The unique, serene environment and the sensation of floating effortlessly and silently through it are ineffable. Most people take up scuba as a hobby to get away from the noise and doldrums. This sport refreshes the mind and body and makes you more active. Each time, when you prepare to dive deep down the water, you do not know what's waiting for you inside. This element of surprise is always contained within the sport, and this is another reason for its increasing acclam

Here's where things get a bit confusing. The entry-level TomTom Spark only includes the features listed above. The TomTom Spark Cardio adds a built-in optical heart rate sensor. The TomTom Spark Music doesn't include a heart rate sensor, but does include 3GB of storage for songs. If you want both heart rate tracking and music storage, there's the TomTom Spark Cardio + Music.

It is also recognised that regulators frequently leak a little salt water, and that some of this may be nebulised into a mist during breathing. This mist can irritate the airways and precipitate narrowing in vulnerable individuals.

'I was trying to set my camera up to film this sea spider and then I noticed this little thing flashing on the rocks, I'd obviously disturbed it while I was trying to look at the spider and it was flashing at me to go away,' Mr Heuer told

In this day and age where people do not want to take responsibility for their own actions, the most prudent thing for a dive physician to do when an asthmatic walks into his surgery is to say “Bog off, you're unfit”.

In the context of asthma, most dive physicians would agree that the more active the asthma, the greater the risk in diving. Those candidates who suffer serious attacks, wheeze relatively often or who use reliever medications regularly, cannot be considered for diving, even on an informed consent basis, because rightly or wrongly, the risks are perceived to be too high.

The TomTom Spark line of watches consists of six models in total, all of which include GPS, all-day activity tracking (steps, distance, calories burned, active minutes), automatic sleep tracking, Bluetooth to connect with smartphones, interval training and a water-resistant rating of 5 ATM, so you can . TomTom said that an update slated to arrive by the end of 2015 will also add smartphone notifications and continuous heart rate tracking.

Since, 3/4th of earth is covered with water, you can find numerous delightful spots for carrying this out. Scuba diving may be full of surprises but, this isn't surprising that it is an all-time favorite of adventure lovers. However, one thing should be borne by the divers, and that is the safety issue. Whether you are a beginner or a professional, ensure that you have the right scuba diving equipment because they are the most essential elements of this act Underwater photographer Duncan Heuer and his girlfriend were on an evening scuba dive 50 metres from shore at Camp Cove Beach in Watsons Bay last week when they spotted a blue-ring octopus hidden in the sand.

With these candidates, a long discussion about the potential risks in diving implied by their asthmatic history, is usually followed with tests to check that neither exercise nor the breathing of nebulised salt water (at the same concentration as sea water) provoke airway narrowing. If these tests are negative and patients exhibit a clear understanding of the issues and wish to proceed, then we should be happy for them to dive. Unfortunately, to conduct and document this process properly is a time consuming and expensive exercise, but at least it's better than being told to “clear off” without so much as an explanation.

Cost is another favorable factor of this activity. The tools and technologies required for this sport has become cheaper and thus, it has opened up for everyone. The hobby, which, at one time, was only meant for professionals with considerable money, is now available t

'It obviously didn't like it too much… If we're trying to photograph them, we don't spend too much time trying because it's quite stressful for them,' Mr Heuer told The octopus species has claimed the lives of at least three people, including two in Australia and one in Singapore.

There is concern that an asthmatic may suffer narrowing or blocking of small airways during a dive, and that expansion of any trapped air during ascent may lead to the same problem. There is also concern that use of reliever medication, such as Ventolin, prior to diving may cause the lungs to be less efficient at filtering out the venous nitrogen bubbles we all have after dives. Some ex-sufferers previously prevented from diving can now dive, after making an informed choice about the possible risks. To understand this, it is first necessary to understand what asthma actually is. Asthma is a condition affecting medium to small airways in the lungs. In asthmatics, these airways are prone to narrowing, which impedes the flow of air into and, in particular, out of the small air sacs (alveoli) where gas exchange occurs. The trigger for these events is often an allergic response to a specific stimulus.
