Another excellent day on the Spectre!

As usual, the Captain and crew took care of us from the moment we stepped on the boat. The Captain found the best possible dive sites given the day's conditions. The crew kept things running smoothly, and jumped to help passengers sometimes before we knew we needed it. And of course the food was as tasty as ever. Another fun day of diving on the Spectre. I will definitely be back!

What’s not to love?

Fantastic outfit. Easy to use website for booking, big + comfortable boat, boat and equipment are in great shape, boat crew are super competent and friendly, the cook somehow conjures up tasty breakfast and lunch from a tiny galley… and the dive sites are beautiful. Go!

Awesome Dive Boat & Crew

Top notch crew and boat! Dive sites were well chosen and effortlessly organized. Dive briefing was full of great and useful information. I will be recommending to all my dive buddies! Hot tub - need I say more?

The diving makes this venue desirable

Always goes to the best available dive locations. Every year when we make the trip out from Colorado to dive from the Spectre the boat always shows upgrades. Very clean, organized, and well managed. Food is delicious with generous portions. Good air fills and ready to dive at each dive site. We saw octopus, sea lion, Seals, and even a Mola Mola. Fantastic trip and a great way to spen three days diving.

Awesome day trip!

Awesome day trip! I'm from NY and really a "Caribbean diver" so I was nervous to try diving in colder water without a dive master leading the dive. If you have those fears, don't worry, you'll love it! The crew was incredible and the boat was very comfortable. I brought my dive gear and just rented a tank, 7m wet suit, hood, and gloves. I really didn't feel cold at all until about 45min into the dive. I made use of the onboard hot tub to warm up in between dives and was fine. The food onboard was also incredible from the home-made breakfast sandwiches to the freshly grilled tri-tip for lunch in true California style. The diving was great and very cool to see the beautiful kept forests. Saw lots of marine life as well. Other divers onboard were super friendly and it was very easy to buddy up since I was solo. Had an awesome dive buddy that was a regular and probably better than if I'd hired a dive guide! He also said these guys are the best dive operators in SoCal. Thanks for an awesome experience, will definitely be back the next time I'm out in Southern California to visit family! Tips: You really don't need a guide; dives are pretty straightforward. Make use of the hot tub in between dives and bring some layers to warm up in between dives if you tend to get cold.
