Seeing your video reminded me, not sure why, I havent managed to use any of the beacons much. Only built two and carry them around but not set them up yet. I am still in the early stages I suppose but really need to start using them to mark places.Personally I just reload the last save if my Seamoth gets destroyed LOL.
My first encounter with a reaper https://www.youtube.com/watch?v=7blK0TTY5nU - seems they mostly just make one pass then go away for a bit before trying again so not too big a threat aslong as you keep an eye on where they are coming from.
