Self-belay Devices For Solo Climbing

DO NOT CLIMB SOLO!
Nothing can make solo climbing safe.

These items are made for solo climbing, and should only be used by experts.

If you are reading this
then you do not have the necessary expertise.

They are all exceptionally well made and work well when used as intended, but there is no room for error when climbing alone, so the user must beware. Proper instruction and extensive experience are essential, but will not ensure your survival.

Do not even think about learning
anything about anything
from an internet web site.

I waited for two years for the Silent Partner to become available, and it was worth every minute. If you must climb alone and are looking for a top quality piece where money is no object, check this one out.

None of these devices will kill you, but they can let you kill yourself. Please:
