As is known to most users here, a proper bipod is an extremely valuable tool for the LR hunter. There's several really good bipods available and in my opinion the final choice can be left to personal choice. There are no "do all" bipods, there is a compromise somewhere in all of them. It could be weight, size, adjustments or similar.
In this film I shoot a deer through a keyhole over very marginal support made solid by a bipod. Just no way this shot would have happened without a proper bipod with proper feet.
