Finally picked up my new toy while in Adelaide at Easter , Had one go at Christies beach for 30mins , got first coin within 3mins $2 , then 3 $1 coins no can lids or foil !!! Just one small peace of iron near a fence!! Happy with that, had it set on STD coins ) , back in Geelong and down at foreshore nothing but frustration !! Could not stop it going haywire !! Gave up !! Down near bells beach yesterday , had control for first 20mims !! ( 2 $2 coins and a $1 coin and one star sinker !! Then I seemed to have probs with balance ? Not complaining with the gold coins !! Just seems strange I have not found any other coins , besides the ten cents I found when I tested my home made sand scoop in my back yard !! First scoop ( no detector ) gave it a shake and had a laugh when I heard then saw a coin at the bottom !!! Bloody oath it works I said !! Any tips ?
