SMACO S300 0.5L Mini Scuba Tank + Shoebox-1A Portable Air Compressor Kit

The maximum operating depth depends on the tank size:

0.5L–1L Tanks: Suitable for use up to 5 meters (16 feet). When used with a full-face mask, the maximum depth is 3 meters (10 feet).

2L Tanks: Suitable for use up to 10 meters (33 feet).

Breathing time varies depending on depth, activity level, and breathing rate. On average, 0.5L tanks provide approximately 6–10 minutes of air at shallow depths. 1L tanks offer around 15–20 minutes, while 2L tanks may last 30–35 minutes.

Always monitor your pressure gauge during use. If the pressure gauge shows less than 2 MPa, return to the surface and refill before diving again.

While certification is not required for shallow use, it is strongly recommended that all users receive proper instruction and certification from an accredited diving training agency. Improper use may lead to serious injury or death.

This product is designed for use in waters with temperatures above 10°C (50°F). Do not use in colder conditions.
