Between two points in one plane is created a straight line, the fundamental principle of design for the SoltTrak pins. Without angling pins or using multiple rows of pins, the SoloTrak single row of overlapping snag-proof, rigid steel pins provides a perfectly straight row of aligned aim pins.

The famouse Metal Optic Pin has been re-engineered in a single row to achieve a zero pin gap for arrow speeds beyond 360 feet per second, with the additional size of the finer .010 pin diameter. This new SoloTrak configuration allows for multiple diameter pin sizes and the ability to add or remove any pin or chage fiver color with ease.

For example, at close range a .029 is the largest pin and easy to see, for long range a .010 can be added as a last pin to cover less of the target. SoloTrak pins are numbered 1 through 5 with the diameter embossed into the pin for easy identification.
