For those that say TSA doesn't care or read notes in checked inspected bags, I've had them write personalized messages on my notices (ike "Dive Safe" and "Thanks for the notice") or tape the TSA inspection pamphlet to my notice. I'm not saying they're all oblivious but sometimes they do care and read things.
I do try to carry-on my rebreather head or in some circumstances my entire rebreather on the flight. It's a 50/50 shot whether I get the full inspection or they completely ignore it. They're often more interested in my canister light.
Like others mentioned, sometimes saying the magic words "scuba equipment" gets them to lower their guard a bit.
I've traveled with 3L (23cu/ft) tanks probably a half dozen times. My procedure is to put clear tape over the tank neck and print out TSA's own procedures for empty cylinders on the bottom. I also clearly write on the notice. "This tank is empty."
The worst experience I ever had was trying to fly home from Mexico with my rebreather and 3L bottles from Cancun airport. The Mexican security agent was adamant that tanks and my scuba equipment were not allowed on the flight. He was furious and would not back down. He wouldn't even let me check them (I was carrying them on). I almost missed my flight and had to get a Delta supervisor involved after I exhausted my Spanish-speaking abilities. I had to go back down to check-in desk and have the agent come up to security with me. The Delta agent and Mexican security agent proceeded to argue about what was allowed on the flight. The Mexican security agent finally gave up in disgust and wrote down my passport information and what looked like the Delta supervisor's badge information. If I had not arrived at airport about 2 hours early I would have missed my flight. I no longer travel to Mexico with tanks. I did this 3 times (2 twice to Cozumel and 1 once to Cancun).
