The Trango Vergo belay device emphasizes ergonomics and human-device interaction to deliver exceptional performance.
Trango's new Vergo Belay Device brings the assisted braking device to whole new levels of safety and ergonomics for sport climbers and multi-pitch trad climbers. Unlike most assisted braking devices, the Vergo's safest way to use is also the smoothest. Clear visual and physical indicators make the Vergo easy to learn and even easier to use safely. Where most assisted braking devices require you to feed slack upwards, thereby causing shoulder strain, the Vergo promotes a natural process by feeding slack leftwards. It's nearly impossible to override the Vergo even if you're mishandling it, especially when compared to to standard assisted braking devices that require you to override the device for a millisecond (or longer) in order to dish out slack, lower climbers, or allow climbers to continue climbing after taking. The Vergo also works as a guide mode when you're belaying someone from anchors on a multi-pitch.
Trango has done it again with the Vergo Belay Device. The device feels comfortable in the hand and the belay method feels natural. By focusing on the end user, and exceeding industry certifications, safety gets a huge boost. Try it once and never go back.
