While it may be a fun project, night vision scopes are the last thing you need for successful coyote depredation.

Calling coyotes is very effective (electronic calls if legal) and you can also spotlight them (if night hunting / depredation is legal).

Be careful to check that there are not other similar looking animals that are protected (wolves, foxes, neighbor's mutt), especially when you hunt in low light or shoot long distance.

You could get your hunting guy from CA to start hunting the coyotes. Make it part of his access requirement to keep the predator population in check. This is not an uncommon request from landowners.
