KD0CAC Posted December 10, 2020 Share Posted December 10, 2020 I started detecting in the 80s mostly with dredging for gold , then left the gold country and ended up back in MN , got some more detectors with the intention of going back to northern CA - but dredging is outlawed [ bs ] and bought a bunch of detectors in the 90s and worked mostly parks & beaches walking the dog . Had a fire about 5 yrs. ago and lost about a quarter million in tools , equipment and about 6+ detectors . A little over a year ago , bought a Nox 800 , mostly did the FL beaches last winter , not sure if going back this winter . But I have been mostly doing beaches here in MN since coming back from FL just at the beginning of the codvid thing . 1st problem seems to be is most of the beaches I grew up on have replaced the sand beaches [ dirty dogs ;( with grass , and have been worked over / detected , but I still find enough for fun . 2nd issue is a good one , too many targets , that includes pull-tabs & bottle caps etc. , along with lots of coins at least $1 -$2 + per hour , not including jewelry - not much of that - this is where the amount of other stuff - money & pull-tabs & bottle caps - being older 67 , my arm / shoulder can only last about 3-4 hrs. , the space between all targets is most commonly about every 3" - 6" at least 70-80% of the time / area , and many multiple targets on top of / or right next to each other - having to pickout the trash to find coins . So finding jewelry is hard - have to dig lots of trash - to make sure I do not miss the googies . 3rd Now this is just theory for now , need to bring a kid out with me to do , what is very hard for me [ 3 different back injuries ] digging - the theory being that lots of coins going down 6"-8" and nothing older than about late 60s / 70s , so the idea is to have a young slave [ never did get around to having kids 😉 to dig a large area , maybe at least for testing 4' - 6' square and guessing at least a foot deep + --- to find silver coins . This should work good , because this area does not seem to have been found by other detectorist , I have never seen so many targets / coins . Oh this is a river that in the summer there are hundreds [ really ] of boats every day , and weekends it's almost bumper-to-bumper , and all the sandy areas are crowded / over crowded , lots of islands also , so have to have my friend drop me off those with his boat - while he keeps throwing fish back 😉 Now when I get the Nox 800 even just a little figured out / use to , too many hobbies , need to take time from other things to up to speed with the Nox . 4 Link to comment Share on other sites More sharing options...
FloridaSon Posted December 10, 2020 Share Posted December 10, 2020 Interesting idea, Tom Dankowsky did something like that but sifted the dug soil. It is an interesting read link below. If you are digging it up anyway, dump it into a screen and detect the ground as you planned. https://www.dankowskidetectors.com/painful_truth.htm Give it hell.

That is very high trash density. Have you tried the 6" coil? Less ground coverage but compensated for by fewer co-located signal headaches. 1 Link to comment Share on other sites More sharing options...
KD0CAC Posted December 11, 2020 Author Share Posted December 11, 2020 It would be a big legal issue I'm sure , this is in a town that would take issue . And maybe involve the feds , a good river - for federal water way . But had the idea of one of those walk-behind tracklaying bucket / diggers and shovel into a sifting system , claim I'm cleaning the beaches , kinda like the beaches in FL . And getting the other 2 sizes of coils for the Nox is on the list . But with so many targets , needing to use more functions of the detector to get good enough to dig mostly good stuff / not much trash . I thought about using my phone and making a video with sound to show how much more busy the detector is than I have ever seen or heard of .
