6 seemed to give the best response. 4 was not quite as good, nor was 8. 5&7 were pretty close to the same as 6. On my similar field sites I usually just go with Recovery 6 for non busy areas and listen closely for targets & changes in the ground signal by using NO Disc at all. Higher than Recovery 7 really cuts the audio response for me and kills depth sharply. As far as Ground balancing, my understanding is that a SMF detector typically uses a low frequency out of the simultaneous group to balance to & monitor the Ground response. Since a good effective GB is made on a target free spot, any subsequent change, whether from changing ground minerals or an actual target will give an audio indication. I think that what I was trying to demonstrate in the above video is an example of this. The small targets are being masked by the larger Ground signal to the point of being identified by the Legend as a ground response of TID1. In order to notice this, a good accurate GB needs to be maintained. My suggestion to @Nokta Detectors of adding a Hot Rock control would mitigate this effect by adjusting the detectors internal phase scaling. Sounds like your making good progress on you mining camp site. I have a few Hot Rocks but nothing like you are dealing with.
  2. Thanks Jeff. Iron Filter/Stability was at 1/3. V1.11 performs the same. The LG35 coil will perform better.
  3. You may very well be correct on a bad batch of coils, but Nokta will make it right, that, I am sure of.
  4. @HardPack, Lifting the coil should help on the hot rocks. I would recommend testing to see what level of sensitivity/depth loss it costs you on the type/size targets you are wanting to find. Trying to Ground Balance to the hot rocks if possible would help also, or even running a GB manual offset. Again, test to find what the trade off may be. Basalt would be a pretty tough environment. I’m thinking your ground conditions and mine are on on opposite ends of the scale. My TID 1 tone setup may not be practical for your conditions. You will just have to experiment. I’m kind of outside the conventional box getting into the weeds on the video. I hope it was thought provoking at least and maybe helpful to some.
  5. The Legend was my first SMF detector, and it has really impressed me with it's performance, especially on my mineralized relic sites. These are red dirt sites that I had worked over hard with Single frequency machines, to the point of seeming worked out. The Legend made them seem like new again. Now, 2 years later, the same sites seemed to be getting thin again. A second, different SMF detector, the Rutus Versa has shown that there were still good targets to be found. These have mostly all been small to very small, but a few larger surprises. It is amazing to me how different machines "see" targets/ground & report in their own way. This tells me there is no ONE BEST detector, and a site is never completely worked out. This is a good thing to me, because I like fooling around with detectors and learning what works & why. I have been experimenting on & off with ways to make the Legend perform better on smaller coin size targets in my red dirt minerals. One that shows promise is taking advantage of the Legend's adjustability to set up a special 4 tone audio profile. This profile is to capitalize on the fact that the Legend actually sees a smaller/deeper target in my mineralized soil, it just sees it, and calls it as a Ground response of TID 1. The special audio profile puts TID 1 in the first tone bin by itself, with a medium high pitched tone. The second tone bin is for iron, with the normal low tone & breaks at 7. The third tone bin is a normal mid tone, and the fourth the normal high tone. This works quite well, at least on my test bed. I have had some success with it in the field but need to do more hunting with it. What I really think @Nokta Detectorsshould consider is adding a Hot Rock control to the Legend. The Rutus Versa has this feature, and it makes a big difference in bringing out non ferrous targets that are being swallowed up by the Ground mineral response. By adding a positive adjustment, the TID scale is shifted slightly to bring targets back around to a non ground/non Iron TID/Tone. I demonstrated this in the first video I posted several weeks ago on my channel Red Dirt Detecting. Here is a video of the Legend, running thru the same test as the Versa previously. Please forgive the crudeness of my second only video attempt. I will try to improve in future.
  6. First impressions last a long time. I'm glad you are making the effort to put out some videos. I guess it all depends on what & how you want to portray. You could always make a disclaimer in the description.
  7. Nice hunt. It is fun to speculate & try to figure out why a "hot spot" would be where it is in a now wide open empty space.
