Working as dive professional you'll need to know you're way around a boat and using the proper terminology will help with navigating your way around vessels both at the surface and underwater.

The front is the Bow

The rear is the Stern

The right side whilst facing the bow is Starboard Side

The left side whilst facing the bow is Port Side.

PADI's maximum rate of ascent is 18m/min. It must be stressed that this is their maximum and they advocate the S.A.F.E protocol - Safely Ascend From Every Dive, and it's practical to follow the ascent rate meter of your personal dive computer which is set more conservatively.

Quiet often called a collapsed lung pneumothorax translates to air in the chest cavity. There are various types but first aid protocols are the same. 

Refer to your doctor if you have a history of pneumothorax as it may be a contraindication to partaking in SCUBA programs.

When choosing a BCD always consider not only your own weight that must be kept positively buoyant at the surface but also the equipment that you may be taking diving; weight system, cylinder material types and sizes, camera equipment etc.

If in doubt choose the maximum lift you can get, especially as a dive professional. Book Now for you dive professional development programs and Ignite Your Life today!

The constants for physics questions are written on every PADI exam sheet. Every metre of fresh water exerts 0.097ATM of pressure. So this equation is 16m X 0.097 ATM = 1.55.

Since the question asks for gauge pressure; meaning a zero sum at the surface therefore not including the atmospheric pressure of the air, there is no need to add 1ATM which is where people often go wrong.
