The ultimate in oval design to reduce water resistance.
The oval design, a unique feature of TUSA snorkels, has now been further improved in the pipe. It provides direction to water blown upward to insure a clear snorkel at all times while minimizing water resistance during snorkeling. The pipe interior, with its bellows section, has a new flush surface to further smooth the airflow.

 

New purge channel 2
The New Purge channel of the highly popular SP-130 was taken a step further for higher excellence by optimally positioning the purge valve for effortless cleaning. Since periphery on the valve always remains at the lowest point even when snorkeling upright at the water surface, water is easily cleared at allt imes. What's more, if there is water remaining in the snorkel it collects where it does not effect the airflow of the pipe at the farthest point from the mouth. As a result, is prevents gargling or sucking water when breathing.
