FOBS instead of fletchings?

KoolKat45 · Oct 15, 2007

Anyone heard of these or better yet used them? Pretty impressive if they work like they claim..

Interesting concept. I'd like to see how well they work.

lollygagger · Oct 16, 2007

hmmmmm i'd probably stick with 2"-4" vanes

lobsterman · Oct 16, 2007

stick with plastic fletchings 3"

im assuming you cant use a whisker biscuit with those?

I base my shot on the exit wound, and I feel it makes not only a more humane kill but a better blood trail to pass through. I don't see that passing through. I almost always shoot down on a deer, and I need the pass through to get a great blood trail, if the arrow doesn't exit on the lower side of the vitals, your blood trail will only come from the entrance wound which is on the upper body and the blood will come from below the upper wound and be very light compaired to a complete pass through.

Good luck, with that though.

Garbo I agree with your pass through comments but this "fob" thing actually detaches on impact, makking pass through better. I'm intrigued.

Very interesting. But, I watched the demo videos and had some questions. He claims that the air moving into the circle moves slower than that on the outside producing lift. I'm no expert, but I do make my living flying, and that statement that he made doesn't exactly go along with the laws of physics. Heavier air on the inside produces lift normally. It could reduce drag. Besides, if the air flow is equal all the way around, how does it lift anything. Stabilize maybe, but lift, I don't know??? Interesting concept though. I'd like to see it in action.

Meanwhile, I'm sticking to the blazer 2 inchers!!! If it ain't broke, don't fix it!

I USE THEM AND LIVE IN FORT WALTON IF ANYONE WANTS TO SEE THEM FLY. WHISKER BISCUITS ARE A NO GO BUT PAUL AT STARRFLIGHT POINTED ME TO A LIMBDRIVER REST AND I SHOT MY BLAZERS WITH IT BEFORE MY FOBS CAME IN AND IT WAS MUCH BETTER THAN BISCUIT FOR GROUPS AND NOISE. WITH BLAZERS AND BISCUIT I COULDNT GET MY FIELD POINTS AND BROADHEADS TO HIT ANY CLOSER THAN SIX INCHES OF EACH OTHER LEFT AND RIGHT UP AND DOWN I DID OK. WITH FOBS AND LIMBDRIVER REST THEY HIT THE SAME PLACE. I HAD TO MAKE A LINE ONE FOOT LONG ONE INCH WIDE TO SHOT AT FOR TUNING AS THEY GROUP SO TIGHT THAT EVEN WITH MY REST OUT OF TUNE BROADHEADS AND FIELD POINTS STARTED TO HIT EACHOTHER. AFTER THEY ARE ON THE ARROW YOU CAN TURN THEMTO LINE THEM UP WITH BROADHEADS AND IT DOES HELP GROUPS. I AM NEW TO ARCHERY ANDALL SUMMER SHOT FOUR INCH VANES AND BLAZERS THOUGH WISKER BISCUIT. THAT WAS ALOT OF FUN BUT WITHOUT FOBS AND LIMBDRIVER REST IWOULD OF PASSED ON HUNTING AS MYBOW DIDNT WANT TO TUNE AND GROUPS NEVER GOT VERY GOOD.I GOOGLE SURCHED THE FOB AND ONLY FOUND ONE PERSON THAT COULD NOT SHOOT THEM AS HIS FACE WAS TO FAT AND HIS CHIN GOT IN THE WAY OF THE FOB. AS FOR ME IT WORKS IN PLACE OF MY KISSER BUTTON. I ALSO CAN USE ONLY ONE SIGHT PIN OUT TO 20 YARDS 30 YARD PIN IS AT OLD 20 YARD PIN. I HUNTED ALL WEEKEND OUT OF A STAND AND ARROW NEVER CAME OFF OF HOLDER THAT CAME WITH REST. MY SON IS GETTING THIS SAME STUFF FOR CHRISTMAS FOR HIS BOW.

very cool.... it's true... shoot what works for you... the limbdriver is a nice rest as well

>My background is Mechanical Engineering. I had spent the better part of 12 years working at a rocket ranch (Hughes Missile Systems). I am also lucky enough to say I have not missed an archery Elk hunt in 25 years. I am even luckier to say it has been with the same group of friends. My thoughts regarding bodies in motion come from crunching the numbers. My thoughts regarding arrow flight comes from hunting and the frustration of getting a broadhead to fly. <o

>The drag the FOB produces (about the same as a 3 inch fletch)is funneled through the ring wing and is turned into lift (360 degree lift) the ring wing acts like an airplane wing but in 360 degrees. So in effect, the FOB is trying to pull itself apart. It is basically an air gyro. It does not lift the back of the arrow; it provides as much lift up as it does down and side to side. All we have done is taken the drag component and used it for good. A fletch provides drag but that is it. After that it is thrown away (wasted energy). Not to get to technical, but the air that enters the FOB is captured by the ring wing and is compressed by the fins which causes the air to become more dense (heavier) and more efficient. At the last 3/4 of the FOB the air is decompressed which creates extra spin. It is the pressure differential of the air inside vs. outside the ring wing that creates circumferential lift. <o

Paul do Fobs work as well as they claim?

Well, I guess "they" would be me and a bunch of happy customers.

They really do work as advertised. You do need a drop rest that is set up correctly.

The engineering is very straight forward. A ridged airfoil vs. 20,000 year old technology. As bow speeds have increased, the trusty vane has reached its limits. I shoot a large fixed blade Zwickey. As soon as I hit 220 fps a few years back, vanes no longer could do the job. That is why there are so many smaller lightweight (an expensive)heads these days. Its not the speed that is the problem, it is the stabilizer.

Do you use a drop rest?

KoolKat45 · Dec 10, 2007

Not using a drop rest now but super interested in Fobs so a drop rest ison the have to have list. What drop rest's do you recommend for Fobs? Thank you for your time and help Paul

soalsrfr · Dec 10, 2007

I picked up a Trophy Taker Shaky Hunter when i was looking at them but haven't outfitted my bow for the FOB'syet.

What rest are you using now? Are you looking at a full containment rest like the Ripcord or a conventional rest like the Drop Zone or Trophy Taker? Do you use a string loop? What arrows do you have?

The TT rest should work great if set up per manufactures instructions. If you use a peel and stick arrow guide, it may need to be trimmed down for clearance. Do you use a string loop? Arrows?

I would suggest making a clearance tester. Just take a heavy stock paper or card and cut a 1 inch diameter circle. Then punch a whole in the center. Nock up your arrow and hold the rest in the up position. Then slide the paper disk up and down the arrow. When you get to your rest, hold the arrow in the up position, and let the rest fall. Slide the paper tester over the rest and check for clearance at the arrow guide. I would like you to have about 3/16 clearance.
