You're ready. Pick your exact EXIT hole when you shoot and you will be just fine.
I used to think "chipmunks?????" You'd have to get a bucket full to make a meal.
But then my wife pointed out our $1,500 dollar japanese maple ( we didnt pay that for it, but it grew to be that size and a beautiful shape) and the fact that chipmunks were undermining the roots by digging burrows directly under the plant exposing the taproot to the open air, and endangering its ability to survive.
A Magnus 1 took care of that nicely, in three successive nights. I deep fried the little suckers on wooden sticks and tried to eat em..but they tasted nasty!
