We’ve been talking about the various kicking options that can be used for passing the treading water skill of the IADRS Watermanship test. This week we will discuss the upper body arm action commonly called sculling (or finning) of the arms. Similar to the leg motions, there are efficient and inefficient arm actions. We don’t want the dog paddle, slice and dice hands or dog paddling arms, but a smooth, steady almost figure-eight path with the hands when treading water. Go to the following link to access this week's Fitness Friday with more information!

Did you know getting bubblehead with a Polytex hood is preventable and a purge valve is not the best solution?
Diving a full face mask with an attached Polytex/latex hood can cause a “bubblehead” to form. Many divers will alleviate this by installing a small purge or hood vent to let out air. This is tantamount to drilling a hole in your tank and letting your air bleed away.
Chances are, you are diving a full face mask with a Polytex/latex hood because of contaminated water and this little valve and its flimsy diaphragm will not hold up to CW very well.
Bubblehead is caused by a poorly trimmed hood or an ill-fitting full face mask. To prevent:
• Trim your hood so you can’t see any hood inside your mask
• Adjust the full face mask for a better fit, or possibly get a different size skirt
Installing a hood vent is alleviating the symptom and not correcting the problem.
