     I saw my first SIGHTRON II riflescope yesterday and I it looked a lot like a a leupold. It was pretty clear and I liked it. It had good eye relief and I believe it was constant. I read on their website about their patented adjustment system they call EXACT TRAC.   If it is patented then why is it exactly the same adjustment system that is in the Weaver Grand Slam scope called MICRO-TRAC. How can they be using the same design? Oh well, does anyone out there own a SIGHTRON II and if so how does it stack up against some of these better known scopes?

I own a couple of Sightrons, including a SII 3-9x42 Mil-Dot and I am very happy with them.  Optically SII is equal to Leupold VXIII for less money.  I've been told that Sightron makes glass for Leupold which would explain it.

 

ExacTrack is not exactly like Weaver's MicroTrack.  I do not have time to search for their patents, but I think one has integral erector tube ring and another is not and weaver has 4-point contact while Sightron has 3-point contact.

Ditto on Koshkin's post. I have a Sightron SII 3X9X42 and also a Leupold Vari XIII 3.5X10X40 and I would be hard pressed to say where I think the Leupold is better. I spent less than $190 for the Sightron, and as you can guess, considerably more for the Leupold.

Micro-Trac ® 4 Point System
 





What is the Micro-Trac 4 Point System?

All riflescopes have an erector tube. These tubes are equipped with a means to adjust one end. This causes the point toward which the scope is looking (along with the crosshairs) to change. The Micro-Trac 4 Point System is similar to an automobile's dual independent suspension. Any adjustment made to the tube for windage is independent of any elevation changes. Therefore, when you change windage, elevation is unaffected and vice versa.

Why the Micro-Trac System is superior?

Most conventional conversion systems use 2 screws and 1 spring to adjust their erector tubes. Eventually, adjusting one screw "too much" will cause the spring to inadvertently affect the adjustment of the other variable. These other systems do not operate independently from one another like the Micro-Trac.

Most systems also have the screws baring directly down on the cylinder, whereas the Micro-Trac system bears down on a specific point of contact. Just like a ball joint in a car, this gives you better precision. The Micro-Trac erector tube is always being directed from the same point; angular motion is consistent.

Why does everyone need the Micro-Trac System?

The Micro-Trac 4 point System provides far better control of crosshair adjustments making it much easier to sight-in a rifle. Click adjustments are always consistant to a minute of angle.

The Result: Only the Weaver Grand Slam and Weaver T-Series offer such precision adjustment in a zoom scope.

 

 

Sightron's Exact Trac

 

 

They use a ring to achieve the constant contact point but as far as I know they do not use the four point contact system.  I think Weaver has their system copyrighted and patented.

 

The Micro-Trac 4 Point System is similar to an automobile's dual independent suspension. Any adjustment made to the tube for windage is independent of any elevation changes.
