Viper connect?
in similar circumstances, I use a hand held NV in the left hand and a lazer dot fitted CP1 pistol in .25 in the right hand. This is pest control though, and not 'sport' . The shed is a food storage unit where out of date products from supermarkets are stored to feed animals in a sanctuary. Poisons are not allowed and there is too much food available for traps to be really effective.
