This skin - diving book is a great resource for both beginners and experienced divers. To use it, simply flip through the pages to find useful tips, techniques, and information about skin diving. When handling the book, be careful not to spill any liquids on it as it has some soiling already. To maintain it, store it in a dry and cool place. Keep it away from direct sunlight to prevent further damage to the cover and pages. If you want to mark important pages, use a bookmark instead of folding the corners.
