Have you read the Sig warranty on their LRF's? I ask because I have read more than a few people posting at LRH and other similar WS that Sigs LRF warranty is quite poor. I have no first hand experience with Sig's optics CS and I'm in no way bashing Sig and yes I own a Sig 2200 and it has worked superbly for me, (as well as my cheap *** friends who keep barrowing it for every out west hunt) but thankfully I to date haven't needed any CS from Sig's optical division.Been using a SIG Kilo 2400, I don't think you can beat it, never used one as good as this. Can range deer out to 1200 that I know, I've been told that it will range soft light absorbing targets to 1500 and reflective to 2500- 2600. Happy shooting.
