Hi Steve and thank you. Hehe fishing is my passion has been all my life.
Thank you for the detailed reply. I fully understand and appreciate the settings out lined and have used them a number of times and will continue to do so.
Not confusing at all my friend taking it all in and I will follow up with regards to the article.
The reason I asked about the Lunk Z setting was because the target signal was inverted or reversed, which made the target leap out amongst the very noisey ground. Those settings also made a big difference to the amount of ground noise getting through, and where I come from it's all ironstone/iron ore. Matter of fact I had a ironstone rock leave the ground 3 inches and attached itself to my are earth magnet. Every sweep of the coil was a flood of horrible ground noise even had the gain turned back to number 2, which was impossible to turn out. The Lunk setting made a huge difference.
Was just kind of hoping such setting exists for the GPX.
Thanks again for your help.
Regards
Rob
