For the price, the Bushnell 1600 Fusion were VERY hard to beat...and the MILE are now proving to be that much better.
The actual range is pretty much the same. I've pegged reflective targets out to around 1900 yds, but the unit itself is just a step up from the original model.
My main unit is a Vectronix PLRF10 and my back up is a Leica CRF 1600. If I had some spare funds I would also have a Terripin.
This decision is directly related to the distance you need a unit to be precise and return good data.
I have owned and field tested almost all units from $700 to $4000 and the three I list are the only 3 that will fulfill my needs with accurate results in any situation.
Ljcamp what distances have you used the RX TBR1000 and how accurate does it seem to be? A buddy of mine wants to order one and asked me for my input, but I have not seen reviews and have not used one. He is probably going to buy it regardless because we get a GOV discount on Leupold optics and he only plans on shooting out to 600 yards.
I have a Leupold RX-IV TBR and have ranged reliably out to 885 on reflective targets and animals out to the high 600's. Not the best there is but hard to beat for the money.
I have a Leica 1600. It's very handy to stow it in a shirt pocket for a quick access and range from bow range to LR . I've ranged beyond 2K yards. Last season, I range a herd of elk at 1830 and harvested a young bull at 931.
