Hope Everyone out there is doing Great--
I've been using Randy's "hunt by ear" method exclusively on my 305 and am getting pretty good at sorting out the junk from the real stuff--using consistency and the lack of ferrous sounds at the edges of the detection zone. As an adjunct to this approach, I started doing the following trick. I'm wondering if there is any validity to this technique and if it will generally be reliable:
1. On our super-mineralized Seattle beaches, there's lots of buried iron and, in general, it's a bit harder than on good old soil to clarify the real targets. Sometimes, due to inductive effects and eddy currents, you'll even see/hear a "very clear" TID in a given location--only to find out that a piece of buried iron 1 foot away is bending the fields and fooling you that there's some copper or silver where it's just not.
2. So, when I beach-hunt something that seems good by all other "hunt by ear" tests, I sometimes will try to verify before digging by using the pinpoint mode on the 305--which I have to say is very accurate. This let's me find the real center or centers of emanation, examine them for size and position.
3. THEN i do the following to double check: I will go back to mode 1 (no discrim at all in there) or all-metal and "sniff" over the center i found via pinpoint. Usually, if it is iron--it will read a clear -4 and tone accordingly, with no good sounds when i am right over the target. The centering via pinpoint is of course essential for this to work right.
4. In this way, i feel i can get a very accurate read before i dig. I the tones/TIDs DON'T change to ferrous and the location stays the same, chances I am good to go and it will be a real find when i dig.
What do you guys think? It seems to work well, but might not in all cases....and maybe I really am just a crazy newbie !!!
thanks!
