I run flushers but I think sometimes we get way to technical. Imagine this an e collar device hanging around your neck. One whistle hanging around your neck. A go-pro attached to your hat. A GPS locator hanging around your neck. A vest full of 25 shot shells. Two or three birds in your vest. A shotgun weighing 6-10 pounds. A hoodie because it is windy and cold. Gloves. Chaps strapped to your belt. Water bottles on a fanny pack. A simple dog first aid kit. License, truck keys, cell phone, shooting glasses, ear plugs... How much stuff can a guy carry, keep track of and let alone use! I guess I have been hunting too long and have seen too many gadgets "I gotta have."
