Silent Divers Chaweng: PADI 5 Star IDC, Sail Rock 4,650 THB

Overview

Silent Divers is a PADI dive centre on Chaweng Beach Road, Koh Samui, about 0.6 km from central Chaweng in a straight line. It sells PADI courses and guided two-dive speedboat days to Sail Rock, Koh Tao and Chumphon Pinnacle. As of October 2026 the operator advertises Sail Rock days from 4,650 THB (~133 USD) and the shop opens daily 11:00-19:00.

The reason to pick it is the training credentials: PADI’s register lists the centre as a 5 Star IDC with 10 instructors, in English, French, German, Spanish and other languages. The main caveat is the schedule. Each destination runs on fixed weekdays, trips fill a whole day, and the operator itself warns that November sea conditions are difficult.

Key Facts

Silent Divers teaches PADI courses from a first try-dive to the Open Water certificate. The Open Water package costs 18,200 THB (~520 USD) and includes eLearning, pool training, four sea dives, equipment, certification, transfers and lunch, according to the operator’s own site in October 2026.

Discover Scuba Diving starts from 5,850 THB (~167 USD). The operator advertises introductory diving for ages 10 and above. PADI’s register lists the centre as a 5 Star IDC, the tier that also trains instructors, and counts 10 instructors on staff. Teaching languages on the PADI listing include English, French, German and Spanish, plus several others, so ask for your language when you book.

Certified nitrox divers get nitrox free, per PADI’s listing. A numerical group limit is not published; the operator advertises small groups.

Dive Trips and Sites

Silent Divers runs guided two-dive speedboat days from Samui. Sail Rock is the standard certified-diver trip, advertised on Tuesday, Wednesday, Friday and Sunday. Koh Tao and Chumphon Pinnacle run on Monday, Thursday and Saturday, so choose your day first and the site follows.

A Sail Rock day suits certified divers who want the pinnacle in the Gulf of Thailand. Koh Tao and Chumphon Pinnacle give certified divers other days to choose from. For the island-wide picture of the three routes and the seasons, see the Koh Samui diving guide.

Trips depend on offshore conditions and take a full day. The operator warns that November is difficult, so keep a spare day in your plan if you travel that month.

Prices

Silent Divers’ own site lists these headline prices in October 2026. Sail Rock and Discover Scuba Diving are “from” prices.

Booking takes a 20 percent deposit. Two sibling dive centres already on the site publish prices you can compare with these:

Discovery quotes before VAT, so the final bill there is higher than the headline.

Is Silent Divers Worth It?

Silent Divers is worth it if you want a PADI 5 Star IDC close to Chaweng and are happy to fit the weekday trip schedule. Its Sail Rock price sits between Discovery Divers and Easy Divers, and its Open Water price is the highest of the three in this table.

Skip it if you need a fixed daily Sail Rock departure, or if a smoke-free boat deck matters to you. A visitor who dived with the centre in February and March 2026 reported disappointing visibility on some dives and smoking allowed on the bow of the stationary boat. The same review, written in April 2026, describes 12 dives, hotel transfers, guides and free nitrox.

Getting There

The shop is at 39/8 Moo 3, Chaweng Beach Road, about 0.6 km from central Chaweng and about 2.9 km from Samui airport, both in a straight line. Boat days include hotel transfers according to the Open Water package and a visitor’s April 2026 review; confirm your pickup area when you book.

Shop hours are 11:00-19:00 daily on the operator’s own contact page. Boat departures are earlier, so visit the shop the day before a trip rather than on the morning.
