Benefits of an Engineered Airfoil

• Superior flight characteristics - Designed by archers
• Installs in seconds - No glues, fletching tools, cleaning or scraping
• Instantaneous rotational torque - Simple broadhead tuning
• Consistent flight every time - Injection molded, highest quality
  materials and tools
• utmost arrow penetration, stability and retained energy (speed)
• Faster the flight the better they fly
• 70% less cross wind drift
• No flight deformation - Reduced tail walk, wobble and chatter
• Outlasts vanes 10 to 1 - Field replaceable rugged, durable
  and reusable
• Saves money - Buy bare shafts (use nocks supplied with arrows)
• Legal for hunting in all states, countries and NFAA, FITA and
  *IBO events
• You must use a fall away rest with FOBs.

I'll be honest - I didn't want to like these.  I thought that they looked goofy and, quite frankly, I've been told of a million products that are supposed to improve your arrow flight.  Well, after much prodding from John Smith (monofletch), I decided to try to prove to him that these were just another gimmick.

I was wrong.  I am now a FOB believer.  At 20 yards, you may notice a difference with field points, but the real deal comes at 30 yards and beyond.  Below are pictures of my test results.  I shot a Pearson TX-4 with Gold Tip Pro Hunter arrows and pink (yeah, pink) FOBs.  These test results made me a believer.

I don't know if you can see it or not, but there are 4 arrows here.  One shot through the FOB of another and its FOB popped off.  This is a group at 40 yards.

The picture above is of the same 40 yard group, but shows how closely the arrows are stacked.
