When considering what comes in the package, I felt that the manufacturer covers all bases. Along with the detector itself, I receive two AAA batteries, a user manual for clear guidance, and a lanyard ring for convenient carrying or hanging. The availability of 12-month product service and lifetime technical support also provides extra confidence that assistance will be available if I encounter any issues or questions down the road.
