Travel Light with Scuba Gear


With lightweight scuba equipment for sure you have to make some compromises on what you normally prefer. You might consider it though, to avoid having to pay a lot extra for luggage overweight on top of your plane ticket. Besides that, you travel more comfortable. Let's go through the different pieces of equipment to see where and how we can reduce weight.  read more »

Reasons of a "wet breath".

A "wet breath" is defined as taking in water together with air through the regulator while you breathe. It can be just annoying if it's a bit, up to making the regulator useless, being forced to swap to your alternate air source. To go a bit deeper into the reasons of a "wet breath". The vast majority is caused by the diaphragm, mouthpiece or the exhaust valve. All concern the second stage.  read more »

Groupers and moray eels hunt better together

Fish of two different species have been filmed helping each other to hunt. It is the first known instance of two unrelated species hunting cooperatively, except for humans. Like a hunter bringing a dog to flush out rabbits, groupers entice moray eels to hunt with them. Surprisingly, this might also shed light on how our own species evolved.  read more »

How to repair a broken scuba mask buckle

Most people pull the strap of their mask way too tight, not surprisingly resulting in a leaking mask (yes, it makes it worse) and breaking the little plastic pin of the mask buckle. The diving center ends up with lots of masks with loose straps on one side. Instead of needing two broken masks to make one good one, I will explain how we can repair all these masks with a little effort and no cost.

You just need a paperclip (the big type), an empty ballpoint pen filling (the small ink tube inside) and some basic tools.  read more »

Compass use. The most applicable.

After you’ve done the “square” swim in your advanced course, you may doubt the practical use of the underwater compass. When will you swim squares? So, some more practical examples of the techniques used by the dive guides.  read more »

The difference between “dynamic” and “static” neutral buoyancy and some buoyancy exercises.

Buoyancy control: Photo: Adam ButlerBuoyancy control: Photo: Adam ButlerNeutral buoyancy, being weightless, is theoretical for a breathing diver on an open circuit. We will be slightly positive breathing in, a bit negative breathing out. This is an asset we can use to “micro” regulate our depth, giving us greater control by breathing consciously.  read more »

Pre-dive checks. Why and how.

It is widely recognized that performing a pre-dive check can prevent most of the dive accidents that happen. As you remember from your Open Water Course a pre-dive check should be conducted on your buddy before entering the water previous to each dive. We try to remember it with sentences like “Burger With Relish And Fries”, not to mention the dirty ones, standing for BCD, weights, releases, air and a final OK. But, but, but ….. harsh reality shows us that forgetting is so much easier than remembering.  read more »

A bit about recreational equipment set up. Within the standards

A surface marker buoy (SMB)A surface marker buoy (SMB)Why oh why most dive shops and dive centres still mount the alternate air source (octopus) on the right side? The right side is, however, in my opinion, the wrong side. Sharing air with somebody in front of you results in a “S” in the hose.  read more »

Fining techniques. The most applicable.

Up and down, that’s the way we learn to use our big blade somewhat stiff open-heel fins in the Open Water course. The fins are designed for this use, and therefore, it is this “normal” fin stroke that is the most effective. The one to use in most circumstances, long and slow.
However, sometimes this high efficiency is not necessary, and we prefer another technique.  read more »

Entry and exit techniques

In the Open Water Course, we have learned several entry techniques. To resume; sitting entry in the swimming pool or from a low or floating jetty, backward roll from rib boats and the giant strive from not too high jetties or boat platforms. All of which with full gear, mask on, regulator in and positively buoyant. I would like to add some.  read more »

Approaching sea life. How getting near and how near is near enough?

On our first dive we are so occupied with ourselves that we don’t notice the sea life to much. The person that saw a whale shark on his first dive only told his wife later that he had seen something big and his ears hurt.

As we gain experience we get more attention for the surrounding. We tend to go closer and closer to the sea life  read more »
