Choosing a Mask Skirt Color.

Posted by DiveMaster in The Scuba Blog

clear skirt maskblack skirt maskTo choose a mask to fit properly you will first want to choose the proper mask style for your face size and special features, etc.  Take a look at the “How do I choose the right dive or snorkel mask?” in our Gear Questions area.

Now you are ready to choose the skirt style and color.  Most skirt “sealing surfaces” come in clear silicone.  These are most popular because they allow ambient light in for the wearer and ease the “claustrophobic” feeling often times associated with the underwater experience.

Black skirts have all the functionality of the clear versions but they do not allow ambient light in.  This may be an issue for some while many like it because the distractions of the ambient light are mitigated allow focused vision profile.  Another benefit you cannot see the sinuses draining.  Not cool if you are an Instructor or with someone you are trying to impress.

So, there you have it, choose your mask and when in doubt, ask and Instructor.

Choosing the Proper Snorkel?

Posted by DiveMaster in The Scuba Blog

dry snorkelSnorkels have changed allot but have always stayed in 3 basic categories.

  Dry, Splash Guard and Basic or traditional.  The dry snorkel gets its name from staying dry when you go under water, (providing the user keeps the mouthpiece in when doing so).


A dry top or splashguard style has the same attributes but not the dry feature that seals when taken under water.  The splashguard keeps water from freely entering the breathing tube when a wave may accidentally come over or the user mistakenly dips it under.

 Lastly a fixed position mouthpiece is best for snorkeling as the mouth piece will always be in you mouth and no jaw fatigue.  For Scuba the best is usually the corrugated version as when you are not using it, the mouthpiece flexes down and out of the way so you can make room for your regulator.

  The jaw fatigue factor is not as important as usually you don’t need to use it as often.

Proper Scuba Dive Weighting for Buoyancy Control

Posted by Instructor Bill in Scuba Diving Articles and Information

 weightsGuidelines for Proper Weighting.  We all know that most new divers tend to need a bit more weight than seasoned ones because Buoyancy Control takes several dives to master.  Common types of weights include pouchstyle with lead pellets (left) or solid lead style. 

I have over 3000 and still have a challenge every once in a while.  Here is the best rule of thumb for weighting that I have found:

FRESH Water:

Swimsuit or DiveSkin- Begin with 1 to 4 pounds / 0.5/2kg

Thin 3mm wetsuits or Shorty- 5% of your Body Weight

Medium Thickness 5mm suits- 10% of your Body Weight

Cold Water 7mm with hood/gloves- 10% of your Body Weight plus 3-5 pounds / 1.5/3kg

Neoprene Drysuit- 10% of your Body Weight plus 7-10 pounds / 3-5kg

Shell Style Dry Suits w/o under garment – 10% of your Body Weight plus 3-5 pounds / 1.5/3kg

Shell Style Dry Suits w/ heavy under garment – 10% of your Body Weight plus 7-14 pounds / 3-7kg

The undergarments vary quite a bit as they can realy add allot surface area to you thus increasing the amount of weight needed to stay neutrally buoyant.

Salt Water Diving (add to above calculations for Fresh Water)

100 to 125 lb (45-56kg) add 4 pounds (2kg)
126 to 155 lb (57-70kg)  add 5 pounds (2.3kg)
156 to 186 lb (71-85kg) add 6 pounds (3kg)
187 to 217 lb (86-99kg) add 7 pounds (3.2kg)

Always do a buoyancy check before beginning your dive and also factor in that if you are diving with an aluminum 80 tank you will need to add a little more to compesate for the tank toward the end of the dive.  If you are diving with a steel tank the same holds true except you will need less weight.  That is why it is so important to perform a neutral buoyancy check before beginning your dive.

Mask for Men with a Mustache

Posted by Instructor Bill in Scuba Gear Reviews and News

Question: My husband has a mustache which has made snorkeling nearly impossible due to water pouring into his mask.  Can you tell me if you sell as mask for men with a mustache and if so, what set would you  recommend? 

Answer: Normally folks with Mustache will go with a nose purge style mask as it will always leak but at least they can clear easily by exhaling via thier nose.  He may also want to put vaseline on it to help seal along with trimming below nose.  Check out the Mask Category and look for Masks with Nose Purges.
