If you're looking for a lightweight Carbon Fiber Monopod, here's a great deal. This Rokinon Carbon Fiber 5 section monopod is selling for just $39 + FREE SHIPPING (USA domestic). If you want to throw a monopod into your airline carry on bag, 21" is about the max length you should be looking for. This Rokinon is perfect since it can collapse down to just 18", yet extends to a max height of 65" inches. I've looked around for other deals, but could not find this type of minimum-maximum range in another Carbon Fiber Monopod at this price. It's worth taking a look at. Includes: carrying case for easy hands free transporting. Check it out via eBay (Click here).
