Vortex blade slope - Vortex 6x Blade Slope Golf Laser Rangefinder

Took a while to get the settings correct and how to get the pin to lock in(you have to double click) but compared to my bushnell the distance is pretty accurate. Slope not so much. I was getting slope reading not anywhere close to what they should be. I am on a flat course and most of my holes are 0 slope, I was getting 1,2,3% grades on the slope adding way to many yards. I bought this because I use Vortex Scope and Binoculars and I love those products. This is not to the level of the Bushnell products at this stage.
