Lift Bags


Many divers carry lift bags to raise objects to the surface. Typically, divers secure the object to the lift bag along with a line attached to a reel. The lift bag is filled with air and sent to the surface from the bottom. As the lift bag rises to the surface, the expanding excess air can escape through the opening on the bottom. This keeps the lift bag from splitting a seam and dropping the load to the bottom. The reel and line serve as a means of keeping the bag and its load from drifting too far away. Some lift bags are also equipped with a dump valve which allows the diver to ascend with the load and actually trim buoyancy to remain near neutral throughout the ascent. This keeps delicate loads from being left on the surface alone and subjected to wave action.

Divers have also used the lift bag as a means of signaling their location if an ascent is performed away from the anchor line or during drifting deco stops. The lift bag on the surface allows the boat crew to track the diver's position in the water. However, there are problems with using lift bags as marking devices. Without a load on the lift bag, upon reaching the surface, it often flops over and deflates. If this happens, the bag may actually begin to sink and be rendered useless. Also, the shape of a lift bag is not designed for optimal visibility.

You can get it to the surface with these premium quality lift bags from The Scuba Doctor dive shop, now available at everyday low prices.



Sharing at The Scuba Doctor

Some of the pages on The Scuba Doctor site now contain a set of links to external social websites. This enables you to share The Scuba Doctor pages that you find interesting with your friends and contacts on those external sites.

Whilst The Scuba Doctor does not link to a site in return for money, goods or services, we are part of the wider web, and many of our users also use social networks and bookmarking services. We want you to be able to share and comment on the content we produce, if you wish to, and these links make that easier.

How does sharing work?

All of these sites are free to use and require you to register with them. Once you have registered you can begin sharing links.

You will not need an account with The Scuba Doctor to do this. When you click on a site's logo you will be directed away from The Scuba Doctor website to the social site. The Scuba Doctor will not ask you for any personal information during this process.

Please note, when you click on one of these links and navigate to an external site such as Facebook or Twitter, you will be subject to the terms of use and privacy policy of that website. Also note, clicking on these links may result in a cookie being set in your browser by the website with which you have chosen to share a The Scuba Doctor page.

What happens when I use the links on your pages to share items?

Sharing an article is a simple process. When you navigate to any of the available external sites — Facebook, Twitter, Instagram, Pinterest, Delicious, Digg, Reddit or StumbleUpon — a pop-up will appear that enables you to sign in to that site (if you are not already signed in), and then share the link.

Which services do you link to?

Currently, we provide prominent buttons that will help you use four sites — Facebook, Twitter, Instagram and Pinterest — as well as a 'share menu' that provides access to others like Delicious, Digg, StumbleUpon and Reddit.

How did you decide which services to link to?

We have chosen the most relevant social sites for our users by assessing the volume of referrals from those sites to The Scuba Doctor website, their technical compatibility, and the number of users they have overall. All of the services chosen are currently free at the point of access for users. We monitor the range of social sites on the internet and regularly review our choice.

Why are Facebook and Twitter more prominent than the other networks?

We are reflecting the preferences of users in Australia. Currently Facebook is the largest social network and Twitter, although having a smaller audience than Facebook, is growing faster than any other social site. Both also offer the technical capability to enable sharing activities.
