3-16 is good. The thicker it is the more durable and stiffer it will be. The thinner it is the less space it takes up. Depends on your prey and how long you make it.
Just wondering does the line never get caught on fins, when I dive I go around 30 feet deep and have a 40 feet line. But when I go into shallower water(10 feet for example) the line gets somewhat loose and messes around with my feet. I was wondering if there is anithing I can do to fix it or if this is normal wirh any buoy line
Some lines tend to be a bit stiffer and won't wrap around you as easily. You could check out the reef rope. That's usually a good inexpensive option. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1JJIlAx4434.html
That's an excellent suggestion Alejandro. The brummel splice adds more complexity and this solution works just fine while also being simple and sufficient.
