Should I pack my own BCD and regulator?

Only if you're a very experienced diver or going somewhere remote. Most tropical destinations have quality rental gear that's regularly serviced. Shipping or checking these heavy items risks damage and costs extra.

What wetsuit thickness for tropical diving?

3mm wetsuit for most tropical destinations. Some divers prefer 1mm or rashguard in very warm water (80°F+). Always bring something - even warm water feels cold after 45 minutes underwater.

Can I pack dive weights in luggage?

No. Weights aren't allowed in carry-on or checked luggage on most airlines. Rent weights at your destination - every dive shop has them and they're usually included in dive packages.

How do I pack wet gear for the flight home?

Rinse everything in fresh water and let it dry as much as possible. Pack in your mesh bag inside a plastic garbage bag. Put this at the bottom of your suitcase away from clothes. Some smell is inevitable.

How to Pack Diving Gear for Tropical Destinations

Pack your mask, fins, wetsuit, and dive computer in carry-on luggage to avoid losing essential gear. Ship or rent heavy equipment like BCDs and regulators at your destination. Use a mesh bag for wet gear and pack reef-safe sunscreen.

Pack essentials in carry-on. Put mask, fins, snorkel, dive computer, and certification cards in your carry-on bag. Airlines lose luggage, but you can't dive without these basics. Wrap your mask in a towel to prevent scratching.
Decide: ship, rent, or pack heavy gear. For BCDs, regulators, and tanks, choose one: ship gear ahead to your hotel (costs $50-100 but arrives safely), rent at the dive shop ($30-50 per day), or pack in checked luggage (risk of loss/damage). Most tropical destinations have quality rental gear.
Use a mesh dive bag. Pack a large mesh bag for wet gear after dives. It drains water and lets equipment dry. Fold it flat in your luggage - it takes up almost no space when empty.
Pack reef-safe sunscreen. Bring mineral sunscreen without oxybenzone or octinoxate. Many tropical destinations ban chemical sunscreens. Pack enough for your entire trip - reef-safe options are expensive or unavailable in remote areas.
Bring backup basics. Pack an extra mask strap, fin strap, and dive log book. These small items prevent trip-ruining equipment failures. Tuck them into corners of your luggage.
Organize certification documents. Bring physical certification cards plus photos on your phone. Some dive shops accept digital copies, others require physical cards. Keep cards in a waterproof case.
