Hana Cho scuba instructor Asia Divers

Last dive with Hana Cho

My last dive with instructor Hana Cho

It has been quite a personal journey with Hana Cho. I can honestly say that I am immensely proud of her as both a diver and as a PADI Scuba Instructor, as I have had a key role in her development and education during her Divemaster course and helping her prepare for her IDC course and consequent instructor internship.

She is without doubt one of the best divers I have seen. Not only is she the consummate dive professional but her self marketing skills are second to none, as she has a very successful blog from which she has captured the imagination of many new divers and Divemasters in a very short period of time. She has been the most successful I have ever encountered.

I am sure that anyone diving with her will learn thoroughly and properly to standards unlike many of the instructors on Koh Tao, Hana cuts no corners in her diver training.

So I took these photos on our last trip together at Chumphon Pinnacle and White Rock. This may have been our last time.

How to pack your scuba kit bag

How do I put all this scuba kit into my gear into my kit bag?

There are many ways you can pack your kit bag with all your gear and it depends upon whom owns the equipment, whether or not you take all the equipment, distance to carry the gear, where you will be kitting up.

For diving with us and using our shop gear we would recommend packing your kit in the following manner ;

  • Fins in first – Place your scuba fins at the bottom of your kit bag. We place fins at the bottom of the kit bag fro two reasons
    1. Fins are the things you will need last
    2. Fins are cheap, plastic and durable. Therefore fins can protect the rest of your scuba kit from damage through transportation to and from the dive site.
  • After checking your scuba regulator thoroughly make a loop with the hoses and place inside of your BCD in the middle, then fold the BCD sides around it for padding & protection
  • Having size checked & adjusted your mask attach your snorkel to the left hand side then place inside a folded or rolled wetsuit and place this also inside your BCD on top of your regulator set.
  • Place BCD inside of your kit bag, right on top of your fins.
  • Zip her up your good to go diving.

Washing a Scuba Regulator after use

How To Wash Scuba Regulators After Use

Why Wash Scuba Regulators After Use?

It is very important to wash scuba regulators thoroughly after use, to help preserve its general condition, help to avoid unnecessary or early servicing and lastly for good hygiene practices by preventing dirty smelly regulators being used or from colds / infections being passed form diver to diver

Once a regulator has been immersed into water and/or breathed from by a diver then it will require washing after disassembly as salt water is extremely corrosive to all metals and could corrode the first stage housing or moving parts. not only this but the diver my deposit saliva or other matter within the second stage that is far from pleasant to encounter a few days later

We will be showing you how to rinse the scuba regulator first stage and flush out the regulator second stages after use.

Check and Double Check First Stage Dust Cap
scuba regulator first stage dust cap scubapro

scuba regulator first stage dust cap aqualungBefore you immerse the scuba regulator in your wash tank double check that the if the first stage uses a dust cap that it is located and secured properly by tightening the thumbscrew on the regulator yoke. Please bear in mind its name is “Dust Cap” : – Is designed to prevent dust and sand and dirt from clogging the first stage. A Dust Cap is not a water cap and therefore is not
designed to keep water out of the first stage when it is not attached to a tank,

so be careful to
understand whether or not your dust cap is suitable to prevent water from entering the first stage chamber if you immerse it fully into water. Generally they do not. So with that in mind we do not recommend immersing either our Aqualung or ScubaPro first stages into the water for rinsing purposes.

Rinse Regulator First Stage

Approach wash tank and carefully lower first stage close to water held in such a way thet the thumbscrew of first stage is pointing downward toward the water, then pour water over the first stage to flush out the salt/chlorine form this unit. Once you have done this a few times pull the first stage out and shake excessive water off.

Rinse Regulator Second Stages

Take the second stage and immerse it in fresh water and waft it fairly vigorously through the water. Do Not press the regulator purge button when the regulator is immersed without being attached to a scuba tank or else water will enter and stagnate within the second stages low pressure hose leading to unpleasant smells and tastes as well as accelerating the degradation of the hose itself. If you have pipe cleners or toothbrushes then use these to clean the mouth pies both where the diver bites upon i but also inside the exhausts and inlet to rmove any debris within, in the abscence of tools use fingers and rub thoroughly. Dont forget that there are 2 second stages, the black and yellow one too, they will both need rinsing in this manner.

Rinse Submersible Pressure Gauge

Simply immerse the SPG in water and gently swill it around and then rotate the spg on it hose whilst immersed in fresh water to clean the joints

Rinse Low Pressure Inflater hose

Immerse and gently swill around and then pull the bayonet fixing back and forth a few times in water to clean the ball bearings contained within the collar.

Hang to dry

Once all parts of the scuba regulator have been rinsed off with fresh water, carefully shake out the water within the second stages and first stage before hanging to dry on a tank rack or other suitable location.

sea snake at surface from divers perspective

Do Sea Snakes Bite and Kill Scuba Divers?

Can banded Sea Snakes bite and kill divers?

“Sea Snakes have small mouths so can not bite humans except the skin between fingers and ear lobes” – Fake scuba myth!

An old friend of mine, Peter from New Zealand once mistakenly jumped onto a sea snake in the water from his boat when he went for a swim with some friends one evening. Peter was immediately bitten in the neck, luckily after being rushed to hospital to receiving a shot of antivenin and a few days rest within he lived to tell his tale. So sea snakes are able to bite humans Banded sea snake hunts on sea bedanywhere on the body, despite appearing to have a very small mouth. Do not believe this scuba divers myth that the sea snake  can only bite you between fingers and exposed ear lobes and therefore think it may be safe to do what you like to a sea snake so long as you cover your ears with your hands, as this is not true sea snakes can bite you anywhere if they so choose to do so.

