Retired from commercial climbing years ago but am constantly looking for easier ways to get up and into a tree. Besides carabiners & slings, shot bags and grigri's---have found a device (at last) that makes getting around in a tree canopy much, much easier. Rope fetching device called a sidekick. Really helps in establishing multiple tie-in-points and is great at freeing up stuck monkey fists or throw bags. Light weight---telescopes to nine feet. Would like to hear from anyone else that can recommend a tool to make an old mans life easier?
