Some More Sweep Speed Play On Deep Undug Targets Today, As Well As Seeing If Pin Point Mode Was Deeper Than Discriminate...

At the beach today on some of the super deep targets I tested more of the super slow versus faster sweep speed thing using the long general hunting sweep and not the short wiggle/sweep faster we use to pull the best ID/tone out of deep targets.

At this beach yep, super slow still hit just as hard on the target as the more normal Sovereign slow sweep, but it didn't appear to hit any better if I crawled, but just as good. Super slow meaning much slower than a normal Sovereign slow sweep...meaning only a crawl at mere inches at a time hardly moving.

So far 2 beaches did this, and 1 did not. At the 1 I had to pick up the speed to normal Sovereign slow speed to hear the ultra deep stuff, but at all 3 beaches a very fast sweep still hit hard on the target. And I'm talking Whites fast.

Very interesting so far, and I'm starting to think it all depends on the soil or sand as to if ultra super slow will or will not hit the target. I was thinking it was the coil choice but same 12x10 coil at all 3 sites. And today at 3PM sensitivity still a super slow sweep banged as hard on it, and I'm talking a crawl inches at a time here and it hit it just as good. But by the same token normal speed to super fast at all 3 did just as well too.

Very interesting so far. I'm guessing that if it keeps panning out like this for me in my soil/sand then ultra super slow won't always get the deepest stuff, while normal slow and faster will. Something to think about for sure, but more in field testing is in order.

The sensitivity being very low today at 3PM also kind of goes against the theory some of us had that a real low sensitivity needed a somewhat faster sweep to hit on the ultra deep stuff. Still need to see if a real high sensitivity means it will bang on deep stuff with a crawl better than normal Sovereign speed as many of us have speculated about in the past.

Also did some PP mode hunting since I've got my remote PP switch in my grip. Since the targets weren't all over I've been playing with that when they are not all over the place at sites. Thus far PP is fun to hunt in. In some cases it seems to make me notice a target that I might not otherwise hear in discriminate until I get the coil right over it, because when I flip to discriminate on some of the fringe stuff I need to be right centered over it to get a signal out of it once in a great while. I'd hunt in PP mode and then I flip to discriminate to see if it can see it and it always can so far, unless of course it's iron and it nulls out. And those are always shallower hits so I know it's not a deeper non-ferrous target that discriminate is nulling out on me.

Even though I almost always PP in discriminate mode, I tried PPing in PP mode on some deep targets today and it couldn't hear them. This has happened to me before, and is making me think PP mode on the GT is not as deep as discriminate, in my soil anyway.

Fun to toy with this stuff during the hunt and see the sweep speed and PP versus discriminate stuff play out, as it breaks up the routine of the hunt and makes you think a little instead of just let your mind wander while you listen for your next target.
 
Critter this may be true on the beach as I don't do any beach hunting as mine is all on land with most places are the parks, ball fields and schools that have been hit hard for many years is where I find the super slow speed will get signals even normal slow speed will not hear and dig some nice old coins. If I was able to do videos I would love to demonstrate what I am saying as the Sovereign is seeing any piece of metal and takes time to recover after seeing each one and being these deep signals are so small as i am sure you have seen on the deep ones a faster sweep speed you will not hear the threshold even change. Like I have said before this does work excellent in those area that are real old and been worked to death by others as most of the clad and trash is gone so you can listen close to hear them instead of getting blasted with the high audio.
I do feel for me I get more depth in disc than I do in all metal pinpoint, but I know some feel they do better in all metal pinpoint, but I run slower and run high sensitivity can be why. The sensitivity is mostly at 10 O'clock position and adjust my sweep speed so I can hear the threshold coming and going. Many targets i get my slight tone change in disc going slow i will not hear in all metal pinpoint and have to pinpoint the best i can in disc and with the help of my Sun Ray S1 probe able to find them after I dig out a deep plug. I have used these setting here in different parts of ND and SD and been in several different areas of MN and it has worked good for me.
If you or anyone feel the faster swing get better signal on deep targets on land you should use it. I will use my super slow speed in area that are very old and been hit hard over the years as I have proven this to me and others in my area these areas hold some deep coins. Those same targets when swinging over at just a slow speed are just a null as the Sovereign don't have time to see it,

Thanks Critter and Rick, I find all this very interesting. Maybe what I feel is slow and what other's feel is slow may be very different speeds (speed being a relative term). Critter, you mentioned "Whites speed" I came from a Whites to a Minelab and maybe thats where some of the confusion and/or different opinions come from. I had to whip the XLT around pretty fast to get the best performance out of it, not so with my GT. Sometimes trying to convey what you mean in words on a computer don't alway's come out the way you mean it. So maybe when I or someone else say's you need to go slow maybe i'm not going as slow as I make it sound. I also wonder about the the targets at the beach and whether or not having been dropped recently (assuming they are new drops) has an affect on sweep speed. I live in MN and Rick stated that he has hunted here and is adament about slow sweep speeds and that's also what I have found. I hunt in parks and ball fields just like Rick and for the most part our dirt is rich black dirt and is easy to dig in, making coins capable of sinking pretty deep making Rick's method very effective as I have found out. Different speeds for different folks at different areas.
Good luck Gary
 
These were targets at fringe depth below the normal sand and well into the black layer underneath by about 2" or so. Some of them were also round tabs, so both indicate they were targets that had been there for a long time. This beach isn't subjected to waves or water being that it's a small fresh water lake, so I bet they had been sitting in that blacker/deeper/compressed layer for a long time.

For sure got to play with this more in the field as well. I'm betting it all comes down to the soil mineralization for the most part, but that coil choice or sensitivity setting might have some effect too.

I have read in the past that some with the BBS and FBS machines using them in very neutral ground (which is rare) state that they don't get the depth performance typical of a Minelab, appearing that they need somewhat of a ground load to perform best. That kind of jives with the reports of poor air testing in some instances. Lucikly it's somewhat of a rarity in most areas of the US to have very neutral soil, as most soils have some level of mineralization.

I'm going to try to do some videos on this to show the sweep speeds I'm talking about and how PP often can't see a deep target for me while discriminte does sooner or later here, and on undug deep targets so there is no variable as to it being disturbed ground.
 
sweep speed is usually site specific....... sometimes slow is the way to go and recently during my summer vacation i had one evening where a faster swing speed was actually hitting targets much better than slower sweep speed...i know this goes against conventional wisdom but i would not have believed it if i didnt experienced it for myself.....i found a tungston ring 14 inches deep with a fast swing.... while on my beach vacation i noticed another excal user swinging his excal fast....every day i saw this guy he was swinging fast.....i also noticed he was doing more target digging than anyone else .....this made me wonder why this guy would be out there every day swinging as fast as he was until i tried it for myself....i got down to the end of the beach and turned back now swinging over the same areas i had just hunted....so i figured i would swing the coil as i double time it back up the beach....it was at that time i started hitting targets in the same wet sand myself and others had just hunted with little success......i found 3 rings that night in a half hours time which amazed me ,however the only gold i found during the week was several days prior when targets were few and far between and i was swinging at a snails pace ..... it just doesnt seem like deeper gold likes a fast swing speed,but thats the crazy thing about this hobby ,just when you think you have a perfect understanding of how your machine will respond ,you learn something new......
