hi wantonmien
i just saw this post so want to share my experience
i am a recreational diver, a so-called UW photographer too and dive mostly warm waters. i am not a TUSA seller!
i am using TUSA Voyager. not a perfect BCD but the price is very reasonable for a light (comparable to many BP/W), very durable BCD.
materials are combination of 800/400 denier nylon. thick/thin at the right places. nicely padded for your comfort.
ample pockets to keep your stuffs, and many D-rings too. you can tug your SPG into a special pocket which is a cool feature.
i put my sausage, snorkel, writing slate, macro lens, gloves, everything inside those pockets!!! no need to turn myself into a christmas tree. it comes with a set of simple integrated weight pouch.
doesnt have a velcro cummerbund and with the self adjustable waist buckle, you will feel less squeeze unlike "normal" BCD.
it has 2 tank bands so your tank wont wobble. one of the best tank bands I have ever used.
it is a hybrid BCD, you get the best of both worlds.
the downside of this BCD is zippers, d-rings are made of plastics to reduce weight.
well, with the price I pay for this BCD, I am a happy man.
make sure you get the correct size! and try to google ScubaLab/ScubaDiving review for this BCD.
