SOURCE: Prescription Scuba Mask

The inserts would be specifically for your eye prescription and are bonded to the lens. You can even get bifocals done for your mask and also correct for astigmatism. Your specific prescription can be fit into any dive mask that you choose so there is no need to buy a new mask. prescription scuba mask Manufacturers also offer scuba masks with lenses already premade and the same prescription in both eyes. You choose the prescription that fits your needs. Some divers find this adequate to use underwater. The premade prescription mask would obviously be cheaper than custom made scuba diving masks. Personally, I wear contact lenses when I dive and have had no problems (besides losing one after I surfaced and got hit by a wave). I wear the daily soft lenses and don't notice them when I dive. I've never dove with hard contact lenses so I do not know how they would respond to pressure. If you wear lenses, you should consult your eye doctor to see what they recommend in your case before you dive with lenses for the first time. Let them decide whether you would be better off with a prescription scuba mask or diving with contacts. One site I found which seems very professional is www.prescriptiondivemasks.com. They even have a testimonial from Cathy Church, the renowned underwater photographer, on their site so it can't be too shabby.

SOURCE: How and why scuba gauges give a diver critical information while scuba diving?

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

SOURCE: Why do scuba diving pressure gauges reach 5000 psi if a tank may only be filled to a max of around 3200?

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.

I am in Clearwater Florida. Is there someone who services Dacor regulators in the area?


Hi there you can do few things. Visit a Commercial Diving Company and find out a Dive tech ( Mech) and ask him for proper location. Or in Florida there is an Commercial Diving academy available. There you can visit and repair your regulator in less money. I search in Google but i did not find any proper place for repairing. I am a Saturation Diving Technician and I believe if you visit my mention place then you will get the proper service and also collect some knowledge about how to set a regulator. Thanks . Regards, Rajdeep.

Guidelines to Scuba Regulator Purchase


The scuba regulator is employed in an open-circuit scuba set. Said scuba equipment reduces high air pressure conveyed by the diving cylinder to the first stage and feeds breathable gas to the diver through the second stage's mouthpiece. Also called pressure regulator or demand regulator, the scuba equipment is one of the essentials to diving that determines breathing quality and inhalation effort during the dive. But given the different types of regulators and the pertinent design of its first and second stage components, how should a neophyte diver - or even a seasoned diver at that, choose a scuba regulator that incorporates user adjustment and delivers a venturi-assisted air flow in its features? Consider your diving purpose and frequency. Better yet, take note of the following criteria to guide you in your purchase: 1. The Scuba Regulator's Mouthpiece. Check the specifications if the regulator is outfitted with a patented orthodontic mouthpiece. This implies that it is ergonomically-designed to accommodate an overbite or underbite by the human mouth. An ergonomic mouthpiece helps reduce fatigue in the mouth and jaw area, particularly in the cruise of lower depths and extended dives. 2. User Adjustment Settings. There are optimally-designed scuba regulators that are outfitted with adjustment levers to therefore allow divers to finetune valve settings in order to provide the least possible inhalation effort throughout the dive. One notable scuba equipment is the Aeris AT 400 Pro Regulator that is equipped with an adjustable second stage. 3. Weight of the Scuba Regulator. Visualize yourself on a dive and using just any other type of scuba regulator. Is the regulator bulky to considerably increase drag and cause jaw fatigue or is it buoyant enough for you to carry around with your mouth? Lightweight scuba regulators use polycarbonate thermoplastics for its housing to make the scuba equipment compact, sturdy and corrosion-resistant that makes them fit for extended use. 4. Nitrox Compatibility. This entails an ocular inspection of the cylinder tank (Nitrogen and Oxygen proportions) and scuba regulator (Nitrox compatibility) specifications. As a matter of convention, most regulators are suited for nitrox mixture use out of the box; containing the standard, maximum proportion of 40% Oxygen (in terms of volume) but then again, there are gas mixes supporting leaner proportions of oxygen such as the trimix. Therefore, check if the scuba regulator supports the gas mixture configured for your diving cylinder prior to purchase. 5. No-Contaminant Feature. As much as possible, choose a diving regulator that has been manufactured using Dry Valve Technology (DVT). DVT operates through an automatic valve that prevents contamination of the first stage mechanism to thus prevent regulator flooding and the entry of moisture or dust particles. This likely improves scuba regulator performance and extends its useful life. 6. Air-Sharing Feature. This feature often associated with octopus regulators (used as a spare demand valve or alternate second stage) will prove to be most helpful during diving emergencies such as a free flow or during diver rescues. High performance octopus regulators such as the Aeris Gyro Octopus Regulator are designed lightweight and with air-sharing feature, while sporting an inline swivel for convenience mounting and flexibility

Do I need a scuba regulator and if so, how do I know which one to buy?


