i got a brand new, never used, never wet oceanic fdx10 delta 4.
it retails at our favorite store for 540 bux, and with the 10% comes to about 490.
im letting this thing go for 450 or best offer.
it has never been used, never in a mouth, never wet.
i suggest that you test this in a controlled environment prior to using it (like all gear should be tested) if you would like me to, i will test it for you in my pool (not everyone has access to a pool) and i will go trough a full tank for you (only if you want me to after you buy it)
and yes, that is the same pic im using on ebay.
