  1. I still have a Windows laptop that was loaded with Win7 and then upgraded to Win10 and the hardware is so slow I can only use it as a backup now.  The internet requires speed and video and the Google Earth needs a good driver ... I bought this Chromebook/viewer just for the internet.  

    It may be necessary for me to buy a new computer before I buy a new detector so that my research is more complete with the online tools.  This forum upgrade will still take time to feel right but we will forget about the old version in time and get back to content again.

    Hundreds and hundreds of keys and tokens. this is just some of my finds over the years.

    You have a lot of history there.  It could be 'documented' with a note of some sort.  You know about when and where you found them which will add value.  It could all add up to many thousands of $$ and enjoyment for a collector.

    It may be a tedious task but no one else can do it.  I would suggest making a 'split' with one of your younger relatives.  They post it online and they 'split' the money with you.  Maybe they get it all or ...

    While they are doing this they will learn about you, the family and have a money making hobby/business.

    I see history thrown away in our alley dumpsters and given to Salvation Army every day.  If it had a 'story' it would be of much greater value to the right person.

  3. I just came back from a beach hunt.  Mind you conditions are not right at the beach for a lot of targets so I took it slow and easy on the first few 'tests.'  I used B1, 23, 6, F2 0 and then saved F2 9 and switched back and forth on the find, during the dig and after recovery.  I would have to say that several of the targets were the same on both with the 15" coil.  Lead seemed very similar.  Before I got to the wet sand I had a target and the 9 clearly had an effect on it.  It kept it in the negative numbers and sound and it was a dry bottle cap.  That was the best test where I could see a clear difference.  If other targets had responded the same way I'd use some F2 but I found a jumpiness with it that would take a learning curve to interpret.  I'm familiar with 0 sounds and expected targets.  F2 9 will not be something I use often, maybe in a park but that would be all.  I tried a bit of F2 5 and it was much less jumpy on the little swings.  I just didn't feel like the time it would take to switch back and forth would be worth it.  I'd already have dug the target.

    I think I should try the difference between B1 and B2 rather than FE or F2.

  4. Depth to bedrock gold could be a big problem of course.  Those that dug down to pay layers would have an advantage over a metal detector but you have the advantage over the trenchers in finding a shallow source.  The maps I was suggesting would have been some sort of USGS (if you are in the states) or other maps of historical activity you could see on My Land Matters.

    Where (geographical area) are you searching?

    That, of course, is dependent on search mode, ground conditions (e.g., mineralization), ferrous and non-ferrous junk density, and the primary targets of interest (gold vs. jewelry vs. coins vs. relics, mid-conductors vs. high conductors...) and their depth.  I guess that takes me back to my preferred middle-of-the-road IB setting of F2 = 4 to 6 as a good starting point.

    Chase,

    I'm quite like you on my beaches.  I don't want to mask. (B1, 23, 6, FE2 0)  I dig just about everything and if I see a -3 or -4 and it is deep I've had the numbers move up as I get the target out. (A -2 is nearly always a hair pin.)  Sometimes it will be a corroded penny at 10+ inches.  I can't think of a specific valuable target now that was negative and became valuable but just by practice I think it happens frequently.  I'd have to video my hunts.  Simon and I used to talk about the negative first numbers and Steve has addressed that.

    So the FE and FE2 are only audio controls.  It doesn't change anything in the display.

    A target that fools my 800 is a bent tent spike.  My 3030 would make it sing out loud and clear but the Nox garbles it like a chain.

    One variable you did not list from above was the coil size.  Is everyone on these tests using the 11" coil?

  6. I was just on eBay looking around at some old purchases I had made and one was from Miner John.  I clicked on the transaction and I see there are some 'live' products available.  That is good to see after I understand he was wiped out by the fire.

    Has anyone tried this stand?

    I saw another stand on a thread sometime here over the last year that would fold.  Does anyone use a folding stand?

    I don't have a Monster.  I don't know how Minelab would let a detector be sold that twists and turns so much when you put it on the ground.  Every video I've seen shows this problem of securing it while you get the little nuggets out of the scoop.

    One of the most remarkable discoveries of the twentieth century is that some meteorites contain dust grains made around other stars that lived and died more than 4.5 billion years ago, before our Solar System formed. Stars only twice the mass of our Sun eventually turned into red giant stars and lost much of their mass as gas and dust. More massive stars ended with spectacular explosions called supernovae, and throw off much of their mass. Both kinds of stars return copious amounts of dust to the interstellar medium (the stuff between the stars), a portion of which formed new stars like our own, and we have recognized dust grains from both red giants and supernovae in meteorites. Each dust grain retains a chemical and isotopic record of the star around which it formed and by analyzing individual dust grains in the laboratory, we can study the interiors of stars in ways not possible by astronomy with telescopes. The study of stardust in the laboratory has led to new understanding of how the chemical elements are made in stars. Stardust was also not uniformly mixed into the solar nebula, the disk of gas and dust from which the Sun and planets formed. This caused small differences in isotopic composition among Solar System materials that have proven to be powerful tracers of the relationships between planets and different kinds of meteorites.
