Iv been using thermal for the past 3 year my spotter the pulsar hd38s is getting a bit long in the tooth now but still works fine I was using it with digital nv add on until I bought a pulsar trial xq50 scope so I'm a bit spoilt at the minute I would just go for the pulsar Helion xq38f spotter and stick to shooting with nv for a while but I must say thermal is very impressive once you have shot with a thermal scope don't think you will go back to nv
