Underwater Scooter Buyers Guide

What is an underwater scooter?

An underwater scooter is an item of diving equipment which helps a diver to increase their range underwater. When underwater, a diver carries on their back a canister of breathing gas and can only stay underwater for the amount of time which the breathing gas last. An underwater scooter pulls the diver through the water, requiring them to swim less and subsequently uses less breathing gas. The breathing gas will then last longer, and the diver will increase their range underwater.

What to look for when buying an Underwater Scooter?

Speed

The speed which an underwater scooter travels varied from 2 mph to over 5 mph, depending upon the brand and model you purchase. For a beginner, or for family-friendly use, a 2 mph speed should be fast enough, to begin with. The more experienced diver may want a faster underwater scooter, although the faster and more powerful models are a great deal more expensive.

Depth

As an underwater scooter submerges beneath the ocean, the depth which it is able to achieve is also important. A beginner underwater scooter may be able to travel a distance of 15 ft, a considerable distance under the ocean. However, the more expensive models are able to reach at least 100 ft, with some models being able to reach a depth of 230 ft. These depths should only be achieved by very experienced divers, however.

Running Time

It is important to discover what running time each underwater scooter is capable of. For a beginner, a run time of 40 – 50 minutes should be a sufficient amount of time. However, an experienced diver may wish to explore the extreme depths of the ocean and so a run time of up to 120 minutes may be desirable.

Buyers Guide Question

Q: Do I need an underwater scooter in order to go diving?

A: No, you do not need an underwater scooter to go diving. However, an underwater scooter can make your diving experience much more enjoyable and increase your range underwater significantly. An underwater scooter pulls the diver through the water, requiring them to swim less and subsequently uses less breathing gas. The breathing gas in the canister on their back will then last longer, and the diver will increase their range underwater.

Buyers Guide Question

Q: Can a child use an underwater scooter?

A: Most underwater scooters require the user to be 16 years old and above due to the power which the device exerts. Be careful to adhere to these age restrictions as they are set for a reason and some models may be far too powerful for an under 16 years old to use. However, there are models which are suitable for children of certain ages, for example, the JetPilot Sea Doo Dolphin underwater scooter which is suitable for children aged 8 and over. Providing a 2 mph speed and a 15.5 ft depth, the JetPilot Sea Doo Dolphin underwater scooter allows you and your child to enjoy up to 1.5 hours of diving fun.

Expert tip

When you buy a new diving mask, rub some toothpaste on the inside in order to decrease the possibility of fogging. Also, you should not wear sunscreen when you are diving as it can be damaging to coral reefs. Other items are available to protect your skin from the sun, such as a rash vest and a hood.

Did you know?

The first underwater scooters were based on torpedo technology. Their earliest recorded use is through military use as part of World War II.

Dive Knife Buyers Guide

What to look for when buying a dive knife

A dive knife will accompany you through all of your diving and snorkeling adventures. It may also be the only thing that you can save you if you encounter trouble within the ocean depths. Whether you get entangled or see an ocean creature imprisoned within a fishing net, having something that can help is priceless.

Stainless Steel

Possibly the most important thing when buying a dive knife is ensuring that the blade steel is stainless. As well as any other steel accessories that may be located on the knife. This will ensure that your knife doesn’t rust and get weakened. You should still, however, ensure to rinse the knife with clean tap water before putting it back into its sheath. This will prevent any of the potential saltwater getting lodged within the crevices.

Sharp vs. Blunt

The reason a lot of divers use a blunt knife is that you don’t need to pay so much attention to injuring your gear. With a sharp tip knife, you may accidentally cut your hose or suit. Both have their uses, and in essence, it’s good to have both. Most divers have the blunt knife mounted on their forearm for easy general use, and the sharp tip around their ankle. The sharp tip only being used in a real case of emergency.

Sheath & Straps

Most dive knives nowadays come with a sheath and a strap so that you can mount it on your forearm or leg from the get-go. This is a great convenience, and you rarely have to go out and search for these things yourself. When diving, having a reliable knife is almost as important as having a sturdy sheath. After all, what can you do if your straps get loose or unlock and you end up losing your knife?

