Diving Tips: How to Use a Safety Sausage
A safety sausage, also known as a Surface Marker Buoy (SMB), is one of the most important safety tools a diver can carry. However, simply owning one is not enough. Knowing how to use a safety sausage correctly while diving can make a critical difference, especially in current, poor visibility, or busy boat areas.
In this guide, we explain when to deploy a safety sausage, how to use it safely, and why regular practice matters.
Why Using a Safety Sausage Matters
At the surface, a diver is surprisingly difficult to see. Even in calm conditions, a head and tank sit low in the water. Add swell, current, or distance from the boat, and visibility drops quickly.
Using a safety sausage increases your visibility immediately. From a boat, a tall, brightly coloured SMB is far easier to spot than bubbles or a raised arm. This is why many dive operators strongly recommend — or require — divers to carry one.
When Should You Use a Safety Sausage?
Knowing when to use a safety sausage while diving is just as important as knowing how.
You should deploy your SMB:
– During a blue-water safety stop
– When surfacing away from the boat
– On drift dives with current
– In areas with boat traffic
– Whenever the boat is expected to come to you
Waiting until you are already stressed at the surface is a common mistake.
How to Use a Safety Sausage Safely
1. Stabilise Your Buoyancy
Before deployment, ensure you are neutrally buoyant. A rushed SMB deployment often leads to uncontrolled ascents or tangled lines.
2. Inflate Slowly
Add only a small amount of air at depth, either orally or with a low-pressure inflator. The air inside the safety sausage will expand as it rises. Overinflating too early can cause the SMB or line to pull upward forcefully.
3. Control the Line
Allow the safety sausage to rise smoothly while keeping light tension on your reel or spool. Make sure the line is clear of hoses, gauges, and your body.
4. Stay Visible at the Surface
Once you reach the surface, fully inflate the safety sausage and keep it upright. Height is key — the higher it stands above the water, the easier it is for the boat crew to see you.
Common Safety Sausage Mistakes
Even experienced divers make avoidable errors, including:
– Never practising SMB deployment
– Overinflating at depth
– Letting the line tangle around equipment
– Treating the safety sausage as optional gear
These mistakes are easily avoided with basic preparation and practice.
A safety sausage is not emergency equipment reserved for worst-case scenarios. It is standard diving safety gear designed to be used regularly.
Practising how to use a safety sausage in calm conditions will help ensure that, when conditions are less than ideal, you can deploy it confidently and correctly.
