My Pre-Dive Checklist

My Pre-Dive Checklist

Developed over 30 dives, my pre-dive checklist evolved naturally, refining the order of steps based on ease of use. It is laminated on a half-sheet (8x11, 14pt font) for durability and readability.

My Final Checklist

This checklist is minimal, designed for critical last-minute confirmations before entering the water. It prevents overlooked errors, particularly ensuring my tank valve is properly set—this check is done before stepping off a boat or shore entry.

My Packing List

Packing checklists prevent forgotten gear, a mistake too many divers make. I print one for every trip, checking off items as they are packed. I’m currently testing an iPad version—watch for a future blog post.

Checklists are a sign of thoughtful, responsible diving—not inexperience. They ensure thorough preparation, reduce errors, and make every dive safer and more enjoyable.