  8. I know that is true, Sir. 👍 I actually find hunting in iron to be more logical. Al trash is just so all over the place. The darned older pull tabs will actually up average to a IHP range at times. I have never hunted a saltwater environment, just inland.
  9. Working in Iron trash is not a straight forward task. There are multiple variables and endless combinations. There also seems to be differences in terminology. Separation seems pretty plain to me. It is a matter of distance/ coil/recovery & coil control. Masking is all that and more. No matter what you call it, desirable non ferrous targets are influenced by the relatively “fat” signature of co-located iron. The co- located positions can be same plane 2D (rare), or some degree of 3D (common). They are both a matter of relative Signal response. The 3D factor is exponentially more crippling. You certainly can’t see these co-located targets in the ground, but you can make an educated guess based on digging a fair number of the iffy signals and some of the obvious small iron/nail signals. You can also successfully approach the site’s conditions by using techniques that are effective to some degree. If you want to have success, read & look at what competent iron sifters do. They learn, they test. They know detecting basics and they know their individual detectors like an old companion. Then, they dig those iffy hits you may very well walk right over. They also dig that big & mid size iron to get it out of the way. As far as “testing”, it is invaluable to me. It is how I come to know a machine/coil’s capabilities and limitations. Air/above ground tests are easy to setup and easy to visualize. They teach the basics plus things like down averaging of targets & audio signatures. In ground tests are more realistic. The more mineralized your soil, the more important they are. Target up averaging may show itself. In ground test targets are harder to set up but not too much so. You can visualize them with a diagram. This is where the post graduate education begins. Digging those iffy sounding compromised signals in the field, on your own sites, is the Internship that morphs into a career of being a successful hunter in the iron. This is from a relic hunters point of view, but applies to any type of hunting if the site is worn out. Digging some iron does not shame me. I don’t keep target ratios. I do find some neat stuff that surprises me almost every hunt. Tekkna, or any other specialty program can be great in the right circumstances, but they are special circumstances. I have used them myself. Now, can anybody give me some tips on hunting in Aluminum trash?🙃
  10. The double ring item could be a link for a chain pump. Nice finds.
  11. I was a little concerned that it might effect the battery life on my Garrett carrot but it has not that I can tell. It has proven to be a very handy modification.
  12. Excellent research results for an interesting item. That is half the fun and what brings the past to life, making it real. Thanks
  13. Interesting assortment of finds. Looks like George Washington on the spoon handle. Quite a few War Nickels posted on the forums lately.
  14. Welcome from East Texas.
  15. You could epoxy a rare earth super magnet in the recess. I keep a square of rubberized shelf liner with my spare battery for the Garrett carrot. It can be hard to remove the cap also.
  16. I have watched quite a few videos the last six months or so from some of the Eastern European testers. They have a somewhat different approach than we in the USA because their conditions are also different. Their ancient habitation sites seem to have plenty of very small iron bits, but not a lot of whole nails or the farm & wagon iron we dig on relic sites. The desirable targets they search for seem to be much smaller and of lower conductivity than ours. Still, I have learned a lot from some of them and can use it for my sites. In very heavy nails, their approach is helpful to un mask good targets that are being drug down by the co located iron. I still have to decide how small/low I want to go, but today’s machines can pull some surprising targets. Picking through the iron with a smaller coil and/or faster separation is a different game for different conditions. I want to have the ability to set a machine up to hunt the conditions I have. I don’t need to reinvent the wheel.
  17. That’s quite an assortment of finds. Glad you were able to get out on some different beach.
  18. The new Rutus Versa has 120 points also, divided up a little differently than previous models. It and my Whites MXT 180 point scale do a good job boxing in common Al trash. How a detector processes & normalizes the SMF signal is really the secret sauce on TID. The Nokta Legend only has 60 points, but has the most solid TID lock & accuracy out of all my detectors.
  19. Look’s like a fine day afield. Pretty Narcissus. I hate gnats.
