so the pole hose will stay on your reel of microbore and you simply plug it into your pole?
so i could just have one pole hose for multiple poles(say 50 feet length to accommodate xtreme 47).
it seems like a good idea but what about changing brushes and goosenecks during your working day?i use all gardiner poles,brushes and goosenecks.
this and the uni-valve could be the ultimate in water control and ease of use. 
It seems like a good idea until you examine it closer, forgetting the fact that all these disconnected poles will now drip
water into the van what is the point of this gadget unless you can only afford one pole and want to add and remove sections a little quicker.
Sean, I can answer that for you from my experience having gone to a diy'd tubeless system nearly 18 months ago for that very reason .
The end of the pole has a male rectus fitting, when you remove the hose, hold the pole vertically and any water in it will come out. It isn't a problem.
There is a point to using this gadget if the way you work gives you problems, mine is tangled pole hose and limited space in my pickup , and the fact I only use one pole through choice with sections added or removed ( not through any financial hardship ) for me it is an advantage, for you maybe not, the more choice and options that are out there, the better.
