The Bombimi CCR MOD app is built to make CCR gas planning faster, clearer, and less error-prone. It brings MOD checks, blend guidance, and pre-dive preparation into one place so you can plan with more confidence.

Web app - iPhone version - Android version

What it does

  • Calculates maximum operating depth (MOD) for CCR diluent mixes
  • Shows the limiting factor so you can see what is driving the depth limit
  • Supports trimix use with oxygen, helium and nitrogen considerations
  • Includes blending/top-up guidance when adjusting gases
  • Provides a pre-dive checklist to support consistent preparation

Why it helps

  • Reduces mental load when planning multiple gases
  • Helps avoid transcription and arithmetic mistakes
  • Keeps key planning checks in one place instead of across notes and calculators
  • Works well as a quick reference during setup and team planning

Typical use

  1. Enter your planned mix and planning limits.
  2. Review the calculated MOD and the reported limiting factor.
  3. Adjust blend assumptions if needed.
  4. Run through the checklist before finalising the dive plan.

⚠ WARNING: Technical diving is dangerous. This app is a planning aid, not a substitute for training, procedures, team checks, or independent verification of gas choices.
