Quick Verdict

Is the SMACO K2 mask set worth buying?

This is the cheapest way into SMACO's mini scuba range, at $199.99 down from $299.99, with 4.87 stars from 23 reviews on the page. You get a full-face snorkel mask with a camera mount plus an S300 or S300Pro tank. You must stay within 3 meters (10ft) and watch the pressure gauge, so think of it as a shallow-water play kit.

Great forCasual snorkelers who want to add a few minutes of breathing underwater and film it.

Reconsider ifYou want deeper or longer dives. Mini scuba is not a substitute for dive training. Read SMACO's user manual and safety guidelines, never dive alone, and get medical clearance if you are over 60.

Overview

A full-face mask with tank

The kit is the K2 full-face mask (model M8068) with SMACO's S300 (0.5L) or S300Pro (0.7L) tank. It comes with a safety leash and carrying bag, and the tank is CE, TUV and DOT certified.

Key Features

What makes it stand out

01 · Mask

Full-face with camera mount

A built-in action-camera mount lets you record hands-free, and the full-face design lets you breathe through the nose and mouth when snorkeling.

02 · Tank options

S300 or S300Pro

S300: 0.5L, about 35 breaths at 5m, 1.1kg. S300Pro: 0.7L, about 52 breaths, 1.54kg. Both are 200 bar (3000 psi).

03 · Depth

Stay within 3 meters

SMACO says to always monitor the gauge and not go beyond 3 meters (10ft). That is shallow, so it suits pools, calm shores and boat snorkeling.

04 · Portability

Under 4 lbs with a bag

The kit weighs under 4 lbs, includes a safety leash and carrying bag, and comes with 30-day returns and a one-year warranty.
