More than numbers.
A picture you can explore.

See how a profile, its gases, and its decompression model connect. The details stay close to the bigger picture.

01 / VISUALIZE

Follow the whole profile.

Gas switches, decompression stops, and tissue saturation — brought together in a visual workspace.

02 / UNDERSTAND

A familiar model. Room to explore.

Bühlmann ZH-L16C with customizable GF Low and GF High.

03 / EXPLORE

Two ways to see the theory.

Open circuit multi-gas profiles and closed circuit rebreather support, including bailout planning concepts.

From inputs to insight

Explore. Adjust.
See what changes.

A visual way to study the relationships behind decompression.

  1. Shape a profile.

    Explore depth, time, gas mixes, and ascent and descent rates.

  2. Look beneath the curve.

    Adjust gradient factors and explore open circuit, CCR, and bailout profiles.

  3. Read the details.

    Follow decompression stops, tissue loading, and time to surface in one place.

Beyond the profile

Keep the details
in the picture.

Explore equivalent narcotic depth, gas density, and time to surface. DiveHub also supports wireless Nitrox analyzers.
