THIRD GENERATION GPS FENCE – F840 XSentry
The latest advancement in GPS containment systems, the F840 XSentry, introduces groundbreaking features that set it apart from previous models. Equipped with an upgraded chip for superior GPS signal reception, this advanced fence ensures greater stability and precision even in challenging signal areas, making it the ultimate choice for reliable boundary containment.
NEW DUAL-MODE FUNCTIONALITY
The F840 XSentry offers a significant upgrade with its new Fixed Mode, in addition to the Auto Mode available in the F810. Fixed Mode allows you to manually adjust the warning strength, making this system suitable for dogs of all temperaments, including stubborn or hard-to-train breeds. With this level of customization, the F840 XSentry provides optimal boundary training tailored to your dog’s unique needs.
AI INTELLIGENT SCENE RECOGNITION
This innovative model retains the Intelligent Scene Recognition technology introduced in the F810, allowing it to detect whether the environment is indoors or outdoors. This feature eliminates false triggers and ensures precise boundary control, giving you a seamless pet-containment experience.
FOR AREAS AT LEAST 1 ACRE OR LARGER
Designed for spacious outdoor areas, the F840 XSentry covers a circular boundary with an adjustable radius ranging from 99ft to 3300ft (33–1000 yards). Please note that this system is unsuitable for small yards, indoor use, or densely wooded spaces.
ADVANCED SAFETY FEATURES
The collar activates progressively increasing tones, vibrations, and/or shocks across six levels when your dog approaches the boundary. After each cycle, there is a one-minute pause before it restarts. If your dog doesn't return, the collar will emit a continuous beep until your pet is back within the boundary. This ensures safety while avoiding overstimulation.
SUITABLE FOR MEDIUM TO LARGE DOGS
The F840 XSentry is designed for medium to large breeds, fitting neck sizes from 9 to 23 inches. Simply trim the excess strap for a comfortable and secure fit. This product is not recommended for small dogs or puppies.