Conclusion

Now that you have a grasp of the basics, you can go and search for your ideal dive knife. Remember, you should feel comfortable when handling it; a good knife is like an extension of a diver’s arm!

Expert Tip

When diving, make sure to strap the dive knife somewhere where you know you can heavy easy access to it. Too often do beginners strap the knives somewhere where it’s impossible to reach them, and get themselves in unfortunate situations because of this.

It can be a daunting task for a beginner scuba diver to wrap their head around all the essential equipment that is needed for a successful, safe dive. It doesn’t need to be. Each item of kit plays an important role, and after your first dive, you will see in action how each piece of equipment is important and why.

But before you set out on your first dive, then read this guide, as it will explain the functions of the most essential pieces of diving equipment.

Exposure Suit

An exposure suit is worn to regulate your body temperature while you are underwater. It is essential for every scuba diver.

A wetsuit is the most common form of exposure suit. It is a skin-tight suit that is usually made from closed-cell foam neoprene. It offers you insulation while you’re underwater. The thicker the material the wetsuit is constructed from, the more insulation you will get, so thin wetsuits are for warmer waters, and thick ones are for tepid or cold water.

A drysuit is slightly different. These are designed for extremely cold waters. As the name suggests, you are kept completely dry, because air is used for insulation, rather than water, which it is with a wetsuit. This means that drysuits are looser than wetsuits, which also allows for more layers to be worn underneath them

Dive Mask

The primary function of the dive mask and the most important is that it allows the scuba diver to see while underwater. They come in a variety of shapes and sizes, with some offering panoramic views, and others offering more limited views, but then being less cumbersome.

The two most common types of diving masks are the half mask and the full mask.

The half mask is similar to a pair of goggles. They go around the head and cover both the eyes and nose, but they do not cover the mouth.

A full mask covers the whole of the face. This means that that the breathing apparatus must be integrated into the mask. A full mask is far more common in scuba diving.

Fins

Worn on your feet, fins increase your potential for efficiency and speed when kicking, which is due to their huge surface area, and other features such as vents. The reason why divers wear them is that it means that you can move through the water purely by the use of your feet, therefore it frees up your upper body completely.

Diving Tank

Without your diving tank, you’d only be able to be under the water for as long as your lungs can handle. Which wouldn’t be very long at all? The diving tank contains the essential compressed air or gas mixtures that you will breathe while diving.

Regulator

The other part of your breathing apparatus, besides the diving tank, is the regulator. This screws into the diving tank. And it also will go into your mouth or connect to your full-face dive mask. Its purpose is simply to reduce the pressure of the gas in your tank to ambient pressure which you are then able to breathe.

Dive Computer

Dive computers come in a huge range of sizes, shapes, and offer lots of functions. But their main purpose is to monitor and measure the time and depth of your dive. This then means that it can warn you or advise you as to the ideal ascent rate and if you missed any decompression stops. Some dive computers will also monitor the levels of gas in your tanks. Many can be worn on the wrist, like a watch.

Pressure Gauge

This piece of equipment has a single purpose which is to tell you how much gas you have in your diving tank. This knowledge is extremely important so that you’re able to regulate breathing and plan your ascent.

Depth Gauge

This is another simple piece of equipment that has one purpose, which is to gauge your depth, therefore telling you what depth you are at while you are underwater, and it will also show you your maximum depth.

Buoyancy Control Device

The buoyancy control device – also known as BCD – is worn by a diver to make sure that neutral buoyancy is established. This basically means that it stops you from sinking to the ocean bed or floating back up to the surface of the water. It is manually operated and requires a lot of attention.

Snorkel

A snorkel is a tube that is usually made from plastic or rubber. One end is put into the diver’s mouth, while the other should be above the surface of the water, therefore allowing the diver to breathe. Scuba divers use these when near the surface so that air in the diving tank can be reserved for greater depths.

Dive Knife

A dive knife is a knife with a serrated edge and is usually made from stainless steel or titanium. It offers divers security underwater, so if they become entangled in a fishing net, for example, they can cut themselves free.

Surface Signaling Device

There is a range of signaling devices available, such as lights, whistles, and air horns. These are basically used to attract attention if the diver is at the surface and needs help.

