Safety & Course Standards — Beginner-Friendly Summary

We translate complex agency rules into plain language so divers know what to expect before booking. These baselines come from globally recognized training agencies and widespread instructor consensus.

Thailand Dive Map does not create standards. We spotlight useful transparency signals and encourage shops to share them publicly.

Agencies referenced: PADI / SSI / NAUI / RAID / CMAS
Focus: Transparency & beginner clarity
Audience: New divers & curious travelers
Scope: Course baselines, not safety scores

Section 1

Instructor Qualifications (Baseline Expectations)

Most agencies require instructors to keep active teaching status, professional insurance (where needed), and current membership with their training body.

PADI Open Water Scuba Instructor (OWSI) or higher
SSI Open Water Instructor or higher
RAID / NAUI / CMAS instructor equivalents
Active membership with their agency

Section 2

Equipment & Maintenance (General Expectations)

Divers expect well maintained rental gear. Agencies encourage regular inspection, documented servicing, and basic transparency about equipment age and care.

Regulators serviced per manufacturer guidelines
BCD inflators and valves functioning properly
Tanks visually inspected / hydro tested per local law
Masks, fins, wetsuits kept in usable condition

Requirements vary by country. Thailand Dive Map never judges the quality of equipment; we only show if shops disclose maintenance habits.

Section 3

Typical Course Components (Open Water Example)

Beginner programs generally follow a similar structure regardless of agency. Details change slightly, but the journey is recognizable worldwide.

Theory segment (e-learning or classroom)
Confined water training in a pool or pool-like setting
Open water dives — commonly 4 dives minimum
Basic rescue skills: mask clearing, regulator recovery, buoyancy
Final knowledge review or assessment

Each agency sets its own standards, but the above gives new divers an easy frame of reference.

Section 4

Student-to-Instructor Ratios

Exact limits differ by training agency and dive conditions, but the guidelines below are widely referenced.

Confined water

1 : 8

Instructor to student (assistants can increase this)

Open water

1 : 4

Typical recommendation for normal conditions

Assistants

+2–4

Certified assistants allow higher ratios per agency rules

Dive shops often choose lower ratios for quality or safety reasons. Assistants (Divemasters) let instructors supervise more students while staying within agency rules.

Section 5

What Thailand Dive Map Does (and Does Not Do)

Our mission is to promote transparency, not to certify or grade operators.

Summarize global standards so beginners know what to expect.
Check whether shops disclose safety, course, and ratio info (transparency).
Do NOT score or certify safety — we are a data index, not an auditor.
Encourage shops to share updates if information changes.

Important

Safety Reminder

Use this guide as a conversation starter with instructors and shops.

Thailand Dive Map does not certify, audit, or grade dive shops.
We consolidate public, commonly accepted safety baselines so travelers can ask better questions.
Safety is a shared responsibility of agencies, instructors, operators, and divers themselves.
