A matter of pressure?

Porpoise Bay 2014 005My friend and I are on a boat dive in British Columbia.  On the the first dive of the day, we are both diving 100 cubic feet (cf) tanks.  Mine is a high pressure steel rated at 3500 psi.  My buddies is a low pressure steel tank rated at 2400 psi, both 100cf.  At the end of the first dive, we both have 500 psi left.  Who has more air? Or are they equal?  Think about it.  Answer next week.  correct anser is the low pressure steel has more air.

Do I need Signaling Devices? ABSOLUTELY!

Fred1 picWhether you are diving in the Emerald Sea or somewhere tropical, currents are a fact of life.  And they will threaten that life if you are not prepared.

Before getting into an ocean environment you should be asking about Tides and Currents.  If you are not familiar with them, then ask your local dive shop or consult local Tide and Current tables.  There are even apps you can download to assist you.  Even if you are prepared, sometimes Mother Nature will throw you a curveball anyway.

In the event you find yourself caught in a current, establish positive buoyancy and assess your situation.  Often just swimming perpendicular to the current direction will be the simplest solution.  Depending upon depth and air reserve, sometimes taking a compass heading towards shore and dropping to bottom where current is often less severe and making your way out will work.  Other possibilities include ditching your weights allowing you move through the water easier, or/and signaling for assistance (more is covered in the Advance Open Water Class).images 

You should be carrying at least two signaling devices; a noise maker, which can be as simple as a whistle, or as loud as a Dive Alert, and a visual signaling aid, most often an inflatable orange or yellow safely sausage or signaling mirror.  Always carrying a dive light makes good sense too!

These items are just a must with boar diving.  In my years of experience, I have witnessed many divers get turned around and find themselves surfacing a good distance from the dive boat.  Having the ability to signal the boat to alert them to your presence is very comforting.

In the Argonaut Diving PADI Rescue class and the Advance Open Water Class, we practice deploying a safety sausage from depth and the surface, both valuable skills.  Click here for info on our next class.

Bottom line is, be conservative in your decisions when diving.  Dive smart, dive safe. Continue your dive training.  There is a whole new world out there beyond your Open Water class!  Let’s get wet!!

Why take the PADI Rescue Diver Class?

 If you do nothing else in diving, you owe it to yourself and your buddy to be Rescue Diver certified.  Here we kick it up to a whole new level.  We teach you how to recognize signs of distress in a diver or yourself. How to respond to an panicked diver or recovering an unconscious diver.  This is just the tip of the iceberg.  Passing this class will boost you confidence and give you tools you will use throughout your dive career!  rescue diver hat2Must be Adv certified to take this course and a current CPR/First Aid card.  Maroon Rescue Diver Hat with Argonaut logo included when passed. Cost is $250.00, includes book & video. Class usually meets either Wed or Thurs evening for academics at 6:00PM, then a pool session on Friday or Saturday, Open Water dives on Sat and/or Sun mornings. 

Boat (#scuba) Diving Etiquette

Fred1 picA lot of the great dive sites here in Puget Sound and up in British Columbia are only accessible by boat.  As a Diver, you need to be well versed in boat etiquette when schlepping your gear on board the dive charter.  Here are some helpful tips.

  1. Condense your gear.  Don’t bring bulky gear boxes on board. Pack it into a gear bag that takes less space when stored.  Space is a premium on board a dive boat, or any boat for that matter.  Be courteous and take only the space you need.  Don’t spread out into other dive stations, unless you know the boat is not full and there is room to do so!
  2. Be on time and listen to briefings.  Nothing is more frustrating than a group of divers being held up because one diver is late. Banditosidepicture In fact, many charters will disembark without you if you are not on time.  Departure times are often keyed into sensitive tides and estimated travel times to dive sites.  You being fifteen minutes late could impact the entire day of diving.  Also, know your set up times.  If you are one of those whom like to take their time setting up gear, start early.  Ask the Skipper or Divemaster, how far out it is to dive site.  Be ready to enter the water at the scheduled time.  And lastly listen to the briefings and the Boat skipper or crew. That means stop fiddling with your gear when they speak. Valuable information about emergency procedures and informative details of the dive sites are information you will not want to miss. 
  3. Have the proper training!  Many dive charters do not have limitations on certification levels for customers.  Here at Argonaut Diving, we require you to be minimum Advance Open Water certified to attend our chartered dive trips.  Mostly for your own safety and comfort.  Boat diving often deals with aspects of diving beyond the scope and skill of Open Water divers.  The primary being depth, followed closely by current.  Many NW dive sites are beyond OW Cert limits.  Know your entries.  Giant stride entry is the most prevalent in the Pacific Northwest.  Smaller vessels will often incorporate the roll back method.  Know how to do them.  Additional certifications above the PADI Boat Specialty class that are helpful are; PADI Enriched Air Diver, PADI Deep Diver, PADI Drift Diver, to name a few.  All are offered at Argonaut Diving.  Visit class page for more information and schedule.
  4. Carry in water signaling devices.  Every diver should carry a minimum of two signaling devices and be well versed in their usesausage.  One should be auditable, such as a whistle (minimum) or dive alert, which is connected to inflator hose (highly recommended).divealert  Alternately, the diver should carry a visible signaling device, such as a safety sausage, or hand held mirror.   Adding a small reel with 25 ft, of line comes in handy when doing a safety stop. Allowing you to deploy the safety sausage from depth, letting the boat crew know where you are, and as a signal to other boaters to practice caution as divers are below.  Lights for night are a must, of course.  An added note, for the dive alerts.  Don’t use them unless you need help!
  5. Be courteous and respectful of charter rules.  Stay out of areas that are off limits to divers, such as the wheel house (often called the bridge in larger vessels) and crews quarters.  Do not go into designated dry areas with your wet gear on.   Have situational awareness of the space you are using in relation to the next closest diver.  Be courteous.

