The Dive Otter

Pre Dive Planning

WARNING - I AM NOT A GUE TRAINED DIVER AND MOST CERTAINLY NOT A GUE INSTRUCTOR.
MY SUMMARY DESCRIPTION IS BASED ON SEEING THIS USED A COUPLE OF TIMES IN THE WILD.

One way I've seen done that I found highly effective was the GUE-EDGE method.

Goal

What are we trying to accomplish. Is this just a get wet dive? Is this a class? Are we wanting to swim around a wreck? Are we wanting to swim around half of the wreck and do a limited penetration of the wheel house? Are we wanting to take pictures?

Note the WE statements above. This discussion could certainly start with I want...but needs to eventually land on what we want.

Unified Team

Who's doing what? Who's leading? Are we going to switch leaders at some point? Who's carrying and launching the primary dSMB? Are we both carrying a dSMB? Am I working the reel and you are supporting or vice-versa? Do we use the same hand-signals, particularly for gas pressure? What is our procedure for a buddy seperation?

Everyone should have a "job".

Equipment

I'm diving HP100 doubles. You are diving Sidemount. I've got (2) dSMB's...if you have one do I need to carry 2? You're diving a long-hose...do I know how that works? Do we both need to carry a reel? Do we need a light? Do we want a light?

Do we have what we need to accomplish the goal and nothing more?

Exposure

What water temperature are we expecting? I'm in a drysuit and you're in a wetsuit. Our buoyancy characters might be different. Am I going to use drygloves or wet glovers with my drysuit?

Are we suited and booted appropriately for the expected conditions?

Decompression

Are we going to take a safety stop? At what depth? For how long?

There shouldn't be Additional Decompressional Obligations on a recreational dive, however we should at least agree on the Safety Stop.

Gas

How much? What kind? Does it match the Goal we set above?

Plan our dive. Dive our plan. Great time to do or validate the Rock Bottom Gas calculation.

Environmentals

Any boat traffic to worry about? Any dangerous animals? Fire corral? Is the wreck expected to be in poor condition? Is there likely to be a thermocline? Is the shore entry sand or rocks? Are there waves or swell? Are we using a downline?

Even an aggressive smallmouth bass at the shore entry can mess with your head. Discuss it - plan for it.
