The Hangtime Hook: This is a neat little gadget for watching a movie when you are lying back in the wilderness somewhere in your hammock. I can’t say I am so addicted to TV that I do this often, but I have done so a couple of times. It requires a ridgeline, which is a good idea anyway if you want your hammock to hang a little ‘flatter’. I also makes for a handy place to hang various bits and pieces.: https://ridgelinemediasystems.com/ I suspect it will soon be available from Tassie hammock manufacturer Tier Gear.
Now available A$28.50 https://www.tiergear.com.au/shop/shelter-systems/guylines-ridgelines-and-hardware/hangtime-hook
