Dive Plan

Dive Plan is a decompression planning tool designed for technical divers, built on the Bühlmann ZHL-16C algorithm. It features dynamic gradient factor (GF) adjustment, multi-gas switching, dual-mode SAC management, and emergency bailout plan generation.

Pro-Grade Decompression Engine
Bühlmann ZHL-16C Algorithm:
Powered by the internationally recognized Swiss decompression model featuring a 16-compartment tissue structure, ensuring scientific accuracy and reliability.
Intelligent Auto Derating:
Built-in defensive logic automatically applies conservative adjustments for deep dives (>45m), cold water (<10°C), and high-altitude environments. This enhances safety margins without manual intervention.

Exclusive Dynamic Gradient Factors (GF)
Workload Adaptability:
An industry-leading dynamic GF system that auto-adjusts conservatism based on diver status (Resting, Light, Medium, Heavy).
Extreme Condition Lock:
Selecting "Heavy" workload forces the most conservative GF setting (20/65), specifically designed for strong currents or high-intensity operations, preventing human error.

Flexible Dive Profiling
Multi-Waypoint Support:
Supports complex multi-waypoint profiles, allowing individual configuration of depth, duration, and workload for each segment—ideal for cave, wreck, and technical deep dives.
Environmental Corrections:
Accepts altitude (0–3000m) and water temperature inputs. The algorithm automatically adjusts ambient pressure calculations for global dive sites.

Emergency Bailout Planning
Worst-Case Simulation:
Uniquely simulates catastrophic "deco gas loss" scenarios, automatically generating emergency decompression schedules using only bottom gas.
Survival Baseline Calculation:
Clearly defines the minimum required AIR volume and adjusted decompression stops, providing critical last-resort survival strategies for technical divers.

Multi Plans
Dual-Mode SAC Management:
Independently configure "Bottom SAC" and "Deco SAC" to accurately simulate real-world consumption differences between working and resting states.
Full-Spectrum Gas Support:
Comprehensive support for Air, Nitrox (EAN32/50), Oxygen, and Trimix. Custom gas blending is supported to meet deep diving and accelerated decompression needs.
1.5x Redundancy Advisory: Automatically calculates total gas consumption and provides redundancy recommendations to ensure flawless gas planning.

Enterprise-Ready & Usability
Offline Activation:
Supports device binding and offline license verification, enabling activation without internet connectivity—perfect for offshore operations or remote locations.
Smart Trial Protection:
Utilizes PlanID fingerprinting to prevent duplicate deduction; recalculating identical parameters does not consume trial credits, encouraging plan optimization.
One-Tap PDF Export:
Instantly generates comprehensive reports including schedules, gas consumption, and Bailout plans for team briefings, logging, and Buddy checks.
