I thought this one would be good to share, found with a GP3500 with all the new mods that I have done recently.






Hi Peter, I thought you would be interested in, Steve who visited me today. He is a novice who purchased a 3500 recently. I advised him to have you modify the detector which he did. He went detecting recently in a well detected area.  He got a signal over a partly dug detector hole. It seems as if the previous operator had stopped digging thinking that it was just a ground noise. However,  the superior depth of his modded GP 3500 told Steve it was metal, so he kept on digging until he unearthed a 30 ounce nugget! It was a spot that had been well detected. I  visited that spot a few years ago and avoided detecting there as it was so obviously so well known and detected. Steve said that he is finding much more gold since he had the mod done.
 
Any way, I have attached a photo of the nugget which can be shown anywhere you like.
Cheers

I think that the Gold finds are going very well with the modded GP series but some of the feedback on the modded 4500 detectors is also very good.

No other info, it was found with a GP3500-M and its a big one, now the GP3500-M owner has paid for the mods...
