Bought this metal detector for my grandson who had been disappointed with another he got from an auction website a couple of years ago because basically it did not work and went through batteries in no time flat (no pun intended!). What a contrast! This one has proved an immediate success in finding small coins under our back lawn including a minute old decimal half pence some 6-7 inches down. The crowning find so far though was a gold ring our daughter lost in the grass some 20 years ago and which had sunk about 6 inches down. Apart from the lawn's now resembling the aftermath of the D-day landings we are thrilled with this purchase not least because it keeps the lad off his X-Box for several hours at a time!
