Alpine's wind tester is designed to eliminate fumbling for your wind tester while stalking game. By hooking it to your belt or pack you can keep hand movement to a minimum and remain undetected by your quarry. It is assembled using a shock cord to give you additional reach away from your body to pick up subtle wind movements. Since the bottle hangs with the nozzle in the down position, your powder is always charged in the tip, and ready to go. The powder is dyed green to eliminate a bright white flag when puffing at low light.