Now you know all the most important pieces of equipment for scuba diving. After your first dive, you will quickly become acquainted them. I hope you enjoy your scuba diving adventures!

Snorkeling and diving are two very enjoyable water sports that allow you to see the beauty of the underwater world, while also offering your body great exercise, but they can be dangerous too, so read this guide, and then you’ll know how to stay safe when snorkeling and diving.

Are Snorkelling and Diving Right for You?

Both snorkeling and diving appeal to people of all ages and sizes, but before you think about strapping on a snorkel face mask and putting a scuba regulator in your mouth, you need to think carefully about whether you are going to be capable of snorkeling or diving.

You don’t need to be Michael Phelps to go snorkeling, of course, but you must be in relatively good physical shape and also you should be a confident swimmer too. Your body should also be in good working order too, so if you have been seriously ill recently or suffered a major injury, then consider waiting until you’re fully recovered before you take the plunge.

Research Before You Dive

It’s a good idea for any budding snorkeller or diver to do some research before getting into the water.

For snorkellers, this will include acquainting yourself with what equipment you should buy to wear during your snorkeling, and it also will be choosing a place to snorkel where the water isn’t too cold, and where you know there aren’t any major hazards, such as big, unpredictable waves.

For divers, you will need to receive training prior to your first dive. Therefore, it is important to choose a dive school that has a good reputation. A bad teacher can leave you in danger, so making sure you’re learning from an experienced, trustworthy instructor will help to keep you safe.

You can prepare for the training by learning about the essential diving equipment you need for a dive, and what role they play in keeping you safe. Once you’re on the diving course, then do not be afraid to ask your instructor lots of questions. The more information that you have when you’re underwater, the safer you’ll be.

Prepare your Body

The two most important things that you can do at home prior to snorkeling or diving is to start swimming more regularly so that the muscles you’ll be using while snorkeling or diving will be less likely to tire easily, which could put you in danger. You should also spend some time doing breathing exercises too.

When it comes to diving, you have to be able to breathe calmly, regularly, and deeply at all times. A short breath or holding your breath can cause dire consequences, so some practicing of the right breathing methods will keep you safe.

Plan Your Dive

Every experienced diver will tell you that you must plan every single dive thoroughly. What does this mean? You need to know what the maximum amount of time for the dive is, and you also need to know the maximum depth. On top of this, you should have knowledge of how to navigate the dive, if you’re not diving with a guide.

Always Dive or Snorkel with a Partner

You should never consider diving alone. Safety comes in number, and the magic number for snorkeling and diving is two. You need to have a buddy. Prior to diving, make sure that you have agreed what signals you will use, as these sometimes differ in certain places in the world, and, actually, it is possible that the same symbol might mean something different to your partner.

Plan your route with your buddy, and also make sure that you have discussed what will happen in case of emergencies. You both need to have a plan for what you will do if you are in danger.

How to Avoid Decompression Sickness

Before you even consider putting your diving gear on, you must make sure that you’re fully hydrated. And that hydration cannot be through alcohol. You should never consider putting yourself at danger by drinking alcohol before a dive. Good hydration is an important element of avoiding DCS.

A safe ascent means a safe dive, so do not ascend at a rate more than 10m per minute.

You should also make sure that you don’t over dive. Each day limit your number of dives to three at the very most. And you should never dive more than three days in a row. A rest day is imperative after either two- or three-days diving in a row.

After you dive, don’t get on an airplane or ascend to a high altitude for at least 24-hours afterward.

What to do in Case of Emergency

Don’t panic. Focus on your breath. Remember your training.

These are the three most important rules for what you need to do in emergencies. If you panic, you will either breathe shorter breaths, which will use up your oxygen quicker, or you may even stop breathing. That’s why you should focus on your breath. If you hold your breath, then you’re putting yourself in huge danger.

Keep calm, and take deep, long breaths, and then remember what you were taught in your training. You should have been prepared for all eventualities, so now is the time to use that training.

Don’t Stray Too Far from The Shore

Snorkellers can find themselves so focused on the beautiful underwater delights that they don’t take notice of how far from the shore they have swum. Check regularly where you are, as if you swim too far from the coast, you could find yourself in choppier waters or even surround by sharks.
