I have a Bushnell 1000y model.
It works well and seems rugged. It uses 9v batts, and is simple to use.
At every range I've used it, the 100y line lases at 100 give or take a single yard, and I don't lase from the yellow line. I really don't know how else to test it, and would like to know how he determined they are not accurate.
Leica is supposed to be excellent, and their 1200y has my eye, but mine works and I suspect the local guy had what he was pushing and didn't have Bushnell in stock.
