With Aldi selling their detector yesterday, it was a too good an opportunity to miss... So I went in and parted with $99 for the detector and around $4 for batteries. I took the detector home and put it together. Switched it on and ran it on "all metals". I ran everything from tin foil to a gold ring over the coil and it registered every item at distances of an inch to about 8-10 inches from the coil. I also ran it on "Disc" at around 7 notches and it rejected the tin foil, car keys, tin lid & cutlery. It picked up every coin from a 20c to a $2 coin. It was a bit of a hit and miss with 10c coins getting high pitch to low pitch tones. I didn`t have a 5c coin to try. The Gold ring registered but showed up as a ring pull on the meter but did not make the dull tone that it makes to tell you it was trash. With the milder weather next week I`m hoping to give it a go in the real world...
