RE: Rangefinder
I have a Bushnell YARDAGE PRO for my Golf, $150.00 at cabellas. It's not water proof, It is compact enough to carry in my cargo pocket, I've used it practicing at the range. It is good out to 200 yds on soft targets (I carry it when walking my dogs and range off them when I get the chance) and 400+ on reflective. I'm happy with it.
My hunting buddy spent considerable more on the SCOUT series, It is waterproof has a zip mode and is slightly smaller than the YP. He is happy with it.
