Diving Tools
Task-led planning and blending tools for divers, instructors, and fill operators. Start with your intent: plan reserve, choose gas, or run a fill workflow.
Start by Task
Plan Reserve & Turn
Emergency reserve planning and turn strategy for the planned dive.
Choose & Check a Gas Mix
Pick a suitable mix for depth/PPO2 and verify depth limits before filling.
Blend / Fill a Cylinder
Run operational fill instructions with safety gates and readiness checks.
Set Personal Defaults
Save units, gear profiles, and preferences so calculators start in your context.
Match the Workflow to the Diver
These are the main user lanes the current app is optimized for.
Newer recreational / nitrox diver
Start in Gas Planning for reserve and turn checks, then use gas selection tools only when you need a target mix or MOD check.
Tech / cave diver
Use Gas Planning for reserve and gas-envelope work, then move into the Advanced Segmented Planner as a companion to your dedicated decompression planner.
Shop / fill operator
Start in Gas Blending for fill workflows, then use Best Mix, MOD, and cost helpers as supporting checks around the operational blend run.
Direct Entry
Use these when you already know the exact tool you want.
Browse by Stream
Use the hubs when you want routing help, not just a single calculator.
Safety Notice
Always verify calculations with certified equipment and follow proper diving procedures. These tools are designed to assist qualified divers and should not replace proper training and certification.
