### 1. Deco for Divers: A Diver's Guide to Decompression Theory and Physiology (2nd Edition)

**Author:** Mark Powell

Mark Powell's explanation of decompression theory for divers who want more than the tables. Covers gas uptake, Haldane and bubble models, gradient factors, deep stops, nitrox and mixed gas, and what dive computers actually calculate. It is the usual recommendation for understanding what a dive computer is doing.

**Difficulty:** Intermediate | **Language:** English | **Price:** Paid

**Tags:** decompression-theory, dive-physiology, gradient-factors, dive-computers, technical-diving

### 2. Scuba Diving (5th Edition)

**Author:** Dennis Graver

An agency-neutral beginner textbook by former PADI and NAUI training director Dennis Graver. Covers diving science and gas laws, physical adjustments underwater, equipment, aquatic environments, core skills, dive planning and further diving opportunities. A good beginner book to read alongside an in-person Open Water course.

### 4. U.S. Navy Diving Manual (Revision 7, Change A)

**Author:** Naval Sea Systems Command (NAVSEA)

This is the source that recreational training material draws its gas laws, physiology and decompression theory from. The Navy's official five-volume diving manual, free to download as PDF or ePub from NAVSEA. Volume 1 covers diving physics, physiology and policy; later volumes cover air decompression tables, mixed gas, rebreathers and diving medicine.

**Difficulty:** Advanced | **Language:** English | **Price:** Free
