Well... it arrived yesterday, From air test, my comparisons in my test garden, and taking it to the beach this morning these are my observations:
First and most obvious characteristic is that it is painfully unbalanced, all the weight is on your hand, my elbow was burning in pain after about 30 minutes... the Minelab F3 which is heavier but is so much better balanced, feels half the weight of the CMD while on the arm, the Infinium feels like a feather compared to both of them...
It's pretty sensitive for a VLF, but not quite as sensitive as the F3 or Infinium in my hot ground. Gets about 2" less depth than either Infinium or F3 in air and in ground difference seems even bigger. The depth difference is most obvious on smaller gold. Hits a nickel pretty hard though, about the depth of the PIs in air, but not in ground.
Ground balances fine on hot ground, very stable.
Uhh... headphones work well...
Conclusion:
It is essentially a VLF that works like a PI (no tones/no disc), can sweep it fast, and it covers a good amount of ground per sweep, but I'll take the extra sensitivity and depth of the Minelab F3/Infinium over it any day. The weight balance is a killer, after 2 hours my arm couldn't swing it anymore... my arm is shaking as I type this...
It isn't a bad machine, but when I'm comparing it to the F3/Infinium, which granted are going to be hard machines to beat, it just doesn't compete performance wise. It's only advantage is sweep speed and a little more coverage when compared to the F3, but less than the Infinium, at the cost of depth, and sensitivity to small gold.
I was hoping that it would be a winner on small gold, but that doesn't seem to be the case. Going to test it out some more, otherwise it's going back on ebay...
Oh well, was worth a shot, hopefully I can get most of my money back...
