Rainguard® HD is a patented, permanent, hydrophobic, oleophobic lens coating that causes moisture from rain, snow, sleet and your breath to instantly bead-up into smaller droplets and scatter. These tiny droplets divert dramatically less light and keep your view bright and clear when an untreated lens would be rendered useless.
To create the ultimate optics, we knew we had to develop a solution to the fogged lens. We perfected this technology, and you'll only find it on select Bushnell® optics. Conversely, you will find a few imitators, some that require periodic reapplication. They work sometimes, or not at all. Absolute surety at the moment of truth is what Rainguard® HD is all about. Without it, you're not ready.
