The Grub Guard is one of Gary Yamamoto's best kept secrets. It makes the Swim Senko (or other Yamamoto baits) almost completely weedless. The Grub Guard will bounce off of weeds, even that nasty slimy stuff. It will bounce off most of the time, not bog down in it.
I also use these grub guards on spinner baits to prevent knot sliding up the wire
Really does witk!
I was bottom bouncing a cut tail worm in 40 degree water and I had no luck. I headed a Grub guard to give the worm a "head", what a difference! Not only does it work for what it's supposed to do, it helps change the presentation!
PERFECT FOR SWIM BAITS
I've used a product that is similar to Yamamoto Grub Guards, but they only came in one color. I was able to get 4 difference colors to match different soft plastics. These work great in helping baits come through grass and cover.
