Was talking to a buddy of mine the other day - he's primarily a Sika deer hunter and mentioned how they are exceptionally quiet even by deer standards. I told him that as a relatively new bow hunter, but even with gun experience, my #1 most valuable piece of gear are the noise amplifying headphones I wear. I told him about it because Sika love swamp and I thought he'd make great use of a tool like this that would help him hear water sloshing way, way out. I can't tell you how many times I have heard deer well before i could see them, from long distances, with these things on; distances that are not possible with the human ear. I'd say that where I primarily hunt (hardwoods) I can consistently hear a deer slowly walking at 100-150 yards out, sometimes more. As a gun hunter is isn't as helpful because you can shoot at range and dont have to move much. However, as a bow hunter these extra seconds to get into position are invaluable. Right now I use an over the ear pair meant for shooting, but they help keep me warm in the cold months. I think next year I'll get an in-ear pair. Hopefully there's some out there that can blank out the sound of wind. Who else is with me?
