We just returned from a week in Bonaire. In the past, I have always carried my regs/computers and camera with strobe in my carryon roller bag. After checking bags and proceeding to security, I was informed by TSA agent that I could no longer carry strobe in cabin and it had to be checked. It was too late to recall checked luggage and I was able to check my carryon after removing the regs/computers. We tore apart a travel pillow and wrapped strobe in it and a sweatshirt. It arrived safely. However, I wanted to warn others who may not be so lucky.
