This newly designed line is based on customer research and market trends. Waterproof and rechargeable, the PetSafe Remote Trainers are easy to use and quickly improve communication between pet and pet owner. Available in 100-, 300-, 600- or 900-yard range, Remote Trainers include tone, vibration and 15 levels of static stimulation. Trainers in the Lite line include the same features but deliver a gentler stimulation than standard trainers, even at higher levels. They are best suited for sensitive, timid or smaller dogs.
