General Info

Dive Experience for Cocos & Malpelo
Cocos Island presents the same diving challenges as any other Pacific, Indian or Red Sea diving location. Cocos, however, is not recommended for inexperienced divers because it is an open ocean destination that requires advanced open water diving skills.

Please note, the minimum required level of certification to dive at Cocos is Open Water with the additional Specialties of Deep & Night Diver. We also recommend having a minimum of 25 hours of diving experience.

Most dives are at depths deeper than 60 feet / 18 meters. At Cocos currents and visibility can be entirely different in just a few hours. Please note, the dive guide will always be the final authority as to whether a passenger can do any specific dive.

Malpelo Island can offer more challenging conditions. Please note, at this time we are not scheduling regular trips to Malpelo.
Dive Conditions
Most of the action is at 60-90 feet /18-27 meters, and most dives are between 60-130 feet / 18-40 meters. The safety limit is set at 130 feet / 40 meters and a dive computer is necessary. Visibility averages 60-100ft/18-30m.
Water Temperature
Average temperature is 79 F to 84 F (26 C to 29 C), although it can be a few degrees lower under the occasional thermocline.

Please note Malpelo can have significantly cooler temperatures.
Certification
All divers must bring proof of certification by a national certifying agency. The certification must allow the diver to dive to the recreational dive limit of 130 feet (40 meters). The Dive Master will request to see your certification before you are allowed to dive. If you are certified for Nitrox and rebreathers as well, then remember to also bring those certifications.
Nitrox
To increase safety and bottom time while maintaining safe non-decompression dives the use of Nitrox is recommended. The vessel offers full onboard TDI training in Nitrox, with rental of Nitrox computers. Nitrox fills are free for Nitrox certified divers.
Rebreathers
Please check directly with our office if you are bringing a rebreather with you. We can supply you with tanks, scrubber material and any further assistance you need, and can provide you with the costs of these items.

Please note, at this time we are no longer teaching the rebreather course and we do not have any units available to rent. Check for further rebreather information on this website at PRICES & SCHEDULES - Rental Gear
The Crossings
When all passengers are boarded, the vessel will take 32-36 hours to reach Cocos Island (check specific itinerary of Malpelo/Cocos trips for further details on those trips). Crossings are normally calm, but to prevent motion sickness we advise you to take the necessary precautions. At the conclusion of your trip, we will return to Puntarenas where a bus will be waiting to return you to your San Jose hotel.
Gear to Bring With You
You will need the following gear: 3-5 mm (1/8" to 3/16") wetsuit, mask, fins, snorkel, regulator with visible pressure gauge, a mandatory dive computer, buoyancy compensator, depth gauge, dive gloves, weight belt (without weights), dive light, and dive watch. It is recommended that you mark each piece of gear with waterproof paint or tape. We suggest you put all or most of the above items in a carry-on bag. There is ample storage space for your diving equipment, including your own personal locker.
Equipment Provided Onboard
We provide you with weights for your weight belt: 2, 3, 4, and 6 lbs. (1, 1.5, 2 and 3 kilos). We also provide you with air or Nitrox tanks -- 80 cubic ft. aluminum (12 liters).

Please note, our tanks are standard yoke (INT), not DIN. Please notify our offices in advance if you need an adaptor.
Rental Equipment Onboard
You can rent a complete line of ScubaPro dive gear: BCD, regulator, wetsuit, mask, fins, snorkel, and Aladin Nitrox dive computers.

We have a limited supply of 15 Liter steel tanks. If you would like to rent one, make sure to reserve it well ahead of time.
Meals & Beverages
The menu aboard offers a delicious combination of American and local cuisine. Meals are varied and well balanced, and we also offer delicious snacks between dives. Food is abundant with plenty of fresh tropical fruit and salads and is served buffet style. Please let us know of any special dietary needs or requests, but try to be lenient, as storage and preparation space is limited.

Soft drinks: Free, Bottle of wine: $15 - $35.

Hard liquor is not available on board but our guests are welcome to bring their own, which should be purchased prior to boarding.
Clothing
We recommend casual and cool cotton attire while on board. Nights can be chilly and/or drizzly so bringing a sweater, light jacket or windbreaker is recommended. In San Jose dress is slightly more conservative, like long jeans and collared shirts. For women, we recommend holding off wearing shorts and beach type clothing till you are aboard the vessel. We suggest packing in a soft duffel bag for easy luggage storage. Booties or hiking shoes are recommended if you want to visit the island.
Visiting the Island
We will usually make one or two visits to the island itself during a trip.
Crew
The Undersea Hunter, Argo, and Sea Hunter crews consist of a unique combination of talents, offering the ultimate in service. The Undersea Hunter has a crew of seven, while the Sea Hunter and the Argo have a crew of eight. The dive masters, deck hands, and skiff drivers make sure you have the best possible diving adventure, while the chef and steward prepare delicious meals and take care of all your needs on board.
Communication Onboard
The vessels maintain constant radio contact in the event of any emergency. Your family and friends can contact our office at telephone: +506-2228-6535. We are happy to let family and friends know how you are when they call our office.

Our main office is open 8.00 - 17.00 Monday - Friday (except for national holidays). Outside of those hours our emergency contact number is +506-8813-5656.

Please understand, however, that you will be in a remote area and it is preferable that personal communications to the boat be limited to emergency use only. We also now keep a satellite phone on board, which costs $3.50 per minute.

Cocos Island is now equipped with a cellular phone tower, as well as a public phone. When in closer proximity to the Island at certain locations (assuming your cell phone works in Costa Rica), it is possible to use your cellular phone services, but keep in mind, it is still an international call.
Electricity
The vessels have both 110 and 220 volts ac. The cabins have 110 volts ac only.

The vessels have standard US and European sockets (but not British style sockets).
Entertainment
There is a variety of nightly entertainment available on board: slide shows, DVDs, music, games and much more. Please feel free to bring along your favorites.
Tips
Since it is customary to tip crew members, many people ask us what tip amount is appropriate. This is a very personal decision, as tips are your way of expressing satisfaction. Generally the tip is given to the captain who distributes it equally amongst the crew. Please note that we do not dictate or include tips.
Medical Support On-board
We have a well-equipped first aid kit including oxygen on-board. You should bring anti-seasickness medicine and ear drops if you feel you will need them.

Please inform us and especially the dive guides if you are taking medication or suffer from allergies.
