I live in an area where we get a lot of bad weather, do the collars work when it’s extreme temps or precipitating?
According to the company, the Halo Collar 3 is waterproof, which makes it compatible for use in rain or snow. In general, weather should not affect the GPS signals and logged data. The only exception, however, is that any build-up of snow on the antenna should be avoided, as large amounts of water will absorb GPS signals.
