LocLine Arms

[mdmbike to scuba]

Some foam will compress at depth and lose most of it's buoyancy. I think the most popular ways people have been adding buoyancy are closed cell foams and enclosed PVC pipes. I believe the swim noodles that Steve recommended are closed cell, so they should work well if you can cut them into a shape that works with your system.

Ron what size pvc tube should I use if I go with the closed cell foams? Any thoughts I have TL50 lights.

I am following this question also. My rig is VERY heavy with the DS51. I tried to attach a threaded pvc pipe with caps on both ends, hung off the bottom of the camera... Didn't work worth a hoot...

LineLoc did not work for me. The SL50 lights are just to heavy. Although maybe if they were wrapped in shrink tubing they may work, but I doubt it.

Here is my solution to both the arms and to add additional buoyancy. And BTW, I love the lights!

Dave,what size tube did you use? What did you put inside it? Thanks Mark

I have Nocturnal SL50 lights with loc-line arms and wrapped the arms with 3mm neoprene and tie wraps (diver's duct tape). This added buoyancy and stopped the arms from bending under the weight of the lights. I also wrapped the lights with 3mm topped with a cold water glove minus the fingers. The velcro strap on the gloves snugs things up nicely.

Andrew, Do you have a pic of what you did? Also where did you get the 3mm neoprene? This what I thought of doing but didnt know where to get it. Mark

I just finished working on them, so do not have any pics yet, but will be posting some in the next week or so. I tried several things to add buoyancy and this worked the best for me. I got the neoprene from a friend. The gloves were my old ones. You can buy neoprene on the www. I found a few links on this board, but didn't want to pay the shipping to Canada. Also try asking your LDS. They usually have some kicking around. I've heard of some people using an old 3mm wetsuit. I might try using an inner tube over the neoprene instead of the tie wraps.

Thanks Andrew for your help. I leave next week so any ideas will help out alot. I wont get to test anything until my trip so I'm trying to come up with back up plans. Mark

Seems like everyone has their own method for adding buoyancy. I tend to go for what's cheap, easy and light weight.

I've used "last-a-foam" closed cell foam, which worked very well. It was cheap, light weight, but a little bit of a pain because you need to coat it with a resin. If I were to do it all over again, I'd experiment with empty water bottles or those swim noodles 1st.

I did prefer to put the buoyancy on top. Putting it on the bottom made my system turn upside down.

Ronscuba, What size tube do you think would work? Now I already bought two tubes they both are 1-1/2 and 8in long. I also bought four caps for them. Help me here, If I get this right, I would put as much of the noodle in side both tubes and glue the caps in place. Boy the airport people are going to love me!!!! Mark
