a very experienced bitch I used to lamp would always run the beam, even then shed overrun a squatter if he sat tight enough, rather than shine the beam straight up the field onto the rabbit and past it, hold the lamp in the air then shine it down on the rabbit using just the spot rather than the whole beam. Narrow it down from a 250m beam or whatever it is to a spot, once you and dog get the hang of it job done. Also when walking upto a squatter walk at it head on so it gives the dog that extra split second it may need...keep at it, you'll learn most of it yourself, I did.
