Light choices for a night dive
Brightness alone does not make an underwater torch useful.
Safety and training
General field notes, not a dive plan. Stay within your training, follow local site rules and the operator’s briefing.
Field observation
Consider beam width, burn time, charging and a backup suited to the planned dive. A narrow beam helps point at details; a wide one can improve orientation but may disturb your buddy or animals.
A practical approach
Test the light and switch before entry, avoid shining into faces and agree a lost-light response with the team.
Dive-day checklist
Before you go
- Check local conditions and access rules
- Agree limits and the exit with your buddy
- Stop or change the plan if conditions differ
