We have an Oregon Scientific and it is portable as the main unit looks like a walkie-talkie and it fits into a small base. It has SAME technology and we set it up wherever we are (by county). We look on the map to be familiar with an area if an alert sounds. To us, it is an essential piece of RV equipment. I also have multiple phone apps like Weather Bug. However poor cell service means no weather alert if you are only using an app.
