Out of interest have you tried the Coin and Relic timing on the GPX with a big coil. I found using that timing the GPX 5000 ignores smaller nuggets that it would normally pick up very easily in other timings.
I realise you want to ignore quite large targets but perhaps with a very large coil like the Nugget Finder 25" DDX coil which isn't a very sensitive coil to small targets in the first place combined with being a DD whereby you could enable iron discrimination and running in Coin and Relic timing it might be reasonable for the task at hand.
The coin relic timing using DD coil ignore very small nuggets but in non mineral areas. In a mineral soil areas the noise is to hard and the machine it’s unstable with bad ground balance.
It is an extremely difficult case for example of coin size being completely rejected so we can see a big target in depth. The iron discrimination it is not needed as military boxes are made of iron.

Finishing, I love my 5K that is for its perfect function and why it does not leave any target in a wide range of sizes within the capabilities in the depth.

Hello everyone from Greece,
Friend Kostas we have discussed together enough this issue of the big frames - coils, relic hunting in Europe as well as other countries that love Gpx operations in terms of ground balancing that really is an excellent work of Minelab engineers, no one denies this.
Logic says that increasing coil size we lose sensitivity to very small targets but also allows us to find a bigger target in depth.
A tip is to increase the distance of coil from the soil to lose a little sensitivity to small targets, but at the same time we lose and a lot of depth.
But this is not enough if we mention as the Gpx series including Gpz is machines built on the philosophy of nuggets, that is to provide maximum sensitivity to a variety of nuggets sizes and to the maximum depth.
I believe that in order to be able to work in the way you mention above for large target sizes as a military box, but at the same time they do not have enough sensitivity to the small targets in an area containing a lot of rubbish, it is quite difficult to achieve the reason that I mention above in philosophy of their constructions.
Perhaps it could be done with an extremely large frame - coil provided that the ground balancing as well as the EMI like a normal coil will operate.
I find difficult achievement for Minelab as well as coil production companies worthwhile, like Coiltek and NF.

Hello everyone, I am from Greece and I have a Gpx 5000 for about 7 years, having a few different coils in mono and dd and some accessories such as: carbon shaft, b&z booster with speaker, nugget buster headphones ... and more. It is a wonderful pulse machine with perfect gb.
In Greece, as in the rest of Europe, gold nuggets are not the primary research, we are interested in hunting relics and hidden treasures of gold coins, gold bars and more from the Second World War.
But, I can not understand why Minelab does not pay the necessary attention with the presentation of new models not to have iron discrimination, thus making the Gpx 5000, which has been around for several years, as the best option we could have.
This is a large customer market of relic hunters and I think Minelab would do well to give more importance to this piece.
The only thing for sure is that they would gain a lot from it.
Please I Would Like Your GPX 5000 Opinion

Unfortunately, as you know, the construction of a properly constructed frame / coil is not enough to achieve what we are discussing, as the machine itself can not do that. Only with some modification of the unit which I do not approve of unless it could be applied by Minelab itself.
