hi all

i have recentley bought a scatt usb professional to shoot in the house over 4 metres. the problem im having is that im shooting over 4 metres but the computer seems to think that im shooting at 10 metres so all my movements and shots are greatly exagerated. to put it simply im taking shots which i know to be nines and tens but the computer says im hitting sixs and sevens, and not in groups either, they are all over the place. does anyone know how to set up the scatt so hat it realises im shooting at 4 metres?

thanks alot
