SP-170 
- Hyperdry System with three current rectifying plates
- Pre-angled purge valve eliminates gurgling of water by breathing and allowing air bubbles to pass by the side of the face
- Ortho-consciously designed mouthpiece for ultimate comfort
- Detachable two-section swivel adapter minimizes the pulling feeling
- Three-dimensional pipe curve gives the ideal angle for snorkeling
The sensation of residual water (gurgling) while snorkeling is eliminated. This revolutionary snorkel uses a new mouthpiece, designed with the aid of ergonomic engineering.
SP-170QBThis design features a black silicone flexible joint and mouthpiece. The pipe is available in Black (BK) and Black/Red (BK/R).
| In the European market, snorkel top of SP-130(QB) is EN1972 standard version. |  |
Features of SP-170
The ultimate in oval design to reduce water resistance.
The oval design, a feature unique to TUSA snorkels, has now been further improved in the pipe. It provides direction to water blown upward to insure a clear snorkel while minimizing water resistance. The pipe interior, with its bellows section, has a new flush surface to further smooth the airflow.
New two-sectional swivel adapter enhances comfort and performance.

The SP-130 features a newly developed snorkel adapter that integrates a swivel mechanism to the pipe clip and strap attachment (Photos 1 & 2). 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 (Photo 2) as compared to earlier models (Photo 3).
2. Adjustments are made by sliding the adapter's position forward or backward, and either a forward or rearward position may be selected (Photo 4). For example, if the adapter is too close to your mouth, the corrugated tube may become excessively bent reducing airflow. By sliding the new adapter backward (Photo 2), stress on the corrugated tube is eliminated and the bite on the mouthpiece becomes more natural. This also places the top of the pipe which extends above the surface of the water in an optimal position. In addition, the snorkel can be easily detached from the mask by sliding the pipe clip forward and off the strap attachment.
New purge channel
Since the purge valve is at an angle to the body, even if water remains in the chamber after clearing the snorkel it will not affect the flow of air in the pipe (away from the mouth). Therefore, there is no gurgling of water caused by breathing, and water does not return to the mouth. In addition, air bubbles that come from the valve pass by the side of the face without obstructing the field of view.
New mouthpiece
The new ergonomically engineered mouthpiece 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.
