I bought my Nikon Pro 440 last summer to improve on my yardage estimation for 3D. I also took it hunting with me this year as well. It is dead on accurate to distances measured out to 200 yards, and seems to be accurate well beyond that (don't have any premeasured distances past 200). I have also dropped it out of a tree stand 3x this season, including one nearly 30 foot drop, and I also dropped it into 6" of standing water by accident (oops
) and it still works perfect with no fogging inside, or broken parts. I love this little rangefinder, and would highly recommend it to anyone out there looking for one at a good price. I also bought off ebay for around $160 or so.
