I have a home built near eye unit and a Photon XT. I would say that they are comparable to each other as far as image and range with the right illuminator. The home built will run 12+ hours on 2 18650 Panasonic batteries. The Photon will run about 2-3 hours on 2 AA batteries. The home built can be used on any scope without rezeroing. The Photon is a dedicated NV scope for 1 gun, unless you can write down or remember the X & Y settings for the different guns. I can record with both but need a DVR to do so. To be honest, I use the home built more than I use the Photon due to its interchangability and battery life. You can view the results from the home built on talonairgunforum in the hunting section. Look for Barn Rats 2018. Keep in mind the actual image is way better than the recorded version.
