My first thermal was the Krypton. Thought I might be having POI issues, so I sent it back to Pulsar. They sent back a Thermion XP50 Pro, with the laser rangefinder built in, no questions asked, worth $1000 more than the Krypton . I thought this was extremely generous of them and wanted to pass on a public thank you. (Now I just need to figure out how to set it up and use it!)