"Because the scuba regulator is such a vital piece of gear many scuba divers choose to buy their own scuba regulator instead of renting one from the dive shop. When a scuba diver has used a few different scuba regulators, on numerous dives, he will notice that they all have slightly different ""action"" - some feel looser or tighter, some will deliver air more forcefully, others will have a slight ""suck"" to them. The goal of all regulators is the same: to deliver air on demand at ambient pressure. Comfort with a scuba regulator depends on how the diver breathes; which is different for everyone. Though a helpful clerk at the dive gear shop can recommend ""the best"" regulators, from the most respected manufacturers, in truth no one can tell you which regulator ""feels right"", except you. Sponsor Links [what's this?] As a novice scuba diver renting or borrowing equipment from a dive shop always take note of what scuba regulator you are using and whether you like how it feels. When you find the one which makes your breathing feel effortless remember its make and model. When you decide to buy your own scuba regulator you will know which one to get. When shopping for a scuba regulator here are some things to consider: See our choices for scuba regulators * Ergonomic design and easy to hold * A purge button which is easily pressed even when wearing 6mm neoprene gloves * External controls which let you make fine adjustments to air flow * Non-corroding metals like titanium or chromed brass * Diaphragm vs. piston mechanics. Many divers prefer diaphragm regulators for its smooth movement and its moving parts are less * Balanced vs. unbalanced regulators. Almost all regulators are balanced. Do not buy an unbalanced regulator. * Always buy new. Do not pick up a cheap second-hand regulator; it may be faulty or reconditioned * Look for a warranty * Swivel joints on the second stage offer improved ease of movement * Hose should be soft and flexible "

Scuba suit need?


"Wet suits and dry suits are very important when it comes to scuba diving. Your normal body temperature hovers around 98.6F (37C). If you are scuba diving in water that is cooler than your body temperature your temperature will drop. In all water, even the warmest, tropical waters, you will need thermal protection, like a wet suit, dry suit or dive skin, to keep warm and to keep safe while scuba diving. The cold affects our ability to think and our physical response time slows, which can lead to an accident. Warm tropical water will begin to feel cold after prolonged scuba diving, so it is always a good idea to wear light insulation at a minimum. When choosing thermal protection, like a wet suit or dry suit, you need to consider the following factors: Water temperature Your activity level during a dive Your body size You should always wear more insulation in colder water and lighter insulation in warmer water. Your level of activity can be a good indicator of how much insulation you should wear during a scuba dive. The more active you are during a dive the more heat your body generates and the warmer you remain throughout your dive. Larger scuba divers may need less insulation than smaller scuba divers and small, muscular scuba divers may need less insulation than larger scuba divers. It is important for you to try different amounts of insulation in differing water temperatures to determine what you need. Some scuba divers need more insulation than others, regardless of activity or size. Some scuba divers can dive in tropical water wearing only a lycra body suit, commonly known as a dive skin, while others need a 2mm wet suit. Some scuba divers can dive in cold water wearing only a 6mm wet suit, while others need the protection of a dry suit. If you are scuba diving in water below 55F (12.7C), a dry suit is the warmest type of thermal insulation available. Dive skins, wet suits and dry suits also protect your skin from cuts, scrapes, abrasions and stings which can occur while you are scuba diving. A simple brush against specific forms of coral and fish can cause painful irritations and burns on bare skin, but may not be noticeable or even occur, if your skin is protected."

Scuba mask maintenance


" 1. Use a defogging solution before every dive, even when diving more than once in the same day. This will prevent your scuba mask from fogging during a dive. You can purchase a commercially prepared defogging solution from any reputable scuba diving retailer. Squeeze a drop or two onto the inside lens of your mask and gently rub the solution around to cover the inside completely. Dip your mask briefly into water, swirl the water around the inside of your mask very quickly and empty the water from your mask. A quick rinse will remove any excess defogging solution from the inside of your mask. You do not want to get defogging solution in your eyes, especially while diving, since it can cause stinging and irritation. If you don't want to use a commercially prepared defogging solution you have a defogging solution readily available and it's free, your saliva. Your saliva will prevent your scuba mask from fogging just as well as any commercial defogging solution. The enzymes in your saliva stick to the lens of your mask like a commercial defogging solution and you will never find yourself without a defogger while on a dive. 2. Never lay your scuba mask face-down on any surface. Salt, sand and grit will scratch the lens of your mask. Always place your mask face up when you are not wearing it or if it is not in its hard case. 3. Rinse your scuba mask in clean, freshwater after each dive and dry it thoroughly before storing it in its hard case. After a dive, your mask will be covered in a salty residue and/or dirt. This must be rinsed clean to prevent the silicone on your mask from degrading. Your mask must be completely dry before storing it to ensure the silicone stays clean and odor-free. 4. Always store your scuba mask in its hard case. If your mask did not come with a hard case purchase an after-market hard case. This will protect your mask from dirt and abrasives and protect it while traveling. Always store the case out of direct sunlight. Direct sunlight will break down the silicone after years of exposure. 5. Periodically repeat the toothpaste treatment to keep the lens of your scuba mask clean. A good rinse after each dive helps to keep your mask clean, but to ensure there is no residue or grit left on your scuba mask you must properly clean it on a regular basis."

Scuba Gauges what do I need them for?


"A diver relies on scuba gauges to know three things: 1.-Depth 2.-Air Consumption 3.-Time Depth and Time are vital for nitrogen and air management. A scuba diver needs to know how deep he has been and for how long in order to judge the necessity and length of decompression stops and to calculate residual nitrogen for repetitive dives. The time of a dive is easily tracked using a scuba diving watch and the depth is tracked using a depth gauge. "
