Rocksolid guarantee

Shop with confidence. If it’s not working out, you can return it (consumables, electronics, undergarments and swimwear excluded).
Really. If it's not up to snuff after you use it (a couple times) you can still bring it back. It lasts longer than 30 days, but not forever. We'll be fair about it.


Head out to repeat a favourite hike or grab your HALO rig for a training jump. This watch will keep you in the know. Blacked out design, rugged nylon strap and night-vison-friendly backlight suit the Core Alpha Stealth to a particular user. Sunrise/sunset times for 400 locations around the world. The altimeter tracks your ascent and descent rates, and logs them for review. Once you’re at rest, the barometer mode automatically kicks in, so the Storm Alarm can warn you of sudden, severe pressure drops. Need to navigate a retreat? Use the compass mode to sight, lock a bearing, and go.
