Question about Scuba Diving & Snorkeling
Casa de goa
We can do many water activities in Goa such as swimming, scuba diving and much more and you can do a lot of things in a private yacht. You can do all these water activities in the sal river, backwaters, and on the Arabian sea island.
You should once try river cruise in goa for enjoying all these water activities.There are many cruises in goa but river cruise is best for those who want to do water activities.

Goa is really an amazing place to have fun with friends and enjoy your holidays. You will love the beautiful beach and enjoy many water sports like scuba diving and snorkeling. If you are looking for a good instructor you can check reviews online.
There are beautiful villas also you love to stay with your family and friends, especially the villas in Candolim. I have a great time there with friends.

Scuba gauges give a diver three very important pieces of information: 1. Time 2. Depth 3. Air Consumption This information enables a diver to stay within safe time and depth limits and avoid running out of air. There are many different devices on the market to help with this, from simple gauges to complex digital consoles. Time If a diver is not using a dive computer to monitor their nitrogen, they dive according to approved dive tables. To use dive tables properly, a diver needs to track their downtime. This can be done with a good dive watch. Two things make a good dive watch: water resistance and a rotating bezel. 1. Water Resistance. Good dive watches are rated to a depth in meters or feet (e.g. 200 feet) or a pressure rating in atmospheres (e.g. 4atm). Even though most divers probably won’t dive below 130 feet (the recreational dive limit), a good dive watch should be rated to 200 feet. Note: There is a difference between “water resistance” and “waterproof”. A “waterproof” watch is what you would wear in the shower, but would probably start leaking at 15-20 feet. 2. Rotating Bezel. A bezel is an adjustable ring on the face of the dive watch with a pointer indicator. At the beginning of a dive, the pointer on the bezel is aligned with the minute hand where it stays though out the dive. At the end of the dive, you compare the difference between the bezel and the minute hand to find out the length of the dive. The bezel should only move “counterclockwise”. It is possible to accidently move the bezel during a dive. Because of this, watchmakers make sure any accidental movement will turn the time in a conservative direction, making the dive longer rather than shorter. Depth Another important part of scuba gauges is a depth gauge. A depth gauge enables a diver to keep track of their depth even if they cannot see the water’s surface. Gauges can be either an analog (needle-and-dial) device or a digital device. Both work in the same way. They measure the surrounding water pressure and convert this into an accurate reading of your depth. Another feature of a good depth gauge is a maximum depth indicator. This tells a diver their maximum during a dive and must be reset after each dive. Air Consumption Another equally important part of scuba gauges is a submersible pressure gauge (SPG). This is connected to the first stage with a high-pressure hose and measures the pressure of the air in the tank. The SPG is much like the gas gauge on a car. At the beginning of a dive, a diver starts with a full tank. This should be about 3000 psi or 200 bars. As the diver breathes during the dive, the gauge will move slowly downwards. This allows the diver to have enough air left in the tank to: 1. Make a slow, safe ascent 2. Make any necessary decompression stops 3. Inflate their BCD once at the surface 4. Breath from the regulator if the surface conditions are rough A submersible pressure gauge also allows a diver to stop diving with air still in the tank. This keeps contaminants from entering the tank due to no air pressure. Wrist Depth Gauge Scuba gauges come in two basic styles. Stand alone gauges or gauge consoles. Stand alone gauges such as a wrist mounted depth gauge or a submersible pressure gauge attached to the first stage of a regulator are great backups when using digital gauges. Gauge consoles allow divers to have all their gauges in one place. Although less easy to read, analog gauges sometimes give slightly more accurate readings than digital gauges, particularly at shallow depth. Submersible Pressure Gauge Choosing Scuba Gauges When choosing scuba gauges, remember to look for: 1. Easy-to-read numbers 2. Luminescent dial or back lighting options 3. Rotating/swivel mounting 4. Easy disassembly for cleaning or replacing parts 5. Good warranty

Scuba tanks can be filled well past 3200psi. When they do a hydrostatic test it is well beyond any pressure that any dive shop will fill a tank to. The highest I've seen the pressure get in my tank is 4000 and that is when the filler at the dive shop forgot about it.
