new mod settings on 4500

(1/3) > >>

shepcal@sti.net:
Getting ready for second trip to Q for this year with latest mods on my 4500. Last month there, I did as you suggested- went to factory default settings, run in normal, set rear gain at 5, was able to set front gain almost at max. I noticed I was able to lower threshold to 11:30-12 o’clock and still have smooth threshold (before, I needed to run at 1-1:30 to be smooth).
   I’m running the 12” EVO coil. Quartzsite is pretty neutral as far as mineralization. As suggested, hit areas I found gold before and dig up what I missed. I’m king of one nugget patches and when I find a nugget, I grid- no gold last trip. Being honest, wasn’t out for long days cause it was bloody too hot for this ol ass. My first target was foil at close to 2’ down (had to go back to camp to get pin-pointer to confirm it wasn’t in sidewall of hole and it wasn’t). Believe, I just didn’t over any gold. Dug some pretty deep small targets tho, slivers of lead, minute pieces of rust.
   The 12” EVO is all I ran last month. This next trip, I am going to start off with the NF 20” RM. My thoughts on settings: smooth signal is an absolute must! Low mineralization, so set front gain at max, back gain at 5, if smooth run back gain up a notch or two, when it gets a bit scratchy, lower front gain till smooth. When I work an area with the 20”, if I get a good target, I’ll mark and come back with the 12”.
   Any suggestions or recommendations?

I like the 20" mono its a good coil, i use to walk around detecting with it lapping my swing about half the coil. Than realised one day i was only giving my self only about 50% chance of hitting a big nugget at depth by doing that. Now when i use a big coil like that, i only increase my lap by a quarter or 1/3  so i dont miss anything deep at the narrow end, hey good luck in Q hope you find a bit.

I was out today playing with a 25" NFA Mono and comparing to a 15" FWE  and I am gobsmacked that the 15" could get far better response on 18" and 24" targets of various sizes.

I was at the Laanacoorie test site and I was really struggling to get a signal at 3'6" with the 20" mono, the 15" Evo could cot hear the target, a standard detector was hard pushed to hear anything at 3' deep.

Joeboy:
Gday what is a 15" FWE ?

woody:
Flat wound evolution.
