Hello, sorry for my bad english but i would like to make a suggestion what our loved primitive mod developers must append into game. As you all know that we dont have a scuba gears in primitive mod. Thats good and i like that, but bad point of that we are in primitive position to tame, explore the under water world. Our community thought that would be good and best solution for that to have a old school Diving Bells. Take a look the next description page of the diving bell http://adventure.howstuffworks.com/outdoor-activities/water-sports/diving-bell2.htm. So what do you think about a idea? It would be nice if air pipes could be linked with rafts ..and y can install some air fabricators on the raft etc.
