How FOBs Work
The FOB is a single part that replaces any type of three or four fletch application, either vanes or feathers that are normally applied to arrow shafts.
The fixed FOBs, as covered on this web site, are designed to be used with fall away rests only!
Standard FOBs are designed for all standard Internal Component System carbon shafts (ICS) using a standard 1/4' nock as produced by Gold Tip, Game Tracker, Beman, PSE, Redhead, Cabela's, Carbon Express etc. and Easton Super Swage aluminums (Cobalt). See arrow chart on order page for list of specific arrows.
Axis FOBs are designed for use with ALL Easton Axis, Full Metal Jacket, A-C Super Slim, Beman HIT Blackmax and MAX-4. The Axis FOB is also for use with ALL Carbon Express Edge and Edge Hunters. See arrow chart on order page for list of specific arrows.
Micro FOBs are designed for use with ALL Harvest Time Archery HT-1's and ALL Victory VAP. The Micro FOB are for use with f/g nock arrows (NO-unibushings). See arrow order page.
We have not tooled up to facilitate standard aluminum shafts using uni-bushings, ACC's and G-nocks. Some of our field testers have already made nock adapters to use the FOB on their aluminum uni-bushing shafts with great results. E-mail us if you are interested in making a nock adaptor for uni-bushings.
At first glance, the FOB appears to be a no-brainer piece of plastic that you would find in a kid's meal at a burger joint. Well, nothing could be further from the truth. Starting with the age old principal of Keep It Simple Stupid (KISS) our engineering team went to work and kept the KISS principal foremost in their thoughts. If man has learned one thing from history it's that simplicity of design will always outlast and outperform complexity in a hostile field environment - hunting for example.
The function of the FOB is therefore very simple indeed. One has only to slide a FOB onto the back of an arrow shaft and insert the press in nock of his or her choice and the arrow is done. Due to the superior design and stringent quality control of the FOB, each and every arrow will be the same - perfect every time!
There are a number inherent issues with vanes or feathers starting with the time consuming and tedious process of either replacing them when damaged or applying them on new shafts. I'll bet that most of you folks out there have a bunch of damaged arrows sitting in the corner waiting to be refletched - I know that we used to. Finally, the issue of high-speed stability, especially with broadheads, rears its ugly head. Our wind tunnel/strobe light testing of vanes and feathers reveals significant instability at moderate to high speed due to the fletching folding up and chattering or vibrating. You simply have to see this phenomenon to fully appreciate just how poorly a fletch performs under these conditions. Now throw in a crosswind and they really struggle to perform adequately. It's not the vanes or feathers fault, they are doing what they were designed to do and they have done it remarkably well over the centuries.
The issue is that mankind has pushed the technology envelope so far that the old fashion fletching has exceeded it's design capability - There is simply no margin left for these old trustworthy friends to use.
The Nitty Gritty
I know all this sounds good, but let's take a look at just how the FOB accomplishes all these great things:
In flight is where the FOB's aerospace design really demonstrates its superior capabilities. As soon as the arrow leaves the string, the powerful steering forces of the FOB's ring wing instantly stabilizes the shaft flex paradox that all arrows are subject to when shot. At the same time, the three FOB struts impart an quick and consistant spin on the arrow, which normalizes any inherent shaft straightness run out (usually .002" - .006"). Because the FOB is lighter than three 4" vanes and glue, its initial arrow velocity is higher than that of a fletched arrow. Since the FOB arrow stabilizes more rapid than the fletched arrow, less speed robbing air friction is spent in the first few yards of flight enhancing the FOB arrow velocity delta over the fletched arrow. The stability that the FOB imparts on the arrow makes broadhead tuning simple and the arrows fly true regardless of arrow speed or cross wind forces. Big broadheads at high velocity under complete control - WOW!*
See Broadheads and Tuning.
To summarize all that technical stuff, the FOB arrow starts out faster, stabilizes quicker, shoots flatter and hits harder. Simple huh? Couple the technical advantages with the ease and simplicity of use and you have a product that will improve your shooting, save you time and lower your frustration level significantly.
*Compared with 3" and 4" plastic vanes.
OK, Admit it... You all have a bunch of arrows that need work.
Give FOBs a try... You won't be disappointed!
