Good point on the UK videos. Their soil is vastly different from what's here with a lot of the south of England being sedimentary.
Done 8 trips over and will round it off at 900-100hrs of digging time total.
Probably could come up with a pretty good # if I reread the daily diaries on my hunting trips.
But I have found heavy clay is heavy clay, sandy loamy soils are similar also.
Though what works is that a lot of the fields are still turned over there every 5 yrs or so.
No till here is a tickle of the top few inches and at most a discing it seems.
In the northern dirt we have the chance of frost moving the soils around some so returning to a site after a few years still brings around a target or two.
Deus fast-still means swinging the coil slow if the area is saturated with targets.
Even out on the fringes of the site in the wide open field I can swing faster and hear the slightest of a chirp, stop, rescan the spot and I'm surprised at the increased sound/ID of the target.
Seriously every site usually has small brass targets, bits of harmonica reeds, .22 cal. short/long, bits and bobs of things that are smaller than a dime, if I am not digging small then I correct my speed to start digging small.
Even after swinging for 5 decades I get carried away with the need to cover it all quickly, which is ok for cherry picking, seeing the parameters of the actual site.
I tend to think you have hit the nail on the head being tall/short Smokey. Being 6'3" me legs can stride a whole lot, but I have that thing of coil scraping or just touching, parallel to the soils, (not heel touching-or what a dragster is doing in the 1/4 mile takeoff), OVERLAP!OVERLAP!OVERLAP! the coil swing. Many yrs of trying to perfect these simple over looked facts will miss targets. 1"=missed something.
Bad habits: Get signal dig set detector down, coil 'shaft bolt a tad loose coil adjusts angle, start detecting, coil doing the 1/4 miler=missed something.
Get up start detecting just ahead of where I stopped=missed again.
Gridding-get to the turn around and start the next row=missed part of the corner=missed another one.
No wonder there are so many targets in a hard hit site.
Seen it on trips where the question would be asked or person stated that there was only a few pieces of lead in a field-it sucked.
Walked onto it and found that there was a fair site just over a tad, could have hit with a rock throw...
That's what I love about this hobby is the getting the missed ones.
Then again I have walked through a large field and found it so quiet it sucked my brains out, arm just a burning from swinging and not digging.
Yet later on many Celtic golds were recovered off the same dirt....1" might as well be 1 acre.....Missed them all.
It's the pace not the race that scratches the itch many times.
