Opti-Logic's Micro II rangefinder is a great little product. It is extremely small and fits in the palm of my hand and will fit in any pocket and will never get in the way. The Micro II has a range out to 800yrds and is very easy to use. It has a bright red LED display making it excellent to use in low light conditions which is typically when I use my rangefinder. The Micro II also has the vertical angle compensation technology which is great for bow hunters or anyone shooting at any angle. Being waterproof, you don't have to worry about hiding it in your coat during a rain storm. This is a great product and I can't wait to use it more and test it out in the field.
