Woodman Point Diver's Dream Club Dive

Wednesday 17 May 2023

Tonight’s dive at Woodman Point was a diver’s dream. The water was glass off, and not even a hint of a breeze. The water was crystal clear, visibility was as far as your torch would allow. What an absolutely beautiful dive this was.

We saw cuttlefish, octopus, 2 huge balls of juvenile striped catfish, a couple of crays, a couple of juvenile snook which was a big surprise, and at the end of the Groyne we were delighted by every single size and colour of seahorse you could imagine. The water temperature is dropping for sure, 4 of us were in dry suits and the rest in wetties … they were the ones who came out looking like Smurfs!

If you were ever considering investing in a dry suit, now is the time. The ocean is waiting… see you soon at another Perth Scuba Manta Club dive!

Blackwall Reach Club Night Dive

Wednesday 10 May 2023

What an awesome Wednesday night out for our Manta Club members weekly night dive. With dodgy weather forecasts in place along the coast we ventured back to the river and my favourite spot, Blackwall Reach.

Water was flat and despite a bit of a surface current it was a great dive. Visibility was great and plenty an underwater critter to see.

Tonight we followed a new underwater trail line put down by local diver Christopher Benzie Dodd. You now have the option to either surface swim, as we have always done, to the marker buoy then descend onto the barge or to follow the new line that starts not far from the jetty underwater direct to the barge. Either way you are in for a treat.

As the seasons change we will spend more time back in the river. It is an awesome place to dive, especially at night in winter.

Thanks to all the divers that braved the night and made it a lot of fun.

Instructor Examination Weekend

6 - 7 May 2023

Perth Scuba's Instructor Development Team are pleased to announce the Success of seven newly certified PADI Open Water Scuba Instructors.

After a weekend of theory examinations, classroom presentations, confined and open water presentations the reward was to become PADIs newest Open Water Dive Instructors.

In trying, cold conditions, the weekend started with Theory Examinations and Knowledge Development stress levels were a little higher than normal but with an average pass mark of 96% the candidates proved their Dive theory knowledge.

Confined Water presentations are built around the technical aspects of Confined Water presentations but again with confidence from previous results in the classroom the candidates surpassed all expectations.

Rockingham Wreck Trail presents another challenge, currents, wind and chilly water temperatures were conditions set for the candidates open water presentations and rescue diver assessment.

Professional at all times the candidates did not only manage conditions but excelled in their assessments. Outstanding presentations marks were the reward for hard work!

To be a PADI dive professional is a challenge. Hard work, personal sacrifice and a willingness to learn and develop are just a few key elements required. The continuing path of professional diving development is further tested and assessed at Perth Scubas Instructor Development Course (IDC).

8 Days of personal and professional development in all areas of diving requires long hours of study and personal sacrifice.

When teaching these courses, I am always amazed and happy to see determination in students to reach the highest levels not only in Dive development but personal as well.

"Are you willing to change the person you are to the person you want to become?” is the motto I relate to the candidates.

So, are you ready to take the next step into Professional Dive Development? To become a PADI Open Water Dive Instructor?

Perth Scuba is the only Career Development Centre in Western Australia, advice from our Development Team is always available. We are here to support your personal and professional journey into the world of Diving.

Divemaster is the beginning, where will your journey end, that is your choice alone!

So, Congratulations to

Harriet, Rob, Niels, Itamar, San, Devan and Shaun …….

How many calories does a SCUBA DIVE burn? 

Ever wondered how many Calories or Kilojoules one Scuba Dive burns? These days, with everyone on stay fit and eat right regimes, you will have noticed that almost everything is turned into Kilojoules burned and Kilojoules consumed. The very fear of eating a freddo frog (70 Calories / 293 Kilojoules in a 30g frog!) sits in the back of your mind while you sit and enjoy it – knowing that it will take a bit of exercise to “work it off”.

Well… For those of you who are lucky enough to enjoy our awesome sport of Scuba Diving, you will be happy to know that we have done the hard work for you and have come up with those magical numbers that will make you feel a whole lot better about the big lunch you have onboard Blue Destiny between dives. 

Just to be fair to those other “not so much fun” sports and activities, we’ve included the Kilojoules burned for those too.

• Please note – These measurements are based on 60kg person and an 85kg person * I will give you a link to personalise your own weight vs activity so you can get a more exact number of Freddo Frogs you can eat after each activity to be “Kilojoule neutral”. 

Snorkelling : (Kilojoules burned per hour) 

60kg – 1412kj  (4.81 Frogs)

85kg – 1712kj  (5.84 Frogs)

Skateboarding : (Kilojoules burned per hour) 

60kg – 1412kj  (4.81 Frogs)

85kg – 1712kj  (5.84 Frogs)

Body Boarding: (Kilojoules burned per hour)

60kg – 847kj    (2.89 Frogs)

85kg – 1027kj  (3.50 Frogs)

Swimming : (Kilojoules burned per hour) * Freestyle fast or Breast stroke (same)

60kg – 2826kj  (9.65 Frogs)

85kg – 3424kj  (11.68 Frogs)

Spearfishing : (Kilojoules burned per hour)

60kg – 1757kj  (5.99 Frogs)

85kg – 2489kj  (8.49 Frogs)

Paddle Boarding: : (Kilojoules burned per hour)

60kg – 847kj    (2.89 Frogs)

85kg – 1027kj  (3.50 Frogs)

Scootering:  (Kilojoules burned per hour)

60Kg – 1412kj  (4.81 Frogs)

85kg – 1712kj  (5.84 Frogs)

Surfing : (Kilojoules burned per hour)

60kg – 847kj  (2.89 Frogs)

85kg – 1027kj (3.50 Frogs)

Scuba Diving: : (Kilojoules burned per hour)

60kg – 1980kj  (6.75 Frogs)

85kg – 2399kj  (8.18 Frogs)

So there you have it! 

Swimming is the most physical activity with the highest Calories / Kilojoules burned per hour followed by SCUBA DIVING!! The great part about Scuba diving is that the exercise is happening while you do what you love the most. Now if that isn’t a great reason to go diving, then what is?

And before you say anything about the author of this article… Its been a long time between dives and not so long between Freddo Frogs ok?
