Abstract
At each point of a Poisson point process of intensity in the hyperbolic place, center a ball of bounded random radius. Consider the probability that from a fixed point, there is some direction in which one can reach distance without hitting any ball. It is known \cite{BJST} that if is strictly smaller than a critical intensity then does not go to as . The main result in this note shows that in the case , the probability of reaching distance larger than decays essentially polynomial, while if , the decay is exponential. We also extend these results to various related models.
