I bought one for my father 2 years ago because his neck bothers him while walking and carrying a shotgun.
BEST $20 I HAVE EVER SPENT!!!!!
Not only did it allow my dad to hunt longer and in more comfort............it goes right on my gun when dad heads back to Florida
It is absolutely a must for walking days. You don't even realize you are carrying a gun. I can walk all day and not get tired.
As for being able to get into shooting position quickly?? I was walking with my safari sling and my hands in my pockets when a buck got up in a field and tried to trot into the sunset...........took about 2 seconds for me to get that gun up, pop the safety and put a slug behind his shoulder. With that gun hanging on my shoulder I don't get that buck.
Great product.
