In the unlikely event that you’re at the surface and need to get the attention of someone on shore or on a boat, you’ll be glad you have a surface signaling device. Signaling devices are important safety equipment that help scuba divers be seen and heard if they need assistance. The recommendation is to always carry at least two devices – one audible and one visual. Visit your PADI Dive Center or Resort to get advice about surface signaling devices.
The great thing about choosing a surface signaling device is that you can’t have too many for safety. Considering that you should have at least two – one audible and one visual – you may start with a whistle and inflatable signal tube or DSMB (if required in your area). If you’ll dive in more remote destinations, add a signal mirror and air horn to your kit. Ask the dive professional at your local PADI dive shop about which devices divers use in the local area.
