the Pelican 1510 for Christmas so I have something for carry on. It's probably (okay definitely) overkill, but I figure it's worth it.
Yes, it is overkill.
Why would you want the extra weight and very limited internal storage capacity afforded by this superb product that is designed to withstand 100x worse than any cabin bag would be subjected to?
Pelican cases are designed to be checked-through or tossed madly into a truck. You should never open them in any sort of open boat environment. If you want to cradle it in your arms as you muddle through the airports, it's a waste of effort. Hermetically sealed boxes such as a Pelican are a major
red flag to TSA.
A nice bit of padding (with a t-shirt) and then inserting cameras into a comfy back pack- that's the way to utilize your "personal item" baggage allowance.
After hundreds of dive trips,
we carry prescription masks, computers and camera gear. If you're flying to the Bahamas or Mexico, I suppose you can elect to burden yourself with your entire dive rig and live to tell the tale.
Once you start traveling beyond the usual places in the Caribbean,
checking it through in a well tagged bag is the only way to survive the ordeal of 20 hours of plane flights and multiple stop overs.
Regulators are essentially bulletproof, using your wetsuit to pad the checked bag, and you're off. The incidence of theft of dive gear from baggage is an urban myth. No one will bother with bulky gear that has limited resale when the pickings are much better in the next bag.
Tag your bags with full routing info, hang three tags on each bag. Never fails.
Put THREE on every bag:
Laminate them at Kinkos, or just clear tape them onto scraps of bleach bottles. Use wax coated string.
