I use to hunt Colorado a lot. I read just about everything I could get my hands on. I have a large stack of Colorado Outdoor magazines that are free for the taking if anyone wants them. They range from late 1980's to the early 2000's.
Get what you think they can handle. The more they shoot, the better they will get. With a BB, pellet, or .22, they can shoot 100 rounds a day, not so much with a centerfire. At least I couldn't afford to pay that bill.
A friend has one that we use. He first had the short range system and it did good to go 400 yards. He traded it in for the long range system. We have used it to 600 yds. with no problems. It works best with a laptop or note pad over a cell phone.
Set it up at your target and get the signal on...
I use to take my wife hunting with me all the time, we didn't get much hunting in though. She has killed her share of deer and caught a boat load of fish. She gets mad now when I go and don't take her.
