In stock now. The new D5Y was exclusively designed for Yates by ISC  it is a double stop device. Wear parts approach the point of indestructibility. Handle is made of aluminum (as opposed to plastic), and is extremely durable. 

The D5Y Descender allows for controlled descent at different speeds. A user can move slowly, or get going much quicker than they can on a Petzl ID. However, it still has the anti-panic in case a user pulls the handle too hard. Handle spins all the way around, and gives audible clicks as it resets. NEW handle position is approx. 25 degrees back from the origional prototype position allowing for a more ergonomic position for the user.

Device is suitable for a two-person rescue without extra friction (i.e. using an extra carabiner with a redirect).

The D5Y Descent Device opens with a push button. Button is easy to open, even with gloves, but is difficult to open under load, decreasing risk of accidental opening. Button audibly clicks when device is closed.

The D5Y is approved for ANSI Z359.4-2013, and NFPA "T". This descent device works great for rope access work, progress capture in haul systems, rescue, tower climbing, and lots more. It's one of the first descent devices on the market to have ANSI stamped on it!
