The 190XPROB, which replaces the best selling 190PROB has been redesigned to make the horizontal centre column feature even easier to use.  Simply extend the column to its highest position, release the lock and it will swing to its horizontal position with no need for column disassembly.  Both the lever leg locks and leg angle release system have been improved for simpler operation, whilst the tripod retains a convenient built in bubble level and foam hand grips.
