Had a week off and spent it on the beaches of Waiheke Island , New Zealand with the aim of finding $100.. did that in the first three days. Found other interesting things too , a couple of silver rings, lots of foreign coins, an ipod. My longest hunt was about four hours which netted over $40.. so $10 per hour.. not quite the minimum wage.... so if I decide to live in a cave somewhere I could at least feed myself.. and buy batteries.
