What makes Surface Marker WDS so special?
..The Webbing Deployment System - it makes it a breeze to deploy your Surface Marker Buoy from your Safety Stop.
- No reels or spools needed
- No string to get tangled
- Streamlined & Compact System
What happens if I am on the surface and do not have enough air in my tank to inflate the safety sausage?
Bunch the opening of the buoy together as you would do if blowing into a paper bag, and blow into the buoy to fully inflate. The bottom end can also be twisted shut to ensure that the air stays trapped inside if you need to wave the surface marker for more attention.
With the Surface Marker Tek Buoy this is made easier with the Self – Sealing / One-Way Baffle that does not allow any air to escape once it passes through the opening, thereby ensuring that the buoy remains inflated until vented through the OP Valve (dump valve).
What is the advantage of using both yellow and orange on the Signal Tube / Safety Sausage?
Both yellow and orange are the most visible colours on the surface. You will find that in varying light conditions one colour will stand out more than the other ensuring that you are always visible. The orange is more visible in bright sunlight while the yellow stands out more as the light fades or rainy days.
Why doesn’t the Diver Signal Tube with WDS have a self-sealing opening?
The Surface Marker WDS and Deluxe units are not self-sealing; won’t the air spill out from the opening when I deploy them from my safety stop?
No not when using the WDS, the buoy and Webbing Deployment System (WDS) have been designed in such a manner that:
When the buoy is inflated from 5-6m (15-18ft) and released, the weight of the brass snap hook (on the WDS) and the weight of the stainless steel ring on the buoy will always keep the open end of the buoy far enough underwater to ensure that air does not spill from the unit and deflate.
On the surface, once the WDS has been secured with the Bungy, you can let go of the whole unit without worrying about the unit deflating; since there is enough weight on the whole WDS to ensure that the opening of the buoy is always submerged even in a swell.
Therefore there is no need for an OPV (Over Pressure Valve). By eliminating the need for and OPV the unit is much more compact and easier stow as well as being able to fully deflate the unit in a matter of seconds for stowage.
Note: The Surface Marker WDS Buoy was designed for recreational divers doing safety stops and was not designed for technical decompression divers.
I have a plastic / PVC signal tube, is this good enough?
Plastic / PVC safety sausages are not an option; they can burst at the most critical times, they stick together if not used regularly, they are very easily destroyed by UV exposure. These items belong in the toy department, would you use a BCD made of the same material?
When should I use my safety sausage?
As a recreational diver the best time to inflate your Surface Marker Buoy is at your Safety Stop. For the following reasons:
- Alert the boat crew of your current location and intent to surface.
- Allow the boat to track you if drifting in a current.
- Make other boat traffic aware of your presence.
- Use as a reference during your safety stop.
In a 2 knot current you can drift up to 400m (1/4 mile) just during a 5 minute Safety Stop. It makes good sense to deploy you SMB during your Safety Stop.
I am worried about the Webbing Deployment System and particularly about placing the stainless steel ring over my thumb. What happens if I deploy the unit to deep or the system gets snagged?
The stainless steel ring on the WDS is quite large and highly polished, and will easily slip off your thumb without any problems in case the unit gets snagged, all you have to do is open your thumb (thumbs up and its away).You are not tying yourself to anything you are simply slipping a over sized stainless steel ring (internal diameter 3cm or 1.18") over your thumb which is only holding the unit while it deploys. Basically in the same manner as you would hold a small handle with your thumb - open you thumb release the handle.
Should you deploy the unit deeper that the allowed depth for the WDS (5.5m / 18ft) you will fell a gentle upwards tug on the lanyard allowing you to release it. The webbing actually absorbs most of the shock due to its width, length and inherent elasticity.
