Infinium versus Seahunter Air Test

Has anyone done a comparitive air test or in sand, between the Infinium and the Seahunter Mark 2 on a target ,both machines being fitted with the standard 8" mono coil?
Thank you,
Peter
 
Hi,

What John said.

I can almost promise you the Seahunter air tests better. Straight PI units usually do.

The Infinium is a ground balancing PI (GBPI) detector. The GB circuit hurts it in an air test. This means in pure white Florida sand the Seahunter may get better depth.

But throw in the black sands and the hot rocks and it is a different story. Now the Infinium has the lead. So basically you have to test in the ground. Which unit will do better depends on how mineralized the soil is.

John and steve will you guys please explain to me why you can not air test an Infinium. It might tell all of us what we are doing wrong. Such as swinging our detectors from left to right instead of swinging the coil From Right to left. I mean every one knows that you have to swing you coil from Right to left and if your swing it from the front to the rear instead of swinging the coil from Back to front.

Got to remember which way to swing these Tom Fool Things.

I also Got two brand new gunny sacks so some of us can go snipe hunting this year at Italian Bar. I got Tom M and Perry talked into going Snipe hunting. I am bringing plenty of apples so we can lure the buggers in to our tree blind. Got a few knew double DD Bull Blinds in mussy oak

Hi dray,

I did explain it, but I'll try again. You sarcasm would imply that you think we are feeding you mumbo-jumbo.

You can air test an Infinium against a non-ground balancing PI like the Sea Hunter. The problem is it proves nothing and at worst misleads people.

A pure PI like the Sea Hunter can get better depth than a ground balancing PI like the Infinium if there is no ground mineralization. My White's TDI and Minelab GPX-4500 allow me to turn the ground balance on or off. In air tests both will get more depth with the ground balance turned off. In ground with little or no mineralization turning off the ground balance can increase depth.

The Sea Hunter has no ground balance to activate, and the Infinium is always set to ground balance. In air tests or in ground with little or no mineralization the Sea Hunter will excel. As the ground mineralization increases, you quickly hit a point where the Infinium is on par with the Sea Hunter. Increase the mineralization more, and the Sea Hunter falls behind. On black sand laden beaches the Infinium will blow the Sea Hunter away. The Sea Hunter will also bang on hot rocks that the Infinium will totally ignore. So which does better 100% depends on the nature of the ground in which you are detecting.

When comparing units that ground balance against units that do not ground balance it is the nature of the ground that is all important and so it must be taken into consideration. Old style TR units do very well in pure white coral sands. But in mineralized ground they are pretty much obsolete compared to the current ground balancing VLF units.

So I air test them both and tell you the Sea Hunter air tests better. You have learned nothing but that if the ground is 100% free of mineralization then the Sea Hunter will probably have the edge. But such conditions are so rare as to make air tests worthless.

Air tests are like seeing how fast a sports car can go compared to a 4WD truck by jacking the wheels off the ground, flooring the gas pedals, and looking at the speedometer. In the real world the sports car wins on the highway and the 4WD truck in the mud bogs.

Oh yeah, it very well can make a difference as to which way you swing your detector. There are items that will hit left to right and not right to left. Working a saltwater beach parallel to the water can introduce false signals that can be eliminated by working up and down the beach.

Good post Steve, I did not know that about the Sea Hunter, I have an Infinium myself and an Excalibur. It would be interesting to know which other beach/water detectors have ground balance permanently turned on or off. Gives food for thought.

On another note, dd's perform better when swinging right to left as you can imagine. It would not be a good idea to swing a coil front to back either, sarcasm or no sarcasm!
 
Hi Bence,

The only PI detectors that allow you to turn the ground balance on or off are the White's TDI and Minelab GPX-4500. With ground balance turned on, the TDI features manual ground balance. With ground balance turned on, the GPX-4500 features either automatic ground tracking, or fixed/locked (locks in last setting as determined by the auto tracking). The Minelab SD2000, SD2100, and SD2100v2 all are manual ground balance units. The SD2200, SD2200v2, GP Extreme, GP3000, GP3500, and GPX4000 all are automatic or fixed/locked units.

The Garrett Infinium always ground balances, either via a fast or slow auto track, or a fixed/locked setting. The Eric Foster Goldscan 5 series also always ground balances via a manual ground balance.

PI units that ground balance are rare, and the above are all I'm aware of. Units like the Garrett Sea Hunter, Tesoro Sand Shark, White's PI and PI Pro, Fisher Impulse, Foster Goldquest, DetectorPro PI, and so on are are simple non-ground balancing PI units.

Thanks Steve, very interesting indeed. The Sea Hunter 2 might just be a good compliment to the Infinium, or the Tesoro SS or the White's dual field. This helps catagorize detectors a lot better.
