First of all,seperate NV from thermal. They are two completely different things. They work differently,they are used differently,you even hunt with them differently.
Read up on them all you want. Reading and learning is a good thing. Then ....... like college,pick one(something)and stick with it.
Finally .... once you know the basics,there is absolutely no better way to learn than talking to someone that is not a bullshitter with an aganda. Find one and pick their brain. Let them teach you from their expierances. Same for getting into reloading ammo.--- pruhdlr
