Liz Lim –
Is it also useful for canoeing purposes? Does the clip withstand strong water currents? Can I use it in extreme weather conditions?
Imran Hanafiah –
Thank you, Liz, for your question about using our Problue AC-27-8 Signal lock for canoeing. The compact design makes it easy to secure to a belt loop or a paddle clip, and the webbing and clip ensure it stays in place even in turbulent water. However, we do not recommend using it in extreme weather conditions like heavy storms or strong waves. The clip is designed to withstand normal water currents, but it’s always best to exercise caution when using any safety equipment in harsh environments.
