I use the inexpensive Bushnell Sport. I doesn't hit ya to bad in the wallet and works just fine for all intents and purposes in the bowhunting woods. I also use it when hunting with my muzzleloader and have no problems getting it to pick up on a deer and give me a accurate reading out to around 200 yds. which is all the farther I would expect to shoot muzzleloading. I would however recommend a more expensive model if you were planning on using one for rifle hunting and ranging extremely long distances.
