Re: Long range spotting
What you are asking for is way out of a 'not to expensive' price range even if it is available to be had. For spotting you are going to want something that you will be able to make an educated correction based on the splash from the hit (if there is one). You do not need to see the exact hole 1/4 hole the bullet went through, you just need to have some one spot you a correct so that you can get on target.
Once you do and you're done shooting a group(s) go down range and assess the target yourself.
