Features:

• Hyperdry system with three current rectifying plates.
• New pre-angled purge valve to eliminate gurgling of water by breathing and let air bubbles pass by the side of the face.
• Ortho-consciously designed mouthpiece for ultimate comfort.
• Detachable two-sectional swivel adapter to minimize the pulling feeling.
• Three-dimensional pipe curve for the ideal angle for snorkeling.

Description:

Three-dimensional pipe curve is the result of years of snorkel design and repeated model changes. Using the average posture when swimming on the surface as the basis, it maintains the ideal angle for effective breathing. To insure that the pipe top is close to the top of the head, it is curved along the head section and has an incline at the back. This creates a greater feeling of unity between the snorkel and head to further reduce water resistance.

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.

New mouthpiece
The new mouthpiece, developed on the basis of ergonomic engineering, further enhances the comfort of bite, fit, and stability. Even with a light bite, a high level of stability is achieved, so there is no fatigue from long periods of usage.

New two-sectional swivel adapter (PAT.P) enhances comfort & performance.
The SP-170 features a newly developed snorkel adapter that integrates a swivel mechanism to the pipe clip and strap attachment. The new adapter includes the following two features:
1. This mechanism allows the snorkel to swivel to the optimum angle to reduce tension
and stress for enhanced comfort and performance as compared to earlier models.
2. Adjustments are made by sliding the adapter's position forward or back --a forward or rearward position may be selected. For example, depending on the size of the head, if the adapter is too close to the mouth, the corrugated tube may become excessively bent reducing airflow. By sliding the new adapter backward, stress on the corrugated tube is eliminated and the bite on the mouthpiece becomes more natural. Also, the top of the pipe which extends above the surface of the water is placed in an optimal position. In addition, by sliding the pipe clip forward and off the strap attachment, the snorkel can be easily detached from the mask.
