Top 10 Best Emergency Signaling
If you're separated from the boat while scuba diving, getting attention can be a matter of life and death. We're constantly evaluating the latest emergency signaling devices to see how they perform against our existing favourites. Be seen and heard with our selection of the best visual and audible signaling gear.
Please keep the following in mind...
- Even small SMBs are more visible than a diver with no signaling device.
- By twilight, lights are far easier to spot than even the most visible SMBs are in daylight.
- Flashing lights aren’t particularly more noticeable than non-flashing, but a benefit of a flash or strobe mode is that it dramatically increases battery life.
Diving Near The Rip
A map of The Rip and surrounding features
"The Rip", also known as "The Heads", is the narrow waterway entrance connecting the Bass Strait to Port Phillip in southern Victoria, Australia. Because of large tidal flows through the relatively narrow channel from Port Phillip to the ocean, and a high rocky seabed, The Rip is a dangerous stretch of water and has claimed many ships and lives.
Geographically, The Rip is the roughly triangular area of water between the land points of Point Nepean on the Mornington Peninsula, Shortlands Bluff and Point Lonsdale on the Bellarine Peninsula, with these three forming The Heads.
There are many dive sites in the area of The Rip (The Heads), e.g. Port Phillip Heads Shipwreck Dives, and Melbourne divers need to understand the water movements and tidal flows to safely dive these sites.

The Rip & Tides Warning: Always keep an eye on sea conditions throughout any shore or boat dive within "The Rip" (aka "The Heads"). This is a dangerous stretch of water, where Bass Straight meets Port Phillip, which has claimed many ships and lives. Please read the warnings on the web page Diving Near The Rip before diving or snorkelling this site.
