The other growing trend that Impulses followed were the addition of stylish milling patterns and designs, suited for different retailers and sponsored teams. This has become a popular trend for the more expensive markers of today. There were over 30 customized body styles and parts available known as "Private Labels" before the marker was discontinued. Contingent to this was the growing number of parts and accessories available for the Impulse line as well, from various manufacturers and developers, which allowed nearly every part of the marker to be swapped for an "aftermarket" version. The serial number of the marker is located on the right-hand side towards the back.
