Review:
The Petsafe PDT00-10675 is a great entry level remote trainer for the individual who wants basic commands and control over a larger dog.  The hand held transmitter is simple with few buttons to master, while still effectively having the ability to control your dog.  The operational range of 100 yards covers the distance many pet owners would use  trainer, to help visualize....picture in your mind the length of one football field.
