Was just about to ask that. Been there, done that. .....in the nastiest salt beach EVER...more like a garbage dump. The best part is probably 10 people saw the scoop snap and my rotund body go flopping into the water. Not one person even asked if I was ok.
Haha...not sure how I missed this post. Certainly wasn't intentional but yeah, I also wasn't being my usual careful self. I do have memories of a large boulder or something that I really shouldn't have been trying to pry out of the bottom of a 3 foot hole...
What ?? And risk missing a tinsel thin gold chain or earing stud ? Say it isn't so ! But seriously, you're right. In such conditions depth becomes a non-issue. Speed of target recovery becomes the sole focus. Whatever you don't get now, and it's possible that spot on the beach won't be eroded back to those same levels, for 5, 10, or 15 yrs. from now.
There are occasions where you simply can't get all the targets , because the window of time is not going to allow it. So in this case it *is* wise to maximize your time. Heck, I've even been in erosion with targets so thick, that I actually start passing up all the high conductors, to maximize my potential for gold (rather than pesky pennies, dimes, etc....)
I built my PI around finding the deep small thin gold rings, jewelry folks miss
without worrying about digging 1000 pcs of small foil. Set the P Delay at a particular spot and the small foil is basically not seen the gold is.
My current version is a superb unit, it will pick up my gold wedding band at 12" using the 7" coil. It will not pick up wrought iron nails beyond 5-6", yet still sound off on gold if the ring is deeper and right next to the nail. Nothing extra ordinary, its just the way it was designed and calibrated. There's a few folks that have one of my previous version land units.....Gunnar own one and does post some videos about it now and then. He's still getting the hang of it. https://www.youtube.com/user/kaolinwasher/videos
That's why I say get the right PI for the job intended and put the time into it and learn how to use it. PI's are not for everyone.
