Hammerhead Bike Navigation

Make getting where you're going easier and safer — whether you're commuting to work, or meeting up with friends for a long-distance group cruise — with Hammerhead Bike Navigation ($85). Instead of the graphical display typical of most navigation devices, this one uses a series of colored LEDs as indicators, creating intuitive patterns that can be interpreted in your peripheral vision. As an added benefit, the device syncs wirelessly to your smartphone, letting you adjust the indicators, save and share routes, and even meet up with friends. And for those times when you're without a cellular signal, you can save routes to your phone and the onboard compass will still guide you along your way.
