Bought 3 Phantoms for family after seriously considering getting shot tracking systems. I chose this because while I can use the phone app with the Phantom, I can get all the important data I need on a large screen that's designed for use in bright sunlight, including shooting distance, at one great price without having to mess around with my phone. not intended for use in bright sunlight. All three of us used Phantoms without opening the phone app. It just wasn't necessary for our purposes. It's nice to know it's meant to be played on an unfamiliar field. The Phantom is fast and accurate. Being able to get the last shot distance when I want is a very useful feature. The automatic hole feed worked perfectly. I had some questions and called support twice. Both times we spoke to friendly, knowledgeable US support reps. Outstanding support experience. All three like the Phantom. Highly recommended.
