Great info and great help as always from signal line....thank you my friend!!!
Well, I had a 2 hours inland hunting (today), and another 3 hours in a dry pebble beach (yesterday)...
I managed some coins but not much (however, one coin from the inland hunting is an extremelly tiny old silver...I have to deliver this find in my local authorities soon and claim to keep it...it's just the law), and managed also a veeeery thin gold ring at the pebbles beach (my first one!!) with some clad coins also.
I was running 28khz in both hunts, 2 tones (202/710), with reactivity 2, silencer -1, disc 6, sens 95, tx power 2, audio 5, iron vol 3, gb manual.
Regarding reactivity: I'm completelly satisfied with reactivity @2 for seperation and depth (I made some extra tests and worked extremelly fine) so I agree with you...I'll leave reactivity as is @2 for now...it seams the best all around setting and I really like the tone length of it.
Regarding Deep platform: I have tried deep vs fast filters, but I gave up due to an incredible amount of iron falsing and chattering with deep....so I based all my programs in fast platform..it seems to me that fast platform is running a lot smoother and stable than deep.
As for 50/50 signals.....you gave me some great info...I had not put the depth into the equation to make my dig decissions for those 50/50 iron buzz/high tone signals. I will definetelly follow your advice and will pass only the shallow 50/50 signals that cannot isolate the high tone without a strong iron buzz. However, maybe my audio response @5 isn't the best choice to have a depth perception...I'm thinking that audio @3 would be a better choice to distinguish the usually valuable deep targets from the shallow junk, but I'm afraid that it should be more difficult to hear them with audio response @3...what's your thought on this?
Now...as I said before, can slaw and aluminum foil pieces are my biggest enemy so far. I was afraid iron as a newbie, but it seems that I don't dig much iron at all....only some rusty pieces now and then....but can slaw and aluminum pieces or foil, a real nightmare for me so far!
Imagine that yesterday, in the dry pebble beach 3 hours hunt, I managed to cover only 10 meters (!!!) of the beach as I was going forward at a coil-swing width....only 10 meters in 3 hours...!!!!! and that's because eeevery few cms I had a high tone that proved to be another aluminum piece...either foil or melted aluminum pieces. Yes, I managed a gold ring as stated above and some coins (not much), but the amount of aluminum pieces were at enormous quantities...I recovered more than 100+ of aluminum pieces in that little beach area, and that kept me going really slow for a 3 hours hunt.
Same today in inland hunting....a million of foil and can slaw pieces in the old church field and was tired very soon of digging them. thankfully however, I found the old silver coin so happy overall.
Anyway, I definetelly have to find a way for the tremendus amounts of aluminum junk I dig. I'm thinking that when inland hunting, to focus only in coin range signals (70+) and notch everything in can slaw and aluminum foil range...and yes forget gold but save my mentallity......but in beaches, where I'm searching jewelry, no way around aluminum I gess...so I will continue to dig everything and hope that aluminum doesn't drive me completelly crazy...
