We bought 2 for our Jeeps. Very easy to install and very easy to use. We went with the bundle for the extras and 3db gain antenna. We will keep our hand helds to loan out on the trail and when camping. Lots of online information out there, too.
Perfect for our trail rides in the Wrangler. We mounted the main unit under the passenger seat, ran the antenna out the back, added a microphone extension up the 'B' column to hang our mike from our overhead molle panels—
Great base unit for my rock crawler, compact when space within arms reach are at a premium. Thinking about getting a second unit for my towing rig during cross country trips for faster and more reliable comms between vehicles.
