About this app

Create and review multilevel profiles with Bühlmann ZHL-16C decompression calculations, configurable gradient factors, gas planning, exposure control, and emergency scenarios. It is designed for trained technical divers who want to explore and document their dives clearly and flexibly.

Key Features:

• CCR, SCR, and Open Circuit modes
• Multilevel profiles with configurable descent and ascent rates
• Bühlmann ZHL-16C algorithm with adjustable Low and High Gradient Factors
• Selectable last stop at 3 m or 6 m
• Settings for freshwater, saltwater, and altitude diving
• Metric and imperial units
• Gas selection, MOD, PPO2, PPN2, PNE, and gas density checks
• Configurable warning and critical thresholds for oxygen exposure, narcosis, and gas density. • CNS and OTU exposure monitoring
• Planning of repetitive dives with residual tissue load, surface interval, and recovery of accumulated CNS and OTU.

• CCR rescue planning, SCR fail-safe, and open circuit emergency planning
• Configurable emergency criteria: maximum SurfGF, maximum time to surface, or maximum total gas required
• Gas loss scenarios, reserve rules, cylinder configuration, gas changes, and insufficient gas warnings
• Detailed summary, decompression plan, gas logistics, graphs, and exportable reports.

• English and Spanish interface

SCR planning includes active models with EAV, active fixed-flow models, and passive models, with specific cylinder management, setpoints, and gas consumption.

The application identifies potential problems such as hypoxic or hyperoxic exposure, high nitrogen partial pressure, high gas density, insufficient gas, depletion of emergency gases, exceeding reserves, and accumulated oxygen exposure.

Important: This application is only a planning and training aid. It is not a dive computer, does not monitor the actual dive, and should not be used as the sole basis for life support or decompression decisions. Always use proper training, accepted procedures, independent gas analysis, an appropriate dive computer, and conservative personal judgment.

What’s new

Fixed a bug in the calculation of failsafe gas consumption in SRC with EAV. Fixed a bug in the automatic gas calculation in OC and CCR which, in certain scenarios, recommended a smaller tank size than necessary
