Bronze age axe head, one of my friends who has sadly past away found 4 or 5 and also half a bronze age sword. The more time you put in and more ground you cover the more likely you are to find something good.
Seen hammered coins, Roman coins, gold coins, sword pomells, viking silver, a Hitler youth dagger, Roman sling shots, lots of different stuff.
I use an Xp Deus based in the UK.
Acer are middle of the pack with hp at the bottom, dell and Lenovo are probably the best. Golden rule, never ever ever buy anything made by hp, problems after problems especially their printers.
I prefer Lenovo to be honest but dell are good as well.
I have been repairing computers for 20 years.
