Remember to Respect Marine Life During Your Dive

Diver and FishAs a diver, there are few things more exciting than having the opportunity to interact closely with the colorful and curious marine life that inhabits our oceans. Coming face to face with aquatic wildlife can be a thrilling and humbling experience, but it’s important to remember that we are just visitors in these creatures’ homes. When divers are careless in their interactions with aquatic species, it can have unintended consequences on their health and well-being. In some cases, it can also put the divers’ safety at risk. But by keeping a few simple guidelines in mind, you can enjoy safe, respectful interactions with marine life during your next dive.

Move slowly and quietly.

You won’t be able to catch much more than fleeting glimpses of marine animals if you’re scaring them off with loud noises and sudden movements. Generally speaking, it’s much easier to observe these creatures when you approach them slowly and quietly. You might even try to remain completely still and let their innate curiosity bring them to you.

Don’t touch or pursue marine life.

Touching and chasing wildlife can not only be very stressful for marine animals, but also promote disease transmission and damage protective coatings on their bodies. If you’re lucky enough to get close to these creatures during your dive, be careful not to touch them or pursue them through their environment.

Be especially mindful of the sea floor.

The bottom of the ocean is occupied by a diverse population of marine animals, including corals, sponges, stingrays and more. Some of these organisms are very fragile and can be easily damaged by contact with humans. Keep your distance from the sea floor whenever possible and avoid disturbing the sediment with your fins.

Don’t take souvenirs back to the surface.

The only things you should ever take back from a dive are photos and trash. Any flora and fauna you find in the ocean should stay there, even if it’s dead. In addition to being irresponsible, removing marine life from the ocean is also illegal in some places.

Keep Your Scuba Skills Sharp With a Refresher Course

Becoming an expert scuba diver takes many years, and dozens of dives. Once mastered, diving is a skill like no other, allowing humans to explore the beauty of the world’s oceans and lakes from a truly unique perspective. It’s why we fell in love with scuba diving, and maybe why you did, too.

But like any practice or trade, scuba is a craft that needs to be refined and improved, no matter how long you’ve been diving. That’s why, here at Horizon Divers, we encourage all of our divers to consider taking a refresher course every so often, to make sure they’re diving to the best of their abilities. In fact, according to the Diving Equipment and Marketing Association (DEMA), there are plenty of divers out there who need a refresher course immediately.

Keep Your Scuba Skills Sharp With a Refresher Course

If you haven’t dived in at least two years, you should seriously consider taking a refresher course before you get back in the water. These classes usually include two components: an online portion, where divers study materials related to diving technique and safety; and a practical portion, where a dive master evaluates a participant for his or her ability to dive proficiently. If you haven’t had a dive in a while, you may be surprised at how many of the basics you’ve forgotten!

Don’t forget that Horizon Divers offers training and refresher courses taught by PADI and SDI-certified dive masters. At more than 100 dive sites, we use the most up-to-date equipment and protocols to ensure that divers are getting all the information and guidance they need. A safe dive is the right dive, and we’ll have you back in the water in no time.

Open Water Diver Certification!

Open Water Diver Certification!

Tips to taking the plunge into the underwater world!

Tip 1:

Determine whether you like scuba diving or not.

  • Have you ever tried scuba diving? If not, consider taking a Discover Scuba course with your local dive center.  The course is designed to give people an opportunity to “try” diving before they commit to the full Open Water certification course. Give it a shot and blow some bubbles!

Tip 2:

Research reputable dive centers.

  • It doesn’t hurt to contact dive centers directly for a quick chat; you can easily find out if they are the type of people you’ll want to spend your money and time with based on the conversation.
  • Check out Trip Advisor!
  • Ask your friends and family!

Scuba Diving Classes in Key Largo, FL

Tip 3:

Determine which route you will take to start your course.  The Open Water Diver course consists of 3 parts; knowledge development, confined water, and 4 open water dives.  To obtain your certification you must meet the standard requirements for each part to “graduate” or what we like to say… become certifiable!

