Thanks to the Independence II for some great wreck diving this weekend. The conditions were so good we weren’t sure we were in New Jersey anymore.

Interested in joining next time? We’ve just updated our website with a variety of classes to get you ready. The best diving of the season is here.

Interested in closing out the summer with a relaxing dive experience led by a seasoned group of Underwater World dive professionals? Confused and concerned by the recent shortage of hot dogs at many of our local Wawa stores?

We may have a solution for you…

On Saturday, August 29th we’ll be hosting our somewhat annual guided dive & BBQ at Lake Hydra. You bring your dive gear, we’ll bring the hotdogs and Divemasters.

Nothing makes diving safer than experience, but, it can be a challenge to get that experience diving locally. Underwater World offers guided local dives with our dive professionals to make sure you have a buddy and get the safe experience that you are looking for. Our Divemasters or Instructors will...

Another weekend has come and gone, but oh what a weekend it was! We want to thank Independence II for hosting us last weekend for a day filled with some gorgeous visibility and a dash of advanced open water certifications. In a first for the shop we combined the fun of Lake Hydra Scuba with the excitement of Jersey diving into one Advanced open water class. Huge congratulations to Aiden Goodson and Kevin Gragg for completing the gauntlet and becoming Advanced open water divers! Mike Golden and Pat McLaughlin threw one exciting class.

Did we catch Mike off guard with this photo? Yes, yes we did. Is Pat second guessing his life choices? Maybe, but we all had a blast!

Daniel Martinez caught some awesome video clips of the conditions and fun stuff to be seen.

Another weeknd down with some less than perfect weather, but non the less Instructor Mike G went out to Lake Hydra Scuba with some students for certification dives! All went well for Kyle and Jawad, a warm congratulations to them on passing their certification dives with flying colors! Kyle was joined by his lovely girlfriend Sabrina, who is also a past Underwater World certified diver.

Always thought about getting your openwater started? We have a couple classes starting soon and what better time than now?!

With another weekend upon us and more students getting out for their Checkouts at Lake Hydra Scuba. These are from last weekend showing off Instructor Mike G with a few of his weekend pool course students. Thank you to the DMs that helped out and kept everything moving smooth in the heat mixed with some showers ( how dare the rain get our gear wet!).

It’s finally outdoor pool season! Last weekend we had a full class of new open water students (Kromer didn’t send us any pictures), and last night was another full pool with three different specialty classes taking advantage of the late June sunsets. Don’t be filled with regret come August, call Nancy at the shop now to find out which classes let you go on the water slide.
