The D4 Work/Rescue Descender has proven to be a popular Descender amongst Rope Access & Rescue users, all over the world. Many users value the extra peace of mind of having a panic-brake function.
The 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.
