One of our passions here at Neptune is the beautiful sport of SCUBA diving. Not only do we carry all the gear you'll need to dive in any location, we also teach scuba lessons to all ages and abilities. Becoming a certified scuba diver is an unforgettable experience and is an opportunity to explore some of the most unique environments on this earth. Our SCUBA instructors here at Neptune, take a hands-on approach to insure educational and fun SCUBA classes.

Learn to Dive From the Best

Neptune has been teaching SCUBA diving since 1973, longer than any other dive school in Tennessee. We take a professional approach to our dive classes rather than conducting them like a "boot camp." You will learn to dive safely while having a great time. Our patient instructors teach at each student's pace and we are confident that you will be pleased with your experience. If any student is unhappy with their course, we will insist on a full refund.

Who Can Scuba Dive?

Almost anyone in good health, who is comfortable in the water can learn to SCUBA dive, providing they are five years or older*. Some of our most enthusiastic divers are well into their golden years. There are certain medical or physical conditions that would not be compatible with safe diving. If someone is interested in diving and has a condition that is questionable, a medical examination by a doctor may be required.

*We have a safe, age appropriate youth program.

Confined Water (Pool) Instruction

After each academic lesson we will proceed to the pool to learn skills required to safely dive. The pool we use is a 15 foot custom built outdoor pool for SCUBA diving. We have an emphasis on your experience, so if you need any extra time developing your skills underwater, our patient instructors are glad to take the time so that you're comfortable. All the gear you need is provided except a mask, fins, snorkel and swimsuit. Neptune uses only state of the art equipment & it is available to our students at 10% off.

Open Water Checkout Dives

After you have mastered all skills necessary in the pool, you are required to complete 4 open water checkout dives. These first few dives are done in just one weekend at a rock quarry typically. We typically take our students to Hokinsville, Kentucky where we dive Penny Royal Dive Resort.  However, we do have access to a few private quarries closer to our shop for some afternoon dives. We even have some classes that prefer to complete the checkout dives on one of our trips to Florida or the Caribbean.

This class is usally run as a camping trip at Penny Royal Dive Resort in Kentucky. For several years now, the awesome staff at Penny Royal have let us camp out and dive over the weekend. Shane, one of our instructors, has the class set up to start on Saturday afternoons around 4:00PM. The class will start with Wreck Diving and Underwater Navagation. Once the sun starts setting, a grill out and picnic starts while we wait for it to get dark. The night dive, most peoples favorite of the weekend, is a great way to end the day before sleeping in our tents. If a hotel is more your style, there are several within a mile from the quarry. The next morning, Shane cooks breakfast for everyone and prepares the group for a morning deep dive. Our last dive is Search and Recovery and is over by 12:00PM on Sunday.
