Camera is passed to and from the crew when entering the water. Never enter water from boat with camera.
Actually, after two crew failures at two different times (and both with amazing happy endings) I no longer allow the crew to do anything with my camera until I have schooled them. And if they will not listen to me then they get to put up with me climbing the ladder with my camera upon re-entry and I now ALWAYS jump in giant stride with my camera. I clip in on the boat to my coiled tether. I do not unclip until back on the boat or once the crew gains my trust I will unclip at the moment their hands take the camera and I am sure they have a good grip.
Over the years I have had my Nikonos dropped on the deck smashing the filter ring on the 28mm UW lens. I have had twos strobes damaged, one beyond repair by crew dropping them. I have had two lenses returned for dome replacement due to being thrown in the "rinse" tank after having specifically stated to the crew to hold my camera for me and then hand it to me or to place it lens up on my towel (when there is a camera table).
But, back to my current rig, let's see, the crew tossed me my camera after I entered the water at their insistence rather than handing it to me and and the wet lens (high dollars) spent a couple of nights on the bottom all alone. This was a drift in about 60 plus feet, I went after it but lost it. The camera bounced on the platform before bouncing into my reaching hands minus the lens. But, to the great credit of the shop and grateful owner of said lens, it was returned to me and all is well with it. Then, on yet another trip, the whole thing deep sixed in 60 feet of water but at least this time we were not on a drift and I was able to find it.
On the first day in Cayman, a few weeks ago, after me clearly asking the crew not to put my camera in the "rinse" tank as soon as she took my camera after I had just told her specifically not to, she went and put it in the rinse tank. This made me very upset, so, for the first day and part of the next couple of days I climbed the ladder with the camera much to their aggravation and would not let them touch it. At some point they decided hauling me up the ladder with camera was more difficult than following my not particularly challenging request to hold it for me and not put it in the rinse tank.
So, yeah, I have been jumping in with my cameras for years. And if need be I will come aboard with it also. And anyone not like it then they can be up for replacing it. I realize nothing is guaranteed, especially with the sea, but really now!
My tether screws into the camera tray with a 1/4X20 thread swivel and is secured both my torque and Loctite 271. The other end is a stainless clip that goes to my crotch strap ring (scooter ring). When entering the water I make a giant stride and with my camera held in front of me as it comes to water level I begin to raise the camera until I am fully submerged or nearly so and the camera gently follows.
My GoPro rig is simpler, it has a wrist lanyard with a captive bolt snap additionally. I can clip it to a D ring when I become bored with it. I also have the GoPro 3-way selfie stick also fitted with a lanyard and a captive bolt snap.
