I would like to share my experience with the Pax Era and venue security.
I think that we all know that cannabis is legal in California.
Disney parks in the state are privately owned, and have a blanket "no-cannabis" policy. This even applies to edibles (must be difficult to enforce).
I have been bringing my Pax Era into Disney parks and other venues for some time. I have a leather tri-fold wallet, and I've been sticking the Era in the wallet and folding the leather flap over it. This hides the device reasonably well. I put my wallet in the dish with my phone and keys before walking through the metal detector. Recently I've been removing the pod and placing it in my pocket and just placing the battery in my wallet. It's a good thing that I started doing that.
On my last visit to the Disney parks the security guard working the metal detector removed my wallet from the dish and said it felt like there was a bulge in it. He asked me to open the wallet, which I did, revealing the Era battery. I told him it was a battery, and he asked me several times if I had the "top" to it. I said that I did not. He asked me if I had anything in my pockets, and asked to see the sweatshirt I was carrying as well. I denied having anything, and after several tense minutes he let me go with the device. It was clear to me that the guard had been trained to look for devices folded into wallets, and to question anything that looked like a vape device. If my Pax had been a Juul, and I produced a Juul pod, I'm sure he would have let me go.
This alarmed me enough that I decided to find a different way to bring the Era into Disney parks. I Googled "Pax Era metal detector" and found some Reddit posts claiming that people had gone through metal detectors multiple times with Era devices, and that the device was too small to trigger the detector.
Based on this I decided to do some trial runs without any pods on me. I put the Era battery in my front pocket, put everything else in the dish, and walked through without triggering the detector. I was relieved, but was not going to rest easy with only one test, so I exited and tried again. This time I went through a different lane, and this time the metal detector DID alarm. The security guard wanded me and detected the Era battery. I showed it to him, told him it was a battery, and he said "OK". Before letting me go he asked me to flip my belt buckle back so he could look behind it. I had nothing there and he let me go.
So the takeaway, for anyone who is curious, is that metal detectors CAN detect the Pax Era battery, depending on how they're calibrated. The metal detectors at the Disney parks must be configured to ignore belt buckles, because mine had a LOT more metal in it than my Era battery, and it has never triggered the metal detector. And security guards at Disney parks are trained to check behind belt buckles when someone triggers the metal detector in any way. Also my pod has never been detected.
I don't think I will change my technique for other venues like concerts or ball games, as they seem much less interested in vape devices, or what is crammed in my wallet. But security at Disney parks seemed to be trained to look for that kind of stuff.
