Trying Scuba in Guanacaste: What a Discover Dive Really Is

Here is a fact that makes no sense until it does. In Guanacaste, an introductory dive for someone who has never breathed underwater costs more than a two-tank dive for a certified diver. Not a little more — from $195 or $223 against $162.

You are not paying for more diving. You are paying for an instructor whose entire job for that morning is you.

An introductory dive goes by several names: discover scuba, try dive, basic diver. They all mean the same shape of day. You get a briefing on land or on the boat, you are fitted with gear, you learn a handful of skills, and then you go underwater with an instructor beside you for the whole dive.

The word it is not is certification. The Catalina Islands operator states it outright in its own listing: the programme “is geared for people who want to try scuba diving for the first time and do not hold a qualification already. You will not receive a PADI certification.”

A certified two-tank trip at the Catalinas runs from $162, and a certified fun dive from $165. The introductory dives run from $195 in Tamarindo and $223 at the Catalinas.

The difference is supervision. A certified diver goes down with a guide leading a group. A first-timer goes down with an instructor who stays within arm’s reach and is not looking after anyone else. That ratio is the product, and it is the reason the price is inverted. It is worth understanding rather than resenting — if the introductory dive were cheap, something about the ratio would have to give.

The Tamarindo try-dive listing says travellers “will have to fill out a medical questionnaire prior to the experience”, and that they should have “at least a moderate level of physical fitness”. The Catalinas programme lists itself as “suitable for all physical fitness levels” and requires that children be accompanied by an adult.

The questionnaire is standard across the industry and it is not a formality. Asthma, recent surgery, heart conditions, ear problems, pregnancy and some medications can all require a doctor’s sign-off before you are allowed in the water. Getting that sign-off is not usually possible on holiday at short notice.

Introductory dives here are shallow and supervised, which shapes the marine life you get. Expect schooling fish, rays on the sand, eels in the rock, and the volcanic structure that defines diving on this coast. This is the eastern Pacific — the interest is in fish volume and rock, not coral gardens.

What you should not expect is the thing the Catalinas are famous for. Oceanic mantas are there from November to April, but they are deep, and encountering them is a certified-diver proposition. Even for divers, the Playas del Coco dive centre is careful: “Manta ray sightings are not guaranteed, as they are wild, pelagic animals.” It also notes, for anyone nervous about the idea, that “manta rays are gentle, filter-feeding animals and pose no danger to divers.”

The clearest water comes in the dry season, December through April. So does the wind: the Papagayo winds “occur mainly between December and April, when cold air masses from North America move south and are funneled through mountain gaps near Nicaragua.”

For a first dive that argues strongly for a morning departure, when the sea is usually calmest, and for booking early in your trip rather than on the last day — so that a weather cancellation leaves room to try again.
