After buying and using a new Manfrotto 523PROi pan handle for a couple of years, I discovered there are 2 versions of it. Mine has a ‘removable’ coiled LANC cable from the handle, the other one has what looks like a ‘fixed’ coiled LANC cable.

Why are there 2 versions, if mine is the newer version what updates did Manfrotto include, just the removable coiled cable from the handle?
Cheers.
