Introduction

As a scuba diver, planning a safe and efficient dive is crucial to ensure a successful and enjoyable experience. The APD Projection DivePlanner is a powerful tool that helps divers plan their dives with precision, taking into account various factors such as depth, time, and gas composition. In this article, we will delve into the features and capabilities of the APD Projection DivePlanner, exploring its benefits and how it can be used to plan safe and efficient dives.

Main Features

The APD Projection DivePlanner is a comprehensive tool that offers a range of features to help divers plan their dives. Some of its key features include:

Gradient Factor Adjustable Bühlmann C Algorithm: The APD Projection DivePlanner uses the Bühlmann C algorithm, which is a widely accepted and reliable method for calculating decompression. The algorithm can be adjusted to accommodate different gradient factors, allowing divers to customize their dive plans to suit their needs.
Multiple Gasses: The APD Projection DivePlanner allows divers to plan dives using multiple gases, including Nitrox, Trimix, and Heliox. This feature is particularly useful for technical divers who require specific gas mixes for their dives.
Plan a Single Dive or Series of Dives: The APD Projection DivePlanner enables divers to plan single dives or series of dives, taking into account the surface interval desaturation according to Bühlmann or Hahn. This feature is useful for divers who plan to make multiple dives in a single day.
Plan Altitude Dives: The APD Projection DivePlanner allows divers to plan dives at altitude, taking into account the effects of altitude on gas composition and decompression.
Desaturation Between Dives: The APD Projection DivePlanner can calculate the desaturation between dives using either Bühlmann's algorithm or Hahn's desaturation rates. This feature is useful for divers who plan to make multiple dives in a single day.
Powerful Table Generator: The APD Projection DivePlanner features a powerful table generator that can calculate multiple dive profiles for a range of depths and dive times. The generator can produce tables in depth ascending or depth descending format, making it easy to plan and execute dives.
Isobaric Counter Diffusion Warnings: The APD Projection DivePlanner includes isobaric counter diffusion warnings, which alert divers to potential risks associated with gas diffusion.
Low and High O2 Warnings: The APD Projection DivePlanner includes low and high O2 warnings, which alert divers to potential risks associated with oxygen toxicity.
CNS and OTU Warnings: The APD Projection DivePlanner includes CNS and OTU warnings, which alert divers to potential risks associated with central nervous system and oxygen toxicity.
OC Gas Volume Calculations: The APD Projection DivePlanner includes OC gas volume calculations, which enable divers to plan and execute open circuit dives with precision.
