Coloured screwgate carabiners can aid stance management by helping to easily identify attachment points; easing any confusion at a busy belay or in bad weather. Their use can benefit climbers of all abilities, and not just 'mountain professionals' such as guides and instructors looking after clients.
In the video, mountaineering instructor and trainee mountain guide, Rocio Siemens from Ibex Guides, demonstrates their practical use in a guiding scenario, climbing Flying Buttress (VD) on Dinas Cromlech in the Llanberis Pass. Each second is given their own distinct set of coloured screwgates with matching slings. DMM Shadow, Boa and Ultra O screwgate biners are available in red, green or blue, either individually or as a mixed-pack of three.
