gp3000

Hey there fellow prospectors ,just bought a 25 inch nugget finder for my old gp3000 very noisy at the moment dose anyone know the best settings for this combo or at least some advice.

Hi guys I know these posts come up regularly on this forum but I'm thinking of upgrading to a mine lab and don't really want too go all out and spend 6k for a 5000 even thou it's the whole hog I'm serious but not that serious to spend that amount and is way out of my price range as it would...

Does anyone have any opinion of or hints ortips for use of minelab gp3000
