  • Improved safety
  • Tool-free string replacement
  • 330 fps maximum arrow velocity
  • Up to 100 foot-pounds of energy

Steambow’s patented technology uses the field-proven compressed air or CO2 canisters that are commonly used in airguns and paintball guns to make quick work of cocking, loading and decocking the Steambow. All it takes is the push of a button to load and cock the Steambow. Decocking the Steambow is just as fast and just as safe.

More highlights of Steambow’s pneumatic crossbows include:

  • Nearly silent cocking and decocking with a push of a button - OPC
  • Collapsible configuration for ease of transport
  • Can be safely stored loaded 
  • Longer life than conventional crossbows

Incorporating an all-black, tactical theme and sending arrows downrange at up to 330 fps with a formidable maximum 100 foot-pounds of energy, the Sen-X Onyx is capable of taking down a variety of wild game. It also makes for a fun target-practice tool and affords people with physical limitations who are unable to operate a conventional crossbow an opportunity to participate in the highly rewarding shooting sport.

Whether you've been thinking about getting into archery or are already a seasoned practitioner, the Sen-X Onyx Tactical Crossbow by Steambow is definitely worth a look. Order yours today at!

Things I liked: Easy to use for handicapped people. Unique principle to cock the crossbow. It takes no effort for the shooter.

Things I would have changed: Concentrate on using compressed air instead of expensive CO2 cartridges.

What others should know: I saw this product on a YOUTUBE video, in Germany. The inventor and retailer for Europe is an American expat who lives in Austria, and went on a German show, to demonstrate this product. I really admired the capabilities of this crossbow. And now it's being either imitated or actually being imported for USA sales. I would dearly love to own one of these crossbows, however, the price point is way beyond my means. Being a senior citizen, this product would reduce the wear and tear on the (my) efforts it takes to cock a regular crossbow. And to change a broken string, this makes is very easy. For you with deep pockets. knock yourselves out! Get one. Maybe someday the prices will come down to a point that many people can afford to buy one.

  • Luke from USA asked:

    What hunting arrows r compatible?

    • Mark from USA:

      The Steambow bolts are specific to the Sen-X.

  • Keith from USA asked:

    Where is it made?

  • John from USA asked:

    Do you also sell the Steambow power reduction fitting which reduces the power and air usage by 1/2 ?

    • John from USA:

      I primarily shoot my crossbows for shorter range target where the standard power would be unnecessarily loud and use up the tanks faster. I can only think of 2 other common crossbow models which offer user adjustable power levels and think that it is a major selling point compared to other crossbow models.

    • Tyler from USA:

      Looking at the power reduction blue kit, they should be available down the road. Just curious, why are you interested in it?
