Tracer tests in practice

Almost every caver has heard already from tracer tests or helped out himself at such a test. But: does everyone know what to pay attention? What are the (also legal) regulations? Which colorants are available? These and many other questions will be answered in this workshop.At the same time, it serves as a discussion platform about sense and nonsense of tracer tests, what one can see without tracers and what one doesn’t see even with tracers. This workshop will be held by Martin Otz, who has decades of experience in this topic.
No prior knowledge on the subject is necessary.
