Costa Rica Liveaboard Cocos IslandThe newest boat is the Argo, an intentional blend of working ship and luxury yacht. The 130 foot vessel was redesigned in 2008 to accommodate 16 discerning passengers in 8 well-appointed staterooms as well as provide a stable platform for a deep-diving submersible and for remote operating vehicle deployment (R.O.V.).

Argo is equipped with three, powerful 24 foot skiffs that provide the ability to perform submersible tracking duties and can take divers rapidly to any dive site within an extended, safe radius of the mothership.

Argo Facts

Deep Sea SubmersibleCosta Rica Submersible

The Deep Sea is a custom-build one-atmosphere submarine, capable of carrying a pilot and two passengers to a depth of 450 metres / 1,500 feet. The view from DeepSee’s acrylic sphere is unparalleled, with a 360-degree field of vision. The 4-inch thick acrylic sphere actually disappears when immersed, giving the astonishing sensation of total freedom and the sub blends well into the environment such that the marine life largely ignores her. This allows you to get up-close and personal with the creatures just outside the cockpit. DeepSee handles and performs with much agility,      navigating or hovering with precision just a few feet above the rocks and corals while causing no disturbance to the marine environment.

DeepSee’s operational mission is to collect data and capture live images of the diverse life forms in the deep ocean. To accomplish this, she is equipped with a high definition video camera, digital still cameras and an impressive array of HID lights. DeepSee also boasts a fully articulated, manipulator arm for collecting samples or retrieving scientific instruments. Passengers are welcome to also use their own video and still cameras through the subs optically-corrected, acrylic sphere and will receive a souvenir DVD (videos and images of prior encounters from some of DeepSee's early dives).

The Undersea Hunter Group offers this singular experience to the world of the adventure traveler; a journey deep into the submerged realm where few have gone before.

DeepSee Dive Sites

A unique seamount teaming with marine life. The base of Everest starts at 100 metres and the peak rises to 50 metres. Everest is still fed by sun light and hence is very rich with corals, reef fish, rays, and sharks. During the dive, schooling hammerhead sharks, mobula rays, silky sharks, and big tuna fish cruising around the seamount are often observed. A family of large groupers often greets DeepSee. Depth: 100 metres 
Dive Duration: ~ 1.5 hours

The Wall
Head into the darkness and explore sheer vertical sections of the wall, as well as ledges, overhangs and steep sandy slopes. The fish, corals and fauna are unique and adapted to life in complete darkness. Exciting species of fishes such as the ancient-looking jello-nose fish (Guentherus altivela), the goosefish, and a few unidentified species can be seen. Sighting an almost mythical deep-water shark known as the prickly shark (Achinorhinus cookie) is a highlight. Depth: 300 - 450 metres Dive Duration: 2.5 - 3.0 hours
