Does a Dive Master go down with me? Is a Dive Master provided?


Dive Masters NOT Provided: Our Dive Master DOES NOT enter the water with you. It is industry standard and USCG orders in San Diego that our Dive Master must remain on board the vessel, except in the event of an emergency/urgency on the surface. If you would like a Dive Master, please select "Hire a DM" on our registration page. You must select this option at least 72 hours in advance of your trip, longer for weekday trips.




What should I bring?


You will reap the benefits from our years of experience, IF you bring the following along with your dive gear, of course. Do not underestimate the importance of being able to get warm and dry. (NO, your "HOT" buddy’s (or boat crew’s) body-heat is not what we are talking about!). The water temperature is between 50-52 degrees; with multiple dives, getting warm between them will make your day that much more AWESOME! ➢ Exposure Suit: 7mm wetsuit or drysuit ➢ Dive gear (unless you are renting) ➢ Sunscreen ➢ Dry Towels ➢ Dry Clothes ➢ Sweatshirt or jacket to keep warm ➢ Seasickness Medication ➢ Government Issued ID ➢ Certification Card ➢ Tip for the Crew Trust me; if you have ANY thoughts of seasickness, you may want to try some seasickness medication (JUST DO IT!), such as Dramamine, Bonine or even Ginger. Seasickness can ruin your dive trip (and everybody else’s) so please do your body a favor and come prepared. Dramamine comes in a "less drowsy" formula, and Bonine is a less drowsy formula, (in my humble opinion) regular strength Dramamine sometimes makes a lot of people too sleepy to think right the day of, better to take this one the night before. We (as in the UNIVERSE) have found the most effective way to ward off seasickness is by taking the recommended dose the night before, then again 2 hours before the trip. But of course….it’s your call.;)

Do I need a Buddy? Can I dive solo?


You do not need to sign up with a buddy. If you want a buddy, we will do our best the day of the trip to pair you up with another diver or group of divers. :) You are welcome to dive solo, as long as you are honestly comfortable diving alone. We do prefer you have a redundant system.




What is the site description of the NOSC Tower?


NOSC TOWER - Depth ~ 60ft The NOSC Tower was a weather and lab station that was built in 1959 and lasted until a storm in January 1988 knocked her over. Her labs that once stuck some 50 feet above the water were simply gone. She twisted as she fell and broke into pieces, scattering debris. The pilings that supported the structure have been under water since 1959 and are covered in life. The fallen structure is littered with invertebrates and some of the largest Cowries we have ever seen. It is a great place to practice penetration skills. While there is no actual enclosed environment, the maze-like structure allows you to weave in and out of it.




What is the site description of the Connors Canyon?


CONNORS CANYON - DEPTH 45-75ft Connors Canyon a beautiful pinnacle dive in our rebounding kelp forests covered in fish life, eels, and quite often a Giant Black Seabass:

A large 45' pinnacle nestled in about 75' of water in the Point Loma kelp forests. The south end has a sheer cliff that begins at the seafloor running all the way to the top of the pinnacle. We often see a 5' giant black seabass hanging around the top of the pinnacle. The pinnacle itself is a table-top of rocks and boulders teaming with schooling fish and surrounded by canyons that channel out in numerous directions. With overhands, endless nooks and crannies, and abundant sea life this is a fantastic dive location. (Description by Dive Master Chris)




What is the site description of the Ingraham Street Bridge?


INGRAHAM STREET BRIDGE - Depth ~ 60ft The former Ingraham Street Bridge was demolished and sunk in wreck alley as an artificial reef. The cement pillars house fields of all four types of Gorgonians (sea fans) found in Southern California waters. These are a rare find in our local waters and well worth the dive. We have seen many eels, octopus, and of course, reef fishes hanging around this beautiful artificial reef.




What is the site description of the HMCS Yukon?


The HMCS Yukon is a 366' Canadian Mackenzie class Destroyer. She was sunk in Wreck Alley off of Mission Beach, San Diego CA. Divers from all over the world come to dive the Yukon. Sunk as an artificial reef in June of 2000, the HMCS Yukon rests in about 100’ of water with her deck between 65'-75’. She sank without warning, just before the planned sinking was to occur. Her unplanned descent to the sea floor landed her on the port side. Large cutouts initially, set up for divers to penetrate safely, have created some interesting and challenging penetration. The HMCS Yukon is an advanced dive, therefore, penetration is not recommended unless you are trained and certified to do so. The HMCS Yukon takes many dives to become well acquainted with her layout and structure. Sea life is abundant on this wreck, blanketed with large white plume sea anemones called Metridiums (pictured right). On the wreck, you may encounter sea lions, harbor seals, rockfish, and several species of perch, and bass. She also has rockfish, ling cod, large sheep crabs, thorny sea cucumbers, and much more hidden among her structure. As you descend you will see the characteristic black smith and señorita fish. One thing is for sure...you will not be disappointed scuba diving the HCMS Yukon.




