I travel on airplanes several times a year and have just given up trying to go through the xray. i just make sure I can get myself unsnaped from the pump quickly and tell them I need to be patted down. The information I received was sketchy, first they say..yes you can go through security, then they say no you can't go through with the pump WHAAAA!!! I give up. Also the remote definately cannot be xrayed so if that has to be checked for "bomb residue" then may as well just get the pat down. Go early, I am old so it gives everyone something to look at...Hey Look they are patting down another old lady LOL.
