Spend a little time on the Fedex International quick rate site...
Even though price is not an obstacle, it looks like you could buy a new set of gear for the cost of shipping yours a couple of times.
I travel with a 45lb. checked bag full of dive gear/clothes. So I used that for some quick quotes. For all of these, I used June 3rd as a starting date.
Unlike airfares Fedex doesn't get cheaper months in advance.
Started with the offshore banking capital of the Caribbean - Grand Cayman.
Overnight (4-June arrival) is $462.
Next delivery is 4/8 for $403.
how about Panama? Possible business/diving location right?
FedEx International
Economy would arrive on the 9th. For $912.13.
Now let's say you're lucky enough to have a client in Tahiti.
Same June 3rd ship date - June 9th arrival - $1060
June 12th arrival $850.
And I didn't price the return cost to NYC.
My suggestion would be go real minimalist. Buy/break down a BP/W into it's component pieces and carry it on. Some are probably more suited to that than others. Mask,
Aeris Accel travel fins in a backpack as your "personal item".
Or something like a
Zeagle Covert - a minimalist version of a Ranger. It rolls up like a fat newspaper. Aqualung Zuma's fold pretty small also. Assuming you're not traveling to cold locations, get a lycra skin/1mil suit and if you need more rent on-site a wetsuit to put over it on-site. Several other mfr's make a soft-plate BP/W style also, Zeagle's Express Tech, Hollis Ride, Dive-Rite TravelPac - there's others.
I have a TravelPro roller that has room for 2 thin business suits in the cover pocket - it's a tri-fold so they stay pretty nice. Leaves the entire bottom for dive gear (regs/computer/mask) change of casual clothes etc. I also carry a
full-sized video housing in that case. Laptop fits in a pocket on the outside. If I am forced to gate check it - has happened twice - I slid the laptop out, grab my documents from the top pocket and let it go. I also unbox/uncase just about everything and wrap it in clothes. My issue is my fins are XL so I wind up checking a bag anyway.
