 This trip to the Deep Hole area focuses on photography and hunting while drift diving.   

Having an SMB and knowing how to use it is required and of utmost importance. The Deep Hole/Neptune’s/County Line area is about 20 miles south of Ventura Harbor (15 from Channel Islands Harbor) with the main dive sites ½-1 mile offshore and some deeper sites extending further out. Another name for the Deep Hole area is the “depot” because, supposedly, it was created using concrete rubble from an old railroad depot. 

 This area is large and dramatic, comprising large boulders, small rock piles, rock walls, rocky reefs, and pinnacles. There are deeper sites (70′-80′) such as Sea Fans and Sweet Spot, and there is a shallower (40’-60’) spot called “The Ring” with its rocky reef and kelp forest that can rival any spot on the islands on a good day along with an awesome site very close to the ring called “Towers”. The main dive area has depths ranging from 40′ to 100’, and other unexplored areas are out towards 150′ and beyond! Depending on the time of year, the visibility can be from 10’-50’. 

 The Neptune’s area can be excellent for photography, spearfishing and lobster diving. There is sheepshead and lots of large barred sand bass swimming around the rocky reefs, kelp (not as much out deeper), scallops, lobsters, and lots of invertebrates, so you can see why this area can be so special and without the diving pressure, the islands get. This area is more like what California diving used to be! 

  Advanced divers and above that have experience in cold water conditions including; current, swell, possible limited visibility and deep water. Most importantly, good buoyancy control is needed. An SMB or surface signal tubes are required, and knowing how to use it is of utmost importance.

 The DV Triton is 40′ x 12′ in size and set up for only six divers. It’s a new-to-dive trips around the Channel Islands, local wrecks, and awesome coastal diving, and gives divers choices they never had before. The owner of the DV Triton, Danny Graham, has been diving for years as a recreational, Tech and rebreather diver. A few years back, he went from working for Nuvair to owning a boat doing commercial urchin diving and removing old nets and lobster cages. Mid 2023 Danny received his captain’s license and license to operate the boat for six divers. Now, Danny can operate the boat for a multitude of work and keep doing what he loves.  If you are an Experienced Advanced Diver or above and are looking for something different than the usual diving, the DV Triton is for you. 

 Where the Triton lacks creature comforts, it makes up for it with speed, tank fills, and the ability to do things and dive locations you can not with other dive operators. For tank fills, there is a 3500 PSI compressor with banked 35% Nitrox and the ability to do custom Nitrox mixes and supply 100% 02. It is best to bring your tank full for the first dive, and then for the second and third dives, you can get Nitrox fills for free. Read more about the DV Triton HERE.
