Detaching the display shoe of the i1Pro2

As those of you with an i1Pro2 may have noticed, the display shoe is hard to remove, unless you know the trick. So here's the recipe for right-handers:

 Hold the unit in your left hand so the open sole faces you, with the heel on the right.

 Now make a claw with two fingers and hook them under the shoe fastening, and push your thumb through the hole in the sole.  Exert the detaching force by pressing against the spectro with your thumb. The two pieces will then easily separate.