  • Full Open Water Course-
    • This option means that you will do all 3 parts of the course from start-to-finish with your local dive center.  There could be many options that your dive center offers.  For example, maybe they offer the course over multiple weekends or maybe they have a Monday, Wednesday, Friday evening course, etc. Find out what they offer.
  • Open Water Elearning-
    • This option means that you can do the first part of the course; knowledge development, online.  You simply log onto and follow the links for Open Water Eleanring.  Once you’ve completed part 1 online then you simply need to book your confined water and 4 open water dives with a dive center of your choice. This is where researching a reputable dive center comes in handy!

  • Open Water Referral-
    • The Open Water referral suggests that you have already completed part 1 and 2; knowledge development and confined water. Now, all you have to do is contact your reputable dive center to book your 4 open water dives!

As you can see there are many options that hopefully can mesh with our busy lives and get us blowing bubbles in no time!


Judging Weather 101

Judging Weather 101:

Do I make the trip down or do I not?   Is your plan to make the early morning drive down to the dive center for a morning charter out to the reef? What about weather?

First and foremost; check the forecast for the day of diving.  There are many sites you can use to look at this information however, the site that Horizon Divers refers to is the NOAA website. Specifically, the National Data Buoy Center. Refer to Station MLRF1- Molasses Reef, FL for the projected forecast for diving in Key Largo. This site gives you hour to hour wind readings at the Molasses Reef tower. Judging the Weather 101: Key Largo Scuba Diving

The picture above is a screen-shot of what the site looks like on your mobil device.  Notice in the middle of the picture is says “Conditions at MLRF1 as of….”; every hour you will get the wind direction and speed!  As you scroll down on the site you will see the report for each hour from what the winds were doing overnight; also very helpful information when wondering whether it might be the perfect day for you to dive.

Things to look for:

What direction is the wind blowing from?

  • ESE and SE are directions that can make the seas challenging if the wind is blowing strong enough
  • Anything out of the N or W make diving conditions pretty darn good; even if the wind is blowing strong!  Key Largo Diving Services
    Key Largo Scuba Diving Services
    Beautiful day on the water!

How strong is the wind blowing?

  • When you see the word “variable”; that is usually a good sign.  You will see occasionally “variable” winds 5-10 knots; also a great day on the water!
  • 20 knots out of the north is still a decently doable day; expect some chop and maybe 3′ seas generally.  On the other hand, 20 knots out of the SE means much more violent seas; expect 3-5 maybe some 6′ sloppy choppy seas!
  • If you see 20+ out of the SE,  double check with the dive center and see if they will be running their boats!

Note: Most dive shops won’t be able to tell you the night before if the trips will be cancelled the following morning due to wind.  Why? There is still over 12 hours of time from when the shop closes to when the boat leaves in the morning for the weather to calm down considerably!  Those numbers on the NOAA website, specifically those over-night wind numbers, are what we will look at in the morning to judge whether the trip goes.

When in doubt; call the dive shop!  We can at least give you an idea on what conditions are at the present moment and what we expect to see based on the above reports.

Fins up!  ( As Jimmy Buffett would say)

International Coastal Clean-up Day!

International Coastal Clean-Up Day!

Every year the Ocean Conservancy hosts an International Coastal Clean-up day.  Last year alone an astounding 560,000 volunteers in 91 countries picked up more than 16 million pounds of trash!

There are many challanges when it comes to having a clean and safe ocean, but one problem is very simple to understand; trash.

The Ocean Conservancy says, and we all know, that trash in the water:

– Compromises the health of humans, wildlife and the livelihoods that depend on a helthy ocean

International Coastal Clean-up Day

– Threnten tourism and recreation, and the critical dollars they add to our local economies

– Complicates shipping and transportation by causing navigation hazards

If you want to help the oceans and environment then consider volunteering at a location that is hosting a clean-up for the International Coastal Clean-up Day. If you can’t join on a specific date, maybe consider creating your own clean-up with friends and family; and know that you could be saving a life!