Following these easy guidelines will almost assure you of great dive experiences.  Check out our Fun Dive and Events page for the next scheduled Boat Dive Charter.  space is always limited.  Continue your scuba education and challenge your horizons!  See ya in the water!  Dive Smart, Dive Safe!

Live to dive another day!

Fred1 picOne of the many skills we must have, as Scuba Divers, is the capacity to evaluate conditions, ourselves, of the dive site before plunging into the depths, whether it is on the beach or from a boat (charter).

If you are a dive leader, this responsibility becomes exponentially more important as your buddy and/or your fellow divers are counting on your expertise.    

Tides:   If you have done your homework and the site is tide sensitive, you have already checked the tides.  High slack is traditionally the best time to dive.  Timing your dive to when you hit slack is crucial in high tide sensitive areas.  If the tide has a rapid turn time, your time in the water will be limited.  Many who have dove Keystone Jetty on Whidbey Island, WA have firsthand experience of being caught in the water when the current suddenly shifts dramatically.  Even if you checked the tide tables before, evaluate when you get to the dive site.  Off shore storms/weather can affect the tides enough to shift slack times.  Look for evidence of current.  Drifting flotsam, maybe a buoy bentbuoybent over by current are just a few signs you can evaluate.

Weather:  Just as important as tides, weather also plays a key role for the dive.  Though we will spend the majority of the dive below the weather, we still have to pass through to get to the calm!  Heavy Surge, waves, wind, all are factors by themselves worthy of cancelling a dive.  If you are diving from a boat, the boat still has to navigate this weather to get to the site.  Motion sickness is not uncommon for some and can add to stress.  A surface swim in high seas becomes problematic at best whether it is to the beach or to the dive boat.  Wind will often accompany these heavy seas, making for a stronger surface current.  Large waves will preclude the use of your snorkel (should almost always dive with one) forcing you to use your Reg, assuming your air management allows this.  Exhaustion accompanied by an inability to help yourself is the result.

Divers training/conditioning:   Another factor to consider is diver training level and physical and psychological condition of yourself and your dive buddies.  Especially in cold water diving, where  the hardest part of the dive is often the getting into and out of the water.  Long walks or surface swims with heavy gear are not for the faint of heart.  Throw in some unruly surface conditions and cause for concern should be automatic.  A boat going through heavy seas adds sea sickness to the mix and now you have a recipe for an accident.  You may have noticed at Argonaut Diving, many of our local dive adventures require a minimum Advance Open Water training.  We recognize that many dive locations require a certain level of experience and/or training levels.  Make sure you are not leading your buddies into situations they have not been trained for by professionals.  An example of this would be leading an Open Water Diver down to 100 foot depth (OW certified to 60 ft).  Know your buddy’s cert level and experience level and whether it is suited for the dives site you are diving.

New Equipment:   Finally, taking new dive gear you are not familiar with, into an environment not conducive to trying that new gear out, is not a good idea. In the PADI Night Diver Specialty course you learn that trying new gear on a night dive is not a recommended.  Good advice.  Have new equipment?  Test it out in a more neutral environment and get use to it before tackling more challenging sites.

Ultimately, you have to be comfortable with the dive site.  If you find yourself fretting over the site for more than a few minutes, that in itself is a message that perhaps you are not ready for that particular environment.keystone jetty Feb 2013 001   Never feel pressure to not abort a dive for these reasons.  As responsible dive buddy’s we don’t argue with a buddy who is calling the dive.  We may discuss the issues, but ultimately we accept the call without dispute.  This becomes even more augmented when diving from a charter.  Just because a charter skipper has evaluated conditions as being acceptable for diving, does not mean your comfort levels are met.  You don’t like what you see, don’t dive.  Loss of charter fee is not worth your life.   Live to dive another day.  The good news is the water/ocean will be there tomorrow.  And if it is not, well then we all got bigger problems!

Dive smart, dive safe!
