What to Buy and Bring for a Diving Course

A diving course needs more than masks, wetsuits, and tanks. Prepare one complete equipment setup per diver, plus spare and safety items for the group, registration, refreshments, and changing areas. Confirm rental quantities early, because suits, regulators, cylinders, and dive computers may not be available at short notice. Check every participant’s size and certification requirements before ordering, and arrange filled cylinders close enough to the course date that pressure and transport are manageable.

Tips

Count one mask, snorkel, pair of fins, wetsuit, flotation vest, regulator, and dive computer per participant, then add at least one spare of each size-critical item for the group.
Arrange one diving cylinder per diver for each planned in-water session, plus a few spare cylinders if the schedule allows repeated dives or delays. Confirm filling and transport at least 48 hours beforehand.
Pack safety equipment separately so it can be reached immediately: first aid and oxygen kits, life rings, emergency blankets, emergency lights, surface marker buoys, and diving lines should not be buried under personal gear.
Prepare registration supplies for the reception table, including participant records, emergency contacts, medical certificates, dietary information, walkie-talkies, and a megaphone. Keep storage bins or clothes racks available for separating dry clothing from wet equipment.
Plan refreshments by headcount: allow 2–3 drinks per person for the first hour, then about 1 drink per person per hour. Buy plates and reusable glasses for the full group, and set out coffee and tea before registration begins.

Frequently asked questions

How many diving masks and wetsuits do I need for a diving course?: Plan one mask and one wetsuit per participant, matched to each person’s size. Add at least one spare mask and a small range of spare wetsuit sizes if you are supplying equipment for a group.
How many scuba tanks are needed for a diving course?: For one in-water session, prepare one filled cylinder per diver. For two sessions, plan two per diver, then add spare cylinders if the schedule includes equipment changes, delays, or repeat dives.
When should I reserve diving gear for a course?: Reserve rental gear at least 1–2 weeks before the course, especially wetsuits, regulators, dive computers, and cylinders. Confirm sizes and the final participant count no later than 48 hours before the first session.
What safety equipment should I bring to a diving course?: Bring a first aid kit, oxygen kit, life rings, emergency blankets, emergency lights, surface marker buoys, diving lines, and water temperature meters. Keep these items accessible throughout the course rather than stored with general equipment.
