You may not be getting a range for a number of different reasons:
There are many reasons as to why you may not be able to the reach the maximum range on your rangefinder. The most common is type of target. The maximum distance is given using a reflective target. With non-reflective targets (animals) you will likely have to cut that range in half. The color and size of the target, stability, atmospheric conditions all play a factor as well. Ranging darker or black targets, smaller targets, through fog, over water, or into the sun will make it more difficult to get a reading back on your rangefinder.
