Depth Specific Engineering

Our bags are rated for shallow (30m), mid-depth (100m), and deep-sea (300m+) operations.

FAQ

1. How do I inflate the bag underwater?

Via scuba regulator, surface-supplied air, or low-pressure compressor.

2. What’s the maximum lift speed?

Recommended ≤10m/min to avoid uncontrolled ascent.

3. How do I attach it to a load?

Use integrated D-rings with slings/chains, ensuring balanced rigging.

4. Can multiple bags be used together?

Yes, synchronized lifting with evenly distributed bags is common for heavy loads.

5. How do I deflate the bag?

Open dump valves or invert the bag to release air.
