You were both invited by your clients? unusual. However, You are providing a service, not a club.For you to do that service well, I would think you would need to be nearby, and alert for the benefit of the client. So if you have a shot, the client would have the same shot at the same target. Thus robbing the paying customer.
By all means correct me if I am wrong, but I think the guide should guide. The only weapon the guide should carry should be a back up in case of malfunction, or danger (bear, cat...ect)
The only real difference between a good tracker and a bad tracker is observation. All the same data is present for both. The rest is understanding what you are seeing.
