The Onyx Platform

ONYX - from the Ancient Greek ὄνυξ, meaning "claw" 

The Onyx is a saddle platform that simply has it all. It is a fusion of our EDP, Mission, and Wingman platforms, and results in perfect size and function. The Onyx contains an Angled Perimeter -  angles on each side of the platform, with built-in non-slip ridges, containing the ideal contact points for foot placement and comfort when leaning, rolling to stand, or turning to shoot your weak side. The Platform also was built with the newClaw Design - a singlecast post, standoff, and stomp pad built and integrated together.

The Onyx is the end of the platform debate, everything you could ever want from a saddle platform.

Little more weight but well worth it for size on longer hunts

After many uses this stand is exactly what I been looking for. Have used smaller and larger in the past, and this is exactly what I have wanted. The taper accommodates well for long or short hunts. The onyx ability to grab steadfast into all sorts of trees is a game changer. Thanks for such a well built platform.

I recently picked up the Onyx on a whim. I already had a platform I liked but wanted another one. I didn't think any real difference could come from the angled edges and stomp pad claw though. I couldn't have been more wrong. It's hard to explain but once you've used the Onyx you'll know without a doubt that this is the BEST platform available. Another outstanding piece of gear from the guys at Trophyline.

Perfect in every way…not to big, not to small, and definitely not edges that hurt your feet!!

Top Notch Platform

Extremely well built platform. Trophyline has really out done themselves with this one. It bites into the tree really well, and it nice and quiet. 10/10
I have total confidence in this platform
