Essential Dive Watches for Serious Divers

Dive watches, also commonly known as diving watches or diver’s watches, were designed for underwater diving. The first dive watch invented was during the 17th century.

It features a water resistance about 200 to 300 m or 660 to 980 ft. deep but because of high technology it can go much deeper. Modern technology has a great contribution that allows the resistance of diver’s watches to go beyond 980ft from the ocean.

Until now, the manufacturing companies never stop inventing the best diving watch. It is commonly used for scuba diving by the divers. There are several kinds of dive watches that were invented by different companies. These products may differ depending on the purpose of the user and their profession.

It is no wonder that the watch that remains most popular is the dive watch. A timepiece designed for wet work are suited for adventurous people who are trying to discover the underwater world. Time and depth is related with each other because when you go deeper, your times run out. The longer time you stay long the chance you take the risk.
Every diver needs a watch to manipulate their time under the water to prevent shortage of oxygen. A dive watch glows in the dark even on a deeper part of the ocean that is very dark, they can see the time. It can also be fashionable even under the water because of the unique design.

The watch is not just for informing about the time but it is a part of the lifestyle of the users. Expensive watch is more popular now because of its water resistance for about 1000 meters. It is made of high quality materials so it has the capacity to stay longer under water pressure. A dive watch has a distinctive design that everyone will love. Time is precious so everyone wants to use an excellent timepiece.

Choosing Scuba Computers or the Dive Table

Back In The Day

Diving back in the 1970’s, we used the standard no decompression US Navy dive tables because that is all that existed. The Navy tables used a six tissue compartment saturation model table and were not designed for repetitive scuba diving.

Today’s dive table uses a twelve tissue compartment saturation model table with research and testing done by Haldane. Most modern scuba diving computers us a 12 tissue compartment modified Haldane table algorithm.

diving with a computerWhat you need to know is, do they work and are they safe?

The answer is yes. Both dive tables and computers will help you dive safer and may keep you from getting decompression sickness. You may notice I said MAY keep you from getting DCS. Remember, everybody’s physiology is a little different and nitrogen absorption rate will vary from person to person.

 

The benefits of the scuba diving computer

The benefits of the scuba diving computer are numerous and make diving in general, safer. Scuba diving computers do all the work so you can have all the fun. Some of the benefits are:

  • Automatically keeps your dive time and surface intervals
  • Computers calculate the tables for you- Auto calculate residual nitrogen times groups
  • Calculate the tables by the minute/second not every 10 minutes
  • Uses multi-depths on single dives
  • Allows for Air and Nitrox No “De” calculation
  • Signals ascent rate speed
  • Remote air pressure gauge

All scuba diving computers today perform a number of basic functions; the first is keeping the total dive time and surface intervals automatically. Second, they all calculate the dive tables and the residual nitrogen times for you, eliminating all the manual calculations and possible mistakes.

Because Diving computers use an algorithm that is recalculated every minute of your dive and at every depth you reach on the dive, you get a more realistic custom dive decompression schedule for every dive.

One of the easier to use computers that we recommend can be worn on your wrist like a watch. It is the SUUNTO D6i Novo.

Remember, dive tables are based on ten minute NO “De” time periods and 10 foot depth schedules and calculating your decompression and residual Nitrogen times. Plus you have to calculate it manually after the dive and don’t get up to the minute results while you dive.

Ascent rate alarms and indicators keep you from surfacing too fast and one of the best features that most divers need. Most divers don’t realize how slow 60ft per minute is and how really slow 30ft per minutes is. Try walking 30ft in a minute’s time just to see what I am talking about.

New designs in scuba diving computers include accommodating for Nitrox diving and include wireless air pressure gauges as part of the computer.

One of the best things about a dive table is that you can get it for less than $20.00. When you start diving you will have to be able to master calculations for dive no decompression and residual nitrogen times to get certified.

The cost difference between a Nitrox compatible scuba diving computer and one that is air only is so little these days that you should buy a Nitrox one even if you are not Nitrox certified.

The most expensive Scuba diving computers are all air pressure integrated and most of those are of the wireless variety. I personally am still on the fence about the wireless (battery powered), remote air pressure integrated scuba computers and would still use a standard pressure gauge as a backup.

Computers can be mounted in your gauge console or worn as a wrist watch. In fact new designs are smaller and more watch size making it easy to wear as a watch when you are not diving.

Remember, scuba diving standards always recommend every diver has a computer and that they are never shared between two divers on the same dive.

You can easily spend $600 to $1000 dollars on a scuba computer but there are certainly good scuba computers the will do all the basic functions and keep you safe for less than $200.00.

Diving in the Solomon Islands: Gizo

The Solomon Islands are generally recognized as offering the best diving in the world and Gizo’s provides an ideal and picturesque location among the hundreds of small tropical islands of the Western Province. It’s beauty and quality diving is unsurpassed.

gizo water frontThe Gizo Hotel’s waterfront location enables one to take full advantage of this idyllic setting and sheltered dive sites are always in easy reach. It has comfortable accommodation, a great upstairs bar with a view and lovely service.

There are a number of well equipped dive operators in the Solomons to help you discover pristine walls, reefs and pinnacles. There are also numerous wrecks from WWII that provide superb diving. Last but not least there are the massive amounts of fish waiting to be photographed.

The islands provide top quality service by friendly staff including the daily carrying, rinsing and drying of all your dive equipment. We also assist with checking up on your travel arrangements, confirming flights etc. Staff are available 24 hrs daily.

Fast dive oats are often a luxury in the tropics but where available you should definitely seek them out. They are capable of taking parties of up to 10 divers and will take you safely through calm waters to our best dive sites only 10 to 20 minutes away.