Horizon Divers is hosting a clean-up of their own; USCGC Duane Clean-up!

Horizon Divers Coastal Clean-up Project

Join us for our clean-up on September 20th at 12:30pm for a double dip on the wreck of the Duane. The Duane has many creatures that call that wreck home; from sharks, rays and turtles to crabs of all sizes! Last year one of our divers rescued a resident sea turtle who was entangled in fishing line and would have died had he not cut the line!

Let’s make a difference!


Hi again!

Lobsters! Lobsters! Lobsters!

It’s that time of year again! Lobster season is upon us! Between the dates of August 6th and March 31st you can harvest lobster!

Here are some “FUN FACTS” about those deliciously spiny lobsters, complements of the National Park Service.

– Spiny lobsters reproduce in spring and summer. Females carry the bright orange eggs on the underside of the tail until the eggs are ready to hatch.

Lobster Season Information

– Once hatched, the larvae will travel long distances as plankton in currents before settling into shallow water nursery habitats.

Puerulus is the term used to describe the free-swimming phase that moves out of the plankton and into benthic habitats.

– As a spiny lobster grows, it molts, or loses its hard protective exoskeleton (carapace). After molting, the lobster is soft-bodied and very vulnerable to predators for about two days until its new, larger exoskeleton forms over its growing body.

– Spiny lobsters are nocturnal, and emerge from their hiding spots during the night to forage on their favorite foods, including crabs, clams and other invertebrates.

– Spiny lobsters have two large antennae, with are used for fighting and defense, and two smaller antennules, which are sensory organs that can detect chemicals and movement in the water.

Now, after reading how very interesting these underwater crustaceans can be do you still want to harvest them? If yes, then here are some just as interesting and equally important rules and regulations to follow:

Season Dates: August 6th – March 31st

Bag Limit: 6 per person per day

Minimum Size Limit: Carapace larger than 3″, measured in the water
Possession and use of a measuring device is
required at all times

Harvest of lobster is prohibited in John Pennekamp Coral Reef State park, Everglades National Park, Dry Tortugas National Park, no-take areas in the Florida Keys National Marine Sanctuary and in the Biscayne Bay/Card Sound Lobster Sanctuary during both the 2-day sports season and regular season.

Lobster must be landed in whole condition. Separation the thail from the body is prohibited in state waters.

The harvest or possession of egg bearing spiny lobster is prohibited.

What is Sidemount Diving?

What is Sidemount Diving?

Have you ever considered alternative ways to carry your scuba tank underwater? Tanks on your back is NOT a requirement for exploring the underwater world! Crazy huh?!

Sidemount & Recreational Diving in Key Largo, FL

What is it?

Well, it’s just like it sounds; you mount your tanks on your side instead of your back; sidemount! Voila! Sidemount diving is becoming more and more popular with both recreational and technical divers. There is no right or wrong way to your configuration set up, but depending on your goals as a diver you may find it more convenient to dive sidemount.

For example: Maybe you’re considering getting into cave diving; some of those spaces are very tight!  You might be entering and exiting though very narrow passageways… Wearing your tanks on your side makes it much easier to get though whereas you may find it difficult squeezing though with back mounted doubles!

Now, you don’t have to be a technical diver to dive sidemount. Many recreational divers prefer diving sidemount. You might find that you prefer to enter the water without hauling a tank on your back. With shore diving especially, as a sidemount diver, you can simply enter the water, clip them on and go!

For those of you thinking, “I’ve never carried two tanks ever!” don’t worry. You don’t have to. You can mount one tank to your side; it’s called Monkey Diving.

Steve Lewis, who works for Technical Diving International (TDI) wrote a blog titled, Getting Sidemount Tanks To Behave Themselves And Sit Where They Should about sidemount configuration. Check it out! You’ll find some very interesting and helpful information!

There are many advantages to both backmount and sidemount configurations! Think about what goals you have set for yourself as a diver and just know that you have options!