Do Scuba Divers Get Bitten by Sea Snakes?

It is a very rare occurrence that a conscientious scuba diver is bitten by a sea snake, generally sea snakes have no interest in people and normally completely disregards divers presence in the water. However if the snake were to be antagonised or harassed by a diver the sea snake may feel threatened and might well defend itself from the diver. However fisherman in the pacific are the humans at most risk of bites when pulling catches from nets without looking when there is a snake caught within.

Are Sea Snakes Poisonous?

The banded sea snakes hunt in the sea for small fish and moray eels and returns to land to rest and digest its catch. They come equipped with a powerful neuro toxin to disable its prey.

Symptoms of a Sea Snakes Bite

In humans the toxin could give symptoms such as nausea, vomiting, swollen tongue, lethargy, muscle pain, paralysis, convulsions, and potentially death.  At the site itself not much noticeable happens, except possibly 1 – numerous puncture marks.

Sea Snake Bite First Aid

As a bite from a Sea Snake is potentially life endangering, it is important to treat the wound as quickly and appropriately as possible.  Fatality rates from sea snake bites are very low between 3%-25% depending on bite location and quantity of venom injected. But first aid steps should include

  1. Direct Pressure / Pressure Bandage
  2. Immobilise affected limb and keep below heart level
  3. Keep patient warm and relaxed and evacuate to EMS for antivenin shot (within 8 hours of bite)

Do not attempt to cut or puncture the bite site to suck out the venom like you may have seen in Hollywood movies

When are Sea Snakes around Koh Tao

We often get asked by novice divers or divers new to Koh Tao, what should they do if they encounter a sea snake. The banded sea snake also known as the Black-Banded Sea Krait (Laticauda semifasciata) is rarely sighted here on Koh Tao however it is seen most frequently between the months February until April here, but it may be encountered at any time during the year.

Diving conditions near perfect on Koh Tao

The Rain Stopped and Its Now Sunny, Hot and the Visibility is Approaching its Best

You may have heard of the severe weather Koh Tao endured a few weeks back. The monsoon hit hard for 10-14 days causing massive flooding and damage to the islands infrastructure, high winds brought waves and poor visibility. But the weather changes from day to day and now we are fast approaching the best months of diving on Koh Tao.

Since the rain has stopped falling, the clouds have gone away and the sun is shining brightly. Not only has the island now fully recovered from some structural damage on land but the diving conditions are wonderful again.

Diving Conditions near perfect

Not only is there no wind meaning there is not even a ripple on the surface, but with bright sun our dive are much lighter brighter and more colourful too. The water temperature is still a clement 28C. We expect the temperature to rise up to 31-32C. Visibiity is running between 15m-30m depending on site and time of dive.

In this part of Thailand the hottest months are March through to May and these are the ideal times to book your trip to Koh Tao. You can learn more about Koh Tao seasonal weather here.

Not so many westerners take holiday over this period and so island is expected to be fairly quiet compared to Christmas and New Years holiday periods. Making the dive sites less populated with divers so you can really get to see more underwater marine life.

Chinese Instructor Course with Asia Divers

Fay Hee has been accepted by PADI for the CDTC February 2017

Our Chinese team grows stronger with each passing day. Team leader and PADI MAster Instructor Fay Hee submitted his business plan at the end of 2016 to PADI Asia Pacific and I am very pleased to report that he was accepted for the Course Director Training course in February 2017.

Chinese Language IDC from April 2017

Once he has completed and passed the Course Director Training Course, Fay Hee will be offering monthly Chinese Instructor Development course at Asia Divers Career Development Centre.

We currently have 6 Chinese Instructors in their team teaching over the Chinese New Year 27 January, as it is the most common time for annual holidays to be taken.

The Thai Consulate in China stopped issuing Thai Tourist Visas as they had already issued over 800,000 for this new year period.

With large numbers of Chinese tourists coming to Thailand it is a very good position for Asia Divers to host Chinese Instructor Courses as they become the dominant nation of visitors this year.

Monsoon Rain Damage

Extreme Weather Hits Koh Tao

Monsoon Extreme Weather Hits Koh Tao

This years monsoon is in full effect here on Koh Tao brining heavy winds and rains have hit the tiny island and quite literally battered it constantly for 3-4 days causing damage to property, roads, buildings and infrastructure.


Roads Become Impassable

The torrential rain has created streams and waterfalls that have become rivers that have caused subsidence and washed away the sand underneath buildings and road infrastructure. Travel on the island has become difficult and some routes have become impassable such as toward Him Wong, Aow Leuk. In Fact even going along the main road from Mae Haad to Sairee could only be done with 4 wheel drive vehicles with high clearance.

Relations worry about their loved ones on Koh Tao

Local Westerners Volunteer Beds and Rescue Assistance

But with thanks to the 24 hour work from Koh Tao Rescue most stranded residents or those in medical need have been reached and assisted to shelter and clinics.

Local business’s such as Indie Hostel and Good Times Hostel have offered free beds to those who were stranded without being able to get home offering these to locals on facebook.

Power outages have been common across the island. Fortunately these outages have not lasted too long. Luckily we have back up generator on resort, but internet access has been affected most people can still get internet through mobile packages.

Currently the ferry services have so far continued to run and no word of cancellations so guests should still be able to leave but be sure to have your seat booked as many boats are already fully booked up.

Taxi services leave resort 10:00 / 14:00
