Where to keep a surface whistle
A signalling device is useful only when reachable at the surface.
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
Attach it where you can reach it in gloves without interfering with inflator, alternative air or weight releases. Some whistles work poorly when wet; test its operation as the maker directs.
A practical approach
Include whistle location in the buddy check and practise signalling on the surface away from other boats.
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
