    Nice bird,   'Champion?'  What's under the cowling?   Gravel bars do create opportunities.  Thanks for sharing.

    That there my friend is an Maule m4 with 210 hp engine alot of horse power needed to get to those hard to reach places. That's my friends plane.he can bring 800 pounds of gear with 2 people

    You notice there are two people and one of them has the gun.  When I went backpacking Alaska with my buddy, he started razzing me saying ... "what are you doing with that gun?  That .40 cal isn't going to stop a bear."  I told him that he was correct, it likely would only anger the bear.  But it doesn't have to stop a bear.  It just had to slow *him* down.  He gave me a blank white stare. True story.

    My friend was packing too

    Hmm, I thought we had a deal going to get my like new rockerbox to Bethel for $450 which included that water pump in your photo?

    $20 wasted on packaging expenses now...

    Sorry. I dident know a box cost 20 bucks. I would of got it but taking a month to get here was not my plan got this from wyoming i belive 3 days all for 480

  4. the rocker would of cost me 1200 to get it to bethel alaska

    so i got the micro high banker and pump for 600 

    so my plan is to have my partner pump as i add dirt or bring a car battery but i need to save on waight as the bush plane only allows 800 pounds

    the pump pushes out 28 gallons a minute

    the bilge battery operated pushes out 22 i hope it works

    I am one of those that hold absolutely no importance on air tests at all when detecting for gold. I don't rate them out in the gold fields at all.  After all....you don't find gold nuggets floating around in the air out in the gold fields. You have to dig for them. So what is the point of air tests? Depending on their orientation in the ground you will always get a stronger deeper hit on a piece of gold that has been laying in situ for a zillion years in the ground than if you buried the same nugget at the same depth, in which case you would probably not even get a hit at all. A nugget that has been laying in the ground for a zillion years develops a "halo" effect in the ground surrounding it due to impurities leaching & "rotting" out of it over the years & being absorbed by the ground surrounding the nugget. This is caused over time by a combination of acidic agents from water, plant matter, other minerals in the ground etc that the gold is subjected to. This "halo" along with the gold nugget gives the detector a bigger target to hit on than just the gold nugget alone. Once this is dug down to & the ground "halo" broken up, the signal can be somewhat reduced if the coil is still at ground level & not down into the hole. Sometimes it can even lead to the signal being lost if it was on the fringe of detection in the first place. So that is why air tests mean absolutely nothing out in the real world of gold detecting.

    Sourdoughmoe: Steve H & phoenix hit the nail on the head & I am sure they have given you your answer.

    Good luck out there.

    Thanks for the tips too, i did not take the halo affect into consideration.

    Completely depends on the nugget and the timings selected. Gold detectability varies a lot due to size, shape, and purity. Further, all PI timings have weak areas near the ground balance points in the timing schemes referred to as “holes”. Any nugget that’s composition puts its signal near one of these holes will have a weaker signal.

    Comparing nugget signals is a waste of time. The best you can do if you think your unit is defective is compare depths with the same coil and exact same settings on a nickel with somebody else that has the same rig.

    I get the idea you are new to PI and think they “go deeper” than VLF detectors. The reality is more like PI detector’s lose less depth in highly mineralized ground. In many Alaska low mineral / small gold situations there is honestly very little benefit in running a PI beyond the ability to run oversized coils. The vast majority of the gold found at the Ganes Creek pay to mine operation while it was running was found with VLFs like the MXT or X-Terra, not PI detectors.

    I very much doubt there is anything wrong with the detector - GPX machines are highly reliable. Coils do have more variability though and it’s hard to rule out coil issues with any detector.

    Steve your right it has to be the nugget and a low battery. I swaped out the battery and put a nickel 15 inches deep and it screams i belive i would be able to ping it 2 feet down, but i had to end the test due to permerfrost reasons

    I can hear a nickel 12 13 inches down its not screaming nor is it quiet its almost on the edge of quiet. Keep in mind all targets are buried

    That seems shallow to me as well. 2.5 grams is a fairly good sized chunk. I've never measured any recoveries so I couldn't give you any objective observations on how deep that coil should pick up that size of nugget.  I have recovered a couple of ounces of nuggets with that coil of various sizes and, subjectively, I would say that seems shallow to "just barely hear it". Do you have a nice stable threshold in those settings? You're not set to "Quiet" under "audio settings"? 

    Give it a try in Enhanced.

    Super stable i mean i let it purr. I can g

    Hear a nickle 12 13 inches down just fine
