That’s definitely not a bad deal for a good brand new spotter at $500 OP but I have seen some really nice used Razors or Kowa or Mavens for a similar price is all I’m saying. I bought (and sold) a used Kowa last year for a mule deer hunt in SD for under $700. It was really nice glass and I could definitely notice a difference over my diamondback spotter. I personally didn’t notice a difference between my diamondback and a friend’s vipers. I’m rarely using a spotter here in New England at all so I went back to the diamondbacks. Ultimately depends what you’re using it for, where you’ll be using it and how much you’re willing to spend.
