Went on a cruise recently on Celebrity Summit out of Bayonne NJ. My scanner was impounded by shore security and labeled a "prohibited item". They turned it over to ship security since it was a repositioning cruise and the cruise ended in San Juan Puerto Rico. I was able to get the scanner back when I left the ship there. They didn't "find" the other scanner in my checked baggage so I still had one on the ship. The ship radio's are all DMR formatted so I could not hear a thing. I found it interesting that they are banning scanners but using DMR radio's, talk about overkill. The security officer on the ship also advised me that this policy will apply to all Celebrity and Norwegian Cruise line ships so I just wanted readers to be aware of that.
