Howdy ! ...and Welcome to the Circus, er, um, I mean the Board.

You will love bowhunting...at least if you like the challange of getting close enough to you game to smell what they had for breakfast. What a rush it is to get right on top of them and know you won before you even take the shot.

Anyway, about your questions...

G-suit?
Not for me, at least not for bowhunting. For gun hunting at short or medium range, yes. After all, if they weren't one of the best all-time, all-terrain, camo systems, military snipers would probably be using something else, but not for bow.
Never tried one myself though, I just am afraid about it snagging the bowstring and getting in the way. Even with the "sneaky-leaf" system, I know a guy that swears he has had shots messed up by it. I think a g-suit would be worse.


Scent killer?
I've never invested in a scent-killing garment. When I started, I decided to try cheaper means first and see if they worked.
I hunt on the ground occassionally too, and I've had no problems with Robinson-Labs Scent-Shield line of of body soap, laundry soap, and scent eliminating sprays.

I've only been busted by scent when I've made the mistake of trying to set up my stand to quickly because I was late getting into the woods and got all sweated up. That'll get you every time. I just use the laundry soap on all my hunting clothes, shower with the body wash right before I leave the house, spray down my equipment with the eliminator and I'm fine.
I've had several deer walk right by downwind and never know a thing.


What else do I do?
Just buy a camo outer garment. layer other clothes beneath as it gets colder. and wash them all together adn only use for hunting.

Good luck!