What is the site description of the Ruby E?


The morning of July 18th, 1989 marked the day when the Ruby E, a 166' United States Coast Guard Cutter, would begin her new life as an artificial reef. Built during the prohibition, she served the U.S. Coast Guard for many years. Once decommissioned, she was sold and used as a commercial fishing vessel, and eventually as a drug runner. Ironically, she was confiscated by the U.S. Coast Guard, only to sell her again at auction. She sat derelict for several years until the owner allowed her to be sunk as the second artificial reef in Wreck Alley. The Ruby E sank without explosives, and remarkably landed upright in the sand. She is intact and is completely covered with anemones and marine life. Although fragile, she offers some amazing opportunities for beginning penetration and wonderful sea life.




What is the site description of the Horse Head Reef?


HORSE HEAD REEF - Depth ~40-60ft Horse Head Reef is another shallow favorite. This rocky reef is shaped like a horses head, hence the name. The long structure is full of lobster, Garibaldi, Opaleye, and a lot of awesome invertebrates.




What is the site description of the New Hope Rock?


NEW HOPE ROCK - DEPTH: ~20-30ft One of the shallowest dives in the Point Loma kelp forests, this is a great spot for beginners, open water classes, and people new to California diving. New Hope Rock exhibits large boulders, abundant sea life, and waters that lack a thermocline;). Garibaldi, Opal-Eye, giant kelpfish, calico bass, sheep head, are some of the fish life you will see. You will also see several invertebrates such as lobster, urchins, sea stars, nudibranchs, and octopi.




What is the site description of the Donut Hole?


DONUT HOLE - DEPTH: ~25-35ft The reef structure on this site is varied, so much so, that it is easy to find your way back without help! The site is named "Donut hole" because the reef has a large round rock with a hole straight through the middle of it and shaped like a donut. Situated within the Point Loma kelp beds, this shallow site houses several animals you could expect to see in the intertidal zone. The rocky reef provides protection and shelter for lobster, urchins, sea stars, nudibranchs, and octopi. Make sure to peek into the crevices and look carefully to find the hidden life. The kelp forest is also home to the giant kelpfish, calico bass, mollusks, sea stars.




What is the site description of the El Rey?


EL REY - KELP CUTTER After 35 years of service as kelp harvester for Kelco, this 100’ by 32’ vessel was donated to San Diego’s newly developed artificial reefs program. Once she was made safe for divers she was sunk as an artificial reef in April of 1987. After nearly three decades on the ocean floor, her wooden hull and parts of her superstructure have collapsed but she has gained a large population of strawberry anemones along with metridiums, gorgonians, sea star, nudibranchs, and of course fish populations. El Rey Max Depth: ~85'​




What is the typical Visibility in San Diego?


Visibility can range greatly from day to day. During the late winter, spring and early summer months, we experience visibility from 5-30ft. During the late summer, fall, and early winter the visibility clears up and is often 40-100ft!




Do you take divers to the Coronado Islands in Mexico?


Unfortunately, we no longer make runs to the Coronado Islands. It is a long trip, and in recent years the Mexican Government has turned many boats around and sent them home as soon as they cross the border. Several years ago, they closed the border entirely since they have opened it up, it has remained unstable. They also have implemented a tourist permit that costs $30 per person in addition to the cost of the trip. Although it seems to be getting more stable as time goes on, the risk of driving there only to be turned around is still too much.




Will I see Kelp on all of the dives listed as "Kelp Forest" Dives?


After the El Niño year hit in 2016, the beautiful and thick Giant Kelp Forests have diminished significantely. Many of our sites that were once thick with Giant Kelp, are now rocky reefs with some kelp stalks. They still house beautiful sea life and are wonderful sites, but may not have the amount of Kelp they once had. We are hopeful that the water will cool down and the Kelp will grow back :)




Do I need an Advanced Certificate?


We ask that divers only plan dives where they can maintain a depth/difficulty level to which they are certified.
