I am selling my 2010 Tachyon Micro XC camera. It is in great condition.....no scratches or dents and it works perfectly. This is a waterproof/tough camera that can be easily mounted to many things like bikes, helmets, and cars etc. You can also use velcro to attach it to various things like your pack strap or to a baseball cap, which is how I usually used it. The video quality is good, but I'd like to step-up to something with HD video quality.
You can see the details of it here along with some sample footage:
I'm selling it for 100 dollars, but I may be willing to part with it for a bit less.
