I was able to hunt for about 1 1/2 hours last night with the update. WAY to short to give many definite conclusions, but I definitely noticed a slightly different "personality" to the machine -- all in a GOOD way. Here are a few tentative points/first impressions...
1. Definitely quieter/less chatter. You can run sensitivity higher now, with less EMI.
2. Depth meter is improved. Still need more time to say exactly "how much," but I definitely noticed more accuracy.
3. I'm still trying to figure out if I notice more "modulation," on deep targets; I didn't hit the deep targets last night that I need to hit, to figure out if I can discern whether the tones are quieter on the deep ones. But, I DO think I noticed it being louder on large/shallow targets, which is a definite plus. Still need more time to conclude whether I notice any appreciable "louder on large/shallow stuff, and quieter on the smaller/deeper stuff" modulation improvement, that some have noted.
4. ID seems, as a first impression, to be more stable/accurate.
5. The tones seem to be a little more, I don't know, "descriptive," maybe? This is the hardest thing which I noticed last night to describe, in terms of "quantifying." I felt that tones were "tighter" maybe, i.e. allowing a more clear indication as to exactly what was under the coil. In other words, it "spoke" better, to my ears, in terms of allowing me to know what I was hearing. I didn't have to "work as hard," mentally, to decipher what was in the ground. Again, very hard to describe and quantify, but it feels more "refined," tonally.
6. It MAY be a bit deeper, though I need to dig many more targets to know for sure. I didn't dig any particularly deep coins, but I did dig a small- to medium-sized crushed aluminum screw cap RIDICULOUSLY deep (estimated over 10" deep, I didn't measure), that sounded solid. That definitely seemed to be a "deeper than normal" dig, but since it's the only target I dug to base anything off of, I will withhold judgement until I do some more hunting and testing.
OVERALL, BIG-time kudos to Minelab. The update process could not have been any simpler or faster, IMO, and there are definite improvements to be had with the update, to an already super machine (for my style of hunting, in my type of dirt).
THANKS, Minelab! Please continue the great work!
