TUSA SP-170 Platina Hyperdry II Scuba Diving Snorkel - Semi-Dry

In this review of the TUSA SP-170 Platina Hyperdry II snorkel the bottom line is simple: this is a comfortable, technically smart semi-dry snorkel for swimmers, freedivers and recreational scuba users who want easier clearing and reduced water intrusion. The review highlights the patented Hyperdry system as the single biggest reason to buy, since it expels water through a separate escape pipe and keeps the main tube drier than a basic open snorkel while remaining compact and comfortable enough for longer surface swims.

Key Features

• Hyperdry system: The patented escape pipe and three current-rectifying plates help push water out of the main tube so breathing stays clearer near the surface.
• High flow purge valve: An angled purge valve moves water and bubbles away from the face and allows quick, low-effort clearing when water enters the lower tube.
• Ergonomic mouthpiece: The ortho-consciously designed mouthpiece reduces jaw fatigue and stays comfortable for extended snorkeling or freediving sessions.
• Smooth corrugated lower tube: A smooth internal bore in the corrugated section improves airflow and creates a more natural, unobstructed breath.
• Swivel adapter snorkel keeper: The included swivel adapter offers an easy, secure attachment to masks and keeps the snorkel positioned correctly during dives.

Who It's For

This snorkel suits recreational snorkelers who want better dryness than a basic tube and freedivers who prize easy clearing and a compact profile. The smaller mouthpiece also makes it a good fit for women and younger adults who find many mouthpieces too bulky.

It is less suitable for users who need a fully dry snorkel in heavy chop or for those who require a very large mouthpiece for extended regulator-based scuba use; this model is designed as a semi-dry snorkel optimized for surface breathing and quick transition to a scuba regulator.

Pros & Cons

Pros

• Effective semi-dry performance from the Hyperdry system that reduces water entry into the main breathing tube.
• Easy clearing thanks to the angled high-flow purge valve and smooth internal bore.
• Comfortable, ortho-consciously designed mouthpiece that reduces jaw strain and suits smaller mouths.
• Flexible lower tube and swivel adapter make mask attachment and positioning simple.

Cons

• Not a fully dry snorkel for all conditions; some users may still notice occasional water ingress in rough surf.
