Many years ago I did a bit of diving and loved taking pictures with my D300. My gear has had about 20 dives on it but it has not been maintained so I don't know if things like o-rings and batteries are up to snuff.
I am not offering the camera or lens at this point but the gear I have is as follows:
Ikelite Housing for Nikon D300 digital camera - paid $1,424.95
For Tokina 10-17mm lens:
Ikelite 8" Dome port w/shade - paid $ 379.95
Ikelite Super Wide Body Extension Ring -paid $ 117.95
For 60mm lens
Ikelite SLR Flat Port, 4.125" paid $141.95
Strobe & arm:
Ikelite Substrobe DS-125 Strobe with Diffuser paid $759.95
Ikelite DS-125 Battery paid $125.00
Ikelite Substrobe Smart Charger 1.5hr for DS-125 & DS-200 -paid $94.95
Ultralight Base Adaptor for NEW Ikelite SLR Release Hndl. -paid $23.95

3 Ultralight Fisheye Clamps (15 degrees side movement) -paid $89.95

I also have a great backpack that holds everything which is in perfect shape. No idea what I paid for it but it wasn't cheap and was intended to keep my precious gear safe.
I want to find someone local who can just swing on buy lower westchester and pick it all up for $500 or best offer. Time to clean house.
Who knows, maybe I'll throw some split fins in too.
