ISC D4 Pro

Feedback gathered from highly qualified and experienced 'Pro' users highlighted a demand for a device which does not incorporate a panic-brake function. Enter the D4PRO! The D4PRO Descender is the same great Work/Rescue Descender, but without the panic brake.

This can be particularly useful on longer descents and in rescue/belay applications, where a broader 'sweet spot' is welcomed.
