Probably because he's unaware of the older non-rotary Jobo tanks, the centre columns are slightly narrower than the Paterson but I use mine frequently with Paterson reels. Of course these tanks will take the Jobo 5"x4" reels anyway. I have 4 2000 series Jobo tanks and if I needed greater capacity I'd try a MOD 54.
