If anyone is interested, Amazon has the short tube for the GT now, with free prime shipping. They did have them for 12.99 a few days ago, but up to 15.99 now. But still, only having to wait 2 days instead of 3 or 4 weeks might be worth it to you.
edit, it seems the $3 off coupon is still active. It must disappear once you use it, which may be why I no longer see it.
It does look funny, and head heavy when holding the light. My thought is/was, it will fit better on the center console of my boat without falling over, but still pack the punch when trying to find the dock reflectors from 1/4 mile away.
