Gemini disgorger is one of my favourite toys. (any similar t-bar will do the job). I think my first one came free with a magazine (the only useful free gift ever). I have a nasty habit of losing them

Think I am on my 3rd one now - I have covered it in reflective tape in an attempt to reduce the chances of losing it...
There's a knack to using it, but once you have it figured out then it suddenly becomes a doddle. I recall the days before I had my gemini - sessions of 20+ dogfish left hands in a right mess.
