General Information About Tankless Diving
The amount of time you can spend underwater at any depth using the above units is dependant on your battery. Using any 12v battery this is known as its ‘operating amperage’ (how much beer is in the glass?). The higher the amperage the longer you can dive. For example lets say you have a 12v battery with 120A/H, If you were diving at say 7metres (22foot) you could hang around there for probably 6hours+. Now you must realise that different people breathe at different rates so it is difficult to give precise figures, eg a woman normally breathes less than a man. Try it at home, 2 people breathing at ‘rest’ say for a minute keeping a mental count of how many breaths each takes in the minute, now compare the results. Normally women have a lower rate than men. Now I haven’t taken into account people's age or physical size, or their level of fitness. There are a lot of factors that impact your breathing rate. Suffice to say that if you were diving for say 6 hours (why would you?) and wanted to do a lot more with confidence, why not surface take a break and just change batteries and when you're ready go back in.
Remember our recommendation above about diving training, if you plan to go down beyond the depth of your boat's hull, it would be wise to head our call, you never know you just might learn something that could save your life or the life of someone else who may get into trouble.
Most customers upon seeing a 12v Hookah, say “Wow - how much and how deep can we go?”. My first reaction is: "What do you want to use it for?" Most people on a boat want something that is safe and friendly for their kids and friends to go down a few metres and play about while looking at the fish, etc. Or they are looking for a simple way to get under their boat to give it a clean. This is why we ask what are your intentions/needs. It doesn’t take long for us to ascertain your requirements. We know that the majority of customers are not scuba divers and have no idea about the equipment.
Power Dive Hookahs are made in Australia from quality components, represent excellent value for money and will go on and on for years.
The DECK SNORKEL for instance sells for just under half the cost of an average scuba diving kit.
The DOUBLE DECK SNORKEL sells for $700 less than the cost of an average scuba diving kit, but it’s a setup for two (2) divers.
Don’t forget there are no ongoing costs for tank refills/hydros/annual reg/BCD service for scuba gear.
Simple to operate, they are not ‘heavy’, they are not ‘intimidating’ to novices to snorkelling. It's very easy to keep an eye on the kids as they play around connected to the unit, be it sitting on your boat or the ‘floating’ model that follows the divers wherever they go. These units are quiet and unobtrusive to you or vessels near to you. With fixed hose lengths you know exactly how far and deep you can go, this also means longer and/or multiple dives without actually registering on ‘dive tables’ for any decompression. You can turn the unit on, put your mask and fins on, slip into the water in less than 3 minutes. If you have a spare battery onboard you don’t have to worry about ‘tank refills’ at your closest dive shop, just swap the battery over. The units are small enough to be stowed away on your boat without interfering with your normal onboard gear.
