What do you use to adjust the buoyancy of a 3/4" Locline arms?
I saw in a recent Blueworld episode that they were using something that looks like a StiX Jumbo float, but I couldn't find one that were made for the locline (Or do the one for ULCS arms just fit on a locline arm?). I have also seen float from BTS, but not sure how they would work as some version has rubber band around the foam, while the version sold for the locline doesn't (seem like they would be prone to falling off when you jump off the boat).
I have used these which can be purchased in different sizes to use whatever combination you need to dial in your rig buoyancy. Just drill out the center to slide onto your Locline arm diameter. I have done that on my ULC style arms but I see no reason it would not work on Locline arms. You probably would want to stick with some wider diameters if you need more flotation rather than wider thickness so you do not limit the arms range of motion. I have not found these to compress at all down to 75 feet. They are cheap to boot so you can get many sizes to see what works best.
