Why GMRS Over CB for Off-Road Communication

Customer Reviews
I've used portable radios which is limited to wattage which limits your range. This radio has unbelievable range and even works great in the city with all the obstructions. Very simple to use and installation was a breeze. Totally worth it and im glad with my purchase. I would 100% recommend this product as you will not be disappointed.
Thank you John! Safe travels!
I've try other radios and Rugged by far is better, the range it has is unbelievable, and is user friendly, well recommended.
This radio is the most convenient and reliable radio you can get if you’re doing tons of trips a year, those hand held’s are nice but if forget to charge them or even forget them at home cuz it’s happened, having this radio is the best ready to go accessory you can have!
