The all new 509 anti-fog fan, stops fog dead in it’s tracks. If you are a heavy sweater or just want an extra level of fog stopping protection, the 509 anti-fog fan is for you. This is a removable fan module that installs directly into your existing pair of 509 goggles. In fact this 509 version was specifically re-engineered to work with both 509 Sinister & Aviator goggles. No other fan product on the market is directly compatible with both 509 goggle models. In addition, it’s compatible with virtually every other goggle brand on the market. Once installed in your goggles, the fan module has 3 settings. Off, On, and Auto. The auto setting automatically detects fog and turns on the fan only when needed. Just set it on auto and let the module do all the work. The fan works by pulling moisture from inside the goggle and pushing it out the top of your goggles. When the moisture level drops to an acceptable level, the fan will automatically turn off. The fan is powered by one AAA battery, which is included.
Works great - put in lithium battery & run on auto mode. No more fog! Just bought a second fan for my extra goggles too! The only negative is in order to install new batteries you have to remove unit from goggles.
Hello All! I\'ve had one of these gadgets since last year… A great investment and worth every penny. Little fan clicks on automatically as soon as it detects moisture. Works like a charm, especially when you stop to check a map or pop into the gas station when fueling. Battery life is excellent as well… I only end up using a couple per season. Just bought a third one today for another pair of goggles… I don\'t like not having it! Just get one! Do it!
Used the fan over 5 times so far and never a fog or freezing issue. Before my 509\'s would fog some during hard riding and would have to be removed immediately after stopping or get worse. Just this weekend I rode with a 509 sponsored Polaris rider we discussed the fogging issue that he doesn\'t have and I use to all while never taking off the goggles. The fan works great just set on automatic and ride! 3 thumbs up!
