Best place to rent hands down! I got there, they knew exactly who i was, what i had reserved, they even laid it out nicely and had everything ready to go. they go the extra mile and double check all your gear and make sure you have enough weight. great friendly people and the service is incredible!!

Perfect! My buddy and I haven’t dive for a year. We did a refresher course today. We reviewed all the things and then dive for 3mins. The water was cold so we wear 7mm wetsuit. All the gears were clean. We will come next time!

Dave was such a friendly and helpful guide! I did the refresher dive after being out of the water for two years. Before our dive he walked us through what we would be doing and provided helpful tips to ensure a safe and enjoyable dive. He's a great teacher... I'm pretty sure I learned more in that short recap than I did from my cert! I finally mastered my buoyancy and felt full comfort in the water thanks to Dave. He said he has done thousands of dives over the course of his career and it shows. Would highly recommend!

#1 tour on Catalina Island for a reason! If you want to experience awesome sea life, with a great team of folks to work with, this is the tour for you! Dave and his crew are awesome! From the beginning of the dive to the end of the dive I felt taken care of and had no worries whatsoever! The gear is great, the people are great, and the dive park is great! If you have been diving for years, or if this is your first dive, Diving Catalina is the place for you!

Completed my advanced OW with them and my brother completed his OW & AOW. These guys are amazing so down to earth and go the extra mile to make sure you are comfy and confident, Rane & Lisa were incredible to us and made the experience so easy and comfortable, Super knowledgeable and kind. Even brought my buddies back here to certify as new OW divers. Highly Recommend them!

Dave was a super knowledgeable and friendly dive instructor. I visited Catalina to finish up some open water dives for my diving license. Dave was flexible with a tricky weather situation, and I felt like I learned a ton during our time together. He's been on many many dives before and his experience shows through. Highly recommend!
