My SO bought one to use at work for around $80.00. I’ll ask him what kind it is and get back to you. I can call him from home on it, and it’s 7 miles away.
In film/TV production, I’ve used Motorola. The sort used in production are about $400 a pair. But their consumer model is the Talkabout, with a range of 18 miles. They’re about $80 a pair. I’m sure something like that would be fine.
