Arbor GPS vs K2 Instrument

How they compare

Both boards are designed for all mountain and freeride and powder riding. They share a directional shape — different nose and tail; built to ride forward with better float in powder and drive on groomers. The Arbor GPS has a camber profile (arc underfoot for strong edge hold, pop, and stability on hardpack—lively and precise), while the K2 Instrument uses hybrid (rocker/camber) (mix of camber and rocker zones for all-mountain versatility—grip, float, and play in one profile). Both are rated 7/10 flex (stiff). The Arbor GPS targets expert riders while the K2 Instrument is aimed at advanced riders.
