As far as I can tell it's only pole section 1, the thinnest one, that has the male fitting on the end.
By adding extra pole sections all that is happening is the male fitting is getting further from the pole end bung.
I would have enough pole hose jointed to the normal minibore or microbore hose that means you can add extra pole lengths if you want.
So you would need a Stage 2 for each pole you wish to convert, two in your case, (male fiitings)
and one Stage 1 for the main hose reel. (female fitting).
I think he sells a Stage 1 &2 as a single item then add a stage 2 for your second pole.
