I try to make sure everyone in the group has an FRS radio. While some may consider it unethical to use radios to assist experienced or trophy hunters in finding or stalking game, I think I even read it violates B&C rules, radios are certainly helpful in calling for assistance dragging one out, coordinating meeting back at the truck for lunch or for emergencies.
I do have a chrono but it doesn't come on hunting trips.
