I have found that as long as the item was not-bulky (re: smaller than a reefmaster camera) then access to the Ranger's pockets was realtively easy.
But like the others have said, you must access the pockets by feel since your view is obstructed by you're gear.
However, I have found this to be the case with almost all the vest and back inflate BC's I have used.
Other than this, I have found the Ranger to be a very capable BC that will take you far in your diving career. But I will direct you to the BackPlate/Wing's BC's if you see yourself ever doing diving that involved doubles, stage bottles, or other tekkie things.
