I need to get a new pair of binocs. I would be using them primarily for turkey hunting so large objective lenses are not a top priority though I don't want a pair that are useless in low light. Lightweight is a priority. I would like to keep the weight at a pound or less. My wallet is not full right now so I don't want to spend $500 for a pair. Would the compact porro prisms be the ticket or what do you think?
