having used most of the modern detectors I purchased this detector from a friend who had one for sale and said a great detector for notching out rubbish ,I tried this out as well as no notch ,this is the haul of coins and bits found in two 4 hour sessions on a grass car park,in the UK about 80 dollars worth ,soon will have paid for it, the notch gets rid of foil silver paper small penny coins and leaves the better stuuf to dig ,seems a 20 year old detector for this type of coin shooting is better than the costly detectors of today .
