Patented in 1994 and still is the most accurate and technically advanced bowhunting sight made today.



     The Predator IV treestand sight pivots on a true ball bearing. Although it was chosen for accuracy the side benefit is, that it makes no noise. Because the inner race is held tightly by a screw and nut. Therefore, there is no side movement that would create noise. The stainless steel balls in the bearing are the only parts that are loose and they are packed with a lubricant. The pendulum cannot strike anything that would make noise either and that is why there is a short rubber tube behind the pendulum - to restrict movement. There is no treestand sight made that is as quiet as Predator IV - that's guaranteed!



      you, the customer, requested a fiber optic pin for better daylight visibility. A green, 40 thousandths diameter fiber optic filament was chosen for best visibility. Now with ten inches of fiber optic affixed in such a manor that will give superior visibility in low light to a point where if it were any darker you would not be able to see the deer.

     Most other sights use .029 because archers who shoot competition want a very small pin tip because they are aiming at an inch and half #12 ring on 3-D targets out to 60 yards.  But for hunting conditions - that’s not the case.  You want a pin that has the highest visibility in those densely shaded areas you hunt.  You want a pin tip you can see and aim accurately in the lowest light conditions.


   This system was especially designed for low-light superior accuracy. The semicircular Glow Guard is used as part of the aiming system and is accented with a luminous coating for glow-in-the-dark visibility. When viewed through a peep sight, the guard is to be centered in the peripheral view, (match a circle within a circle). Without the guard being visible at extremely low light, you cannot see when their sighting system is accurately lined up.



     As described above, the Predator IV system can be purchased with or without the auxiliary light (LED). It is mounted on the pendulum itself so after you have adjusted the narrow beam LED for maximum reflection, it will never pivot out of the light beam. This is a major flaw with other pendulum systems. If a non-lighted system is purchased first, a conversion kit can be purchased as an upgrade feature at a later date. Since it does not cast light onto the deer it is legal in almost all states. Now it is obsolete due to the new "STARLITE PIN".



     For the first time, the guard is being used as part of the aiming process. Not just for protection of the pendulum. The concept is to match a circle within a circle. The Glow Guard being within the circle of the peep hole with minimum air gap between them, then place the pin on the target. This action becomes instinctive and provides quick to accomplish consistent aiming. Unless one is stacking arrow upon arrow, everyone will experience a decrease in arrow grouping diameter and a lot fewer stray shots that one just never counts as a good shot. One will also find that he can shoot quicker because he would not have to concentrate as much to maintain the pin in the middle of a floating hole. (the view through the peep)



     Most people think that only one eye can be used when using a peep sight. This is because most everyone that has tried, incorrectly chose the wrong of the two images of the pin. The remedy is to briefly close the non-sighting eye, establish the guard inside the peep as previously described, put the pin on target and open the non sighting eye. What will occur for 90% of hunters is the pin will stay on target because we have introduced a larger third item into the picture - the guard through the peep. The sighting eye will maintain the proper alignment of the peep, the Glow Guard, the pin and the target. The non-sighting eye will pick up the light image of the target and binocular vision is being used. And that is very important to us humans at low light. Although the system was designed to be used with a peep sight, the pendulum will work almost as precisely without one. Almost, because you would lose the low light advantage and must truly rely on the highly polished shooting finesse of aiming which takes countless hours of practice.



     Most hunters are using portable tree stands that will vary in elevation from time to time. This is not a problem. It is recommended to sight in at 15 feet if actually hunting from 15 to 30 feet. No variation in accuracy has been found with the Predator IV even with an additional downward sloping hillside. The downward limit has not been found yet. For ground shooting, it has been found that with the Predator IV system that all bows regardless of arrow speed are accurate around 30 yards. All bows will be high at 20 yards. Bows with arrow speed around 200 fps will be higher at 20 yards than bows with arrow speeds 280 fps. You would need to do some ground shooting to know what to expect and make adjustments to their aim point depending on the distance.



     In the design phase of making this sight, several materials were selected to provide as little friction at the pivot point as possible. All failed! Only a true ball bearing passed the test for providing a jerk free action of the pendulum while adjusting for range. The stainless bearing used is also injected with a synthetic lubricant - not to make it more friction free but to dampen the swing created by drawing the bowstring. When the hunter is ready to shoot the pendulum will be steady and ready. The lubricant used is designed for aircraft landing gear - it will not freeze.
