When go to the beach or other similar activities, I just bring a semi-disposable rig that I won't fret over if it's lost or destroyed. A beat up K100 mech and an cheap tank (protank with rebuilt head) works great. I try to use something that is pretty well sealed to keep out dirt and keep an old carto condom on the tip when not in use. Shiny, high end devices are nice and all but sometimes a beater is indispensable.
