RE: Do you think Scent Lok is a must?
I don't even think you need it, let alone it being a "must have". It may help some but there is no way it eliminates your scent.
People used to kill deer without camo, let alone scent loc clothing.
The first deer I killed it was 75 degrees outside and I was wearing black jeans, a camo T shirt and a baseball cap. And I was only 13 feet in the air in this skinny little tree. The deer had absolutely no clue I was there until I shot one of them. I don't believe scent is your biggest enemy, I think its movement and noise.
