BWARF or ABCDE
BWARF, or some type of model like it, is what virtually everyone was trained on and virtually nobody uses (unfortunately). It stands for:| BCD or Buoyancy | Does your buddy have their BCD setup correctly? |
| Weights | Does your buddy have their weights in? |
| Air | Do you/your buddy have their air on, do the regulators work is the PSI as expected? |
| Releases | Do you know how to operate your buddies BCD and drop weight 'releases' |
| Final OK | Are they ready to go? |
Some agencies teach ABCDE for both you and/or your buddy:
| Air | Do you/your buddy have their air on, do the regulators work is the PSI as expected? |
| BCD | Do you/your buddy have a working BCD inflate/deflate? Do you know how to use the various releases? |
| Computer | Do you/your buddy have their computer on and has it been configured correctly for the gas being dove? |
| Dive equipment | Do you/your buddy have all the equipment they need like fins and mask? |
| Enter the water | Go ahead and enter the water |
So how does it work in practice?
Here's a pretty good YouTube example from SSI, essentially it goes like this:Step 1 - Call the group together once everyone believes they are ready
Step 2 - Go to your buddy and make sure their tank is turned on
Step 3 - Buddy breathes off the primary and secondary regulators will you monitor the SPG pressure
Step 4 - You or the buddy check the inflate and deflate of their BCD
Step 5 - You verify your buddy's BCD releases are secured and you know how to operate them
Step 6 - Confirm weights are installed and inserted correctly and won't fall out
Step 7 - Signal OK
Step 8 - Switch roles and do it again for the other person
