Top 5 Must-Know Rules Before Diving

Diving is one of the best experiences that life could offer. It’s very entertaining that some people even turn it into a hobby. Even though diving is a fun thing to do, let’s not also forget how risky it is for those people who didn’t have proper training and introduction on how to do it properly. People must never, ever, do this if they are not trained by professionals. Professional divers exist for a reason. And that reason is to prepare those people who are fit enough to do this risky activity.


If you are still contemplating whether or not diving is worth the try, we will give you some of the basic rules to check if your body can take the pressure of diving. Also, let this be a list of guide for new divers who will do the activity any day from now.

Always remember, better be ready than sorry. Being knowledgeable can help you enjoy more the activity.

Here are the top 5 must-know rules when diving:

  1. Check Your Gear and Familiarize Equipment

This is the most basic rule in diving. You should always check your gear before doing the activity. Sometimes, when people have been doing diving a lot of time already, they tend to take this rule for granted. Just like what I’ve been telling you, you must always come prepared and ready.

Also, never forget about your buddy check system as you’ll rely on one another for safety underwater. Familiarize all the equipment that you will be using while doing the activity. Those equipment are used because it has a purpose while doing the activity. Stop being lazy and learn the basic equipment. If you fail to do these, then you better think again before doing this risky activity.

  1. Plan Before Diving

Plan everything before doing the activity. And always do the planning with professionals. Planning with professionals or dive masters is different from planning it by yourself. Always be aware of lost-diver protocols, and emergency procedures, as they may differ a bit from one dive site to the next.

If you are planning to do it without a guide, study how to navigate the dive site before the day of the activity, and never forget to list the appropriate equipment that you should bring to avoid accidents.

If you have a diving buddy, always communicate with him/her to make sure you both know what hand signals to use. Take note that hand signals can differ from the location. Always make sure that both of you agreed even to the tiniest information.

Always, or at least try as much as you can to stick to your outlined plan. Make sure to check your gauges frequently during your dive because it’s so easy to lose track of time and find yourself low on air or minutes into decompression. Always monitor your levels to be safe.

  1. You must NEVER hold your breath underwater.

This is the MOST IMPORTANT RULE OF SCUBA DIVING. Holding your breath underwater can lead you to serious injuries, and worst scenario, it can lead you to death. Remember Boyle’s law? The air in your lungs expands during ascent and contracts during descent. Continuous breathing underwater is not a problem because, through it, excess air can escape. But when you do the opposite, you can seriously damage your lungs. Injury to the lungs due to over-pressurization is known as pulmonary barotrauma. We don’t want this fun activity to turn into something terrifying. So always remember, NEVER HOLD YOUR BREATH UNDERWATER.

  1. Dive Comfortably

Dive only when you feel like doing so. After all, it is supposed to be a fun activity. Never pressure yourself to do it when you don’t feel like doing the activity.  Why? Simply because, when you don’t feel like doing what you are doing, your mind might not cooperate well and this might lead to mental and physical confusions which might lead you to accidents. Don’t do it if you are not emotionally, mentally, and physically ready. Always remember, safety first and always dive with limits. If you aren’t up for the challenge, don’t do it. Never hesitate to change your plans if you find that the conditions are unsafe since dive sites can vary dramatically from time to time with regards to water temperature, currents, and surface conditions. Never dive into areas that you are unfamiliar or not comfortable at.

  1. Practice Safe Ascents

As important as breathing, you must always make sure to ascend slowly and safely at all times. Failing to do this can create bubbles that will form in the bloodstream, leading to decompression sickness. A simple way to avoid this is by maintaining a rate of ascent no faster than 30 feet per minute. Those who dive with a computer will have an advantage since they will be warned if they are ascending beyond the normal, while those who are doing it manually, it is important to ascend no faster than their smallest bubble.

According to, fully deflate the BCD before starting your ascent. Don’t use the inflator button to reach the surface. Plus, you must always do a 3-minute safety stop when reaching 15 feet because it helps in decreasing the risks of decompression illness.

Top 5 Safety Tips For Snorkeling

People tend to confuse snorkeling with scuba diving. There is a huge difference between snorkeling and scuba diving. According to, the difference between snorkeling and scuba diving is that scuba diving allows you to go deeper into the water to examine the bed of the sea or lake, equipped with a tight fitting diving suit, and breathing through an oxygen tank. While snorkeling, on the other hand, is a lighter activity than scuba diving. Snorkeling can make you enjoy the underwater more since the main purpose is for you to see what’s in the water, near the water’s surface. It’s meant for you to see the corals, fishes, and other colorful creatures under the water’s surface. Also, unlike from scuba diving, snorkelers don’t deal with heavy equipment compared to scuba diver’s equipment.


To sum it all up, snorkeling is indeed a lighter experience than scuba diving. This makes this activity perfect for beginners. But always remember, even if it’s a lighter activity than scuba diving, you should never take for granted the safety precautions before doing the activity.

If it’s your first time snorkeling, here are some tips that you have to know before doing the activity.


Here are the 5 safety tips for snorkeling:


  1. Proper Introduction About Snorkeling

Yes, ask professionals to tell you what snorkeling really is. It’s true, that through internet we can just learn in an instant what snorkeling really is, but professional snorkelers know this best. Also, they are called professionals for a reason. I know that snorkeling is a lighter activity than scuba diving BUT that doesn’t mean that it is not a risky activity. If you don’t know what you are going into, then you will never understand what you are doing.

It’s so easy to ask professionals, so you don’t have an excuse for not being able to do this. Just make sure that you are actually talking to a professional snorkeler.


  1. Learn The Snorkeling Equipment

Don’t worry, snorkeling is not as complicated as scuba diving, so the equipment will not be as heavy and as complicated as what are used in scuba diving. Again basic rule, know what you are doing and what you are using. It is important that you know the basic equipment that you will be wearing during the activity. If ever accidents are about to happen, knowing the purpose of the equipment can help you avoid those unfortunate circumstances.

Take note of these types of equipment:

   Dive Mask   

   It allows snorkelers to open their eyes under water. It also prevents water from getting into the eyes.


   It is a breathing tube that allows divers to breathe underwater.

   Swimming fins

   It lets snorkelers navigate the water. It makes movement on the water easier and less taxing.


   It keeps snorkelers warm in cold water which makes it not necessary to use in warm water.

   Flotation device

   It acts as a safety device. This is a good device for poor swimmers and beginning snorkelers.


  1. Do It With A Buddy

Do it with a professional or an expert. You just don’t know what might happen during the activity. It is better to have someone with you to help you incase equipment problem might arise, or unexpected events suddenly happen. Anyway, snorkeling is more fun if you are doing it with someone you know, especially with a friend.


  1. Take Note Of The Weather

Weather conditions can vary from time to time. Aside from familiarizing the site, it is also very important that you are aware of the current weather.  Always remmeber that rough water is not ideal for snorkeling and it is significant sign of danger. Beware of th tides because outgoing tides can trap people and other tides can throw the bodies several feet. Also, take note of the wind and rain because it can make open water very choppy and can increase the size and strength of the waves, which heightens the risk of drowning and other injuries. It is ideal for you to stay tune to local weather reports to get necessary information.


  1. Never Touch A Marine Life

Never ever touch anything you see underwater. Aside from it might be illegal in your area to touch marine life, it can also be dangerous to you. Always respect the space of those marine creatures. You are there to watch and enjoy what the underwater has to offer, touching it is not a part of the reason why you are there. Preserve marine life as much as you can.
