Manfrotto 684B NEOTEC - Monopod With the same Neotec opening and closing mechanism as the 458B tripod, the 684B monopod is designed for support without sacrifice. It couldn't be easier or faster to set up - just pull the monopod leg downwards to open and automatically lock it in any position, with no screws, knobs or levers to tighten or loosen. Then to fold it back up again, pull the mechanism release trigger and push the leg closed. Its upside down construction also stops the worst of the mud you're standing in from ending up inside the monopod.
