In barns or other shelters under roofing where GPS signals are generally bad, a Nofence beacon should be used. The reason for this is that poor positions can lead to audio warnings and electric shock inside the building. When a collar registers that it is in contact with a Nofence beacon, the fencing function will turn itself off.
The reach distance of a beacon is approximately 10 metres but depends on physical obstacles. You will see the Bluetooth symbol in the app if the collar is in contact. To check the reach distance at the relevant site, you should walk around with a collar in your hand and observe the green diode to see how it makes contact with the transmitter. Three rapid green blinks indicate that the collar has just made contact. The collar will blink every 10 seconds thereafter. Be aware that the reach distance will vary depending on several conditions including if a goat is heading towards or away from the beacon, or if there are concrete walls/other obstacles.
You should consider using more than one beacon in larger areas. You might also use beacons outside buildings where the goats lie against the walls. Observe how they lie and evaluate the location of the beacon.
The Beacon is also important to reduce power consumption in the collar.
Be aware that if a beacon is located close to the boundary, it will be perceived as a ‘dip’ in the grazing pasture.
