Wild Country SRC with Belay Master
Here's what other sites are saying:
Wild Country wanted to create an auto-locking belay device that provided a more dynamic catch, and the Single Rope Controller (SRC) was born. With other auto-lock devices, the impact during a short fall causes the device to lock too quickly creating a static catch with a high impact force ouch. The Wild Country SRC is a time tested belay device that offers worry free protection.
