A Chrono is a Must: FX Impact & Wildcat Regulators vs P15 Regulators

People have been telling me to take out my regulator and "Get a Huma Regulator". In this video I discuss the need for a Chrono and then I compare the FX Impact and Wildcat regulators against the P15s regulator. It is recommend that the highest and lowest pellet speed should not exceed exceed 30 feet per second. So how good are they.
