The ZeroTrace PureION Field Generator, from Wildgame Innovations, generates a field of ion molecules designed to safely dispel human scent particles, which gets you closer to game. ZeroTrace provides continuous aircover around a stand or in a blind. An ultra-quiet fan spreads ion particles evenly. The unit runs for up to 6 hours on the included rechargeable battery pack, that charges through a USB port. The ZeroTrace PureION Field Generator comes with an adjustable, magnetic mounting bracket.
