The GTP-RS in combination with the Javelin Lite bipod head and your trekking poles provides a sturdy base for rifle or crossbow shooting. The GTP-RS and attached head fit easily in your pocket. After attaching the trekking pole-legs it easily mates to your weapon using the Spartan magnetic attachment system. I use it with several different rifles ranging from calibers 243 to 30 and with a Tenpoint crossbow. The adjustable trekking pole legs make it easy to set up on uneven terrane, sitting or standing, and the Spartan head allows tracking targets, or locking in place. Using the leg attachments provided (carbide or rubber tips) with the GTP-RS it is a useful tool for sighting-in on a bench at the range. I very much value the high-quality machining and overall usability of the GTP-RS.
