Introducing the GTR Cap from @gordoscientific and @highlyeducatedti. The GTR Cap is a dual-channel carb cap that combines the functionality of a Gordo riptide cap and a traditional straight bubble cap. The two channels have been separated to create the dual functionality which can be operated independently or in coordination with one another. The cap features two openings, one on the handle and one on the bubble. When in use; a finger placed over the opening of the handle closes the center channel activating the riptide channel. A finger placed over the opening on the side of the bubble, will activate the center channel and make the cap perform like a traditional bubble cap. This puts more control in the operators fingertips and gives you the option to use a larger spread air stream that a riptide cap offers, the more direct straight stream that a bubble cap offers, or both at the same time. Depending on whatever your puddle calls for at the moment you can now switch the function, without switching caps.
