It is called the Auto-Magic filter because it is designed to work with auto-White Balance (WB) and auto-exposure (the original Magic filter requires manual WB). This makes it even easier to use that the original Magic, and means it works on all compacts, even those without manual WB.

I am very proud of the performance of this filter that really makes underwater photography point and shoot simple.
On Auto-WB it works between 3 and 10/12m (depending on the camera) although if you manually WB you can extend this to 18m.
We will be launching the filter in August, when I am back from Sardinia.
