Mark 2 VS Infinium

[SWMO Mark]

I was wondering how much depth difference there is between Garretts Mark II and the Infinium, useing a 8" coil. For use on non-mineralized saltwater beaches. Not interested in the tone ID. Anyone do any testing? Mark

Hi,

If it is non-mineralized and you do not care about the tones no reason to go Infinium. The Mark II will outperform it in low mineral soil.

Steve, I would be useing it on the non-mineralized beaches of FL. What do you mean by out perform? Depth, stability? Thanks, Mark

I would go Mark II if I were you. I have both. The Infinium was designed for gold prospecting with water proof design. Some people complain about it at the beach because it is SUPER sensitive compared to traditional beach PI's and it will be noisier than the Mark II. With the 8" coil you will get great depth on par or better in some areas as the minelab EXCAL machines. BUT... with the 10x14 mono you will surpass the minelabs EXCAL on depth. Plus the Mark II is cost friendly. Good luck!

Hi Mark,

Both.

The Infinium ground balances, the Mark II does not. Ground balancing adds depth in high mineral ground and robs it in low mineral ground.

In zero mineral ground the Mark II easily bests the Infinium for depth. Now slowly turn up the mineralization. The Infinium loses depth less quickly than the Mark II, so you reach a point where the Infinium now gets better depth. Not because it goes deeper per se, but because it loses depth at a lower rate as mineralization increases. I hope this makes sense.

The ground balance circuit also tends to introduce noise. So a stright PI unit like the Mark II is generally less prone to noise/stability issues.

Pure trade-off, and no way to know exactly where the tipping point is except at the extremes. I'm headed to Hawaii this weekend, and it has high mineral black sand beaches. I'll be packing my Infinium. So althoughI'm an Infinium guy I'm still saying Mark II for what you describe.

Looking forward to seeing your Infinium finds from Hawaii...!
