The Sentinel EPS is not a universal accessory and that's exactly the point. Designed and manufactured specifically for the Tevin Sentinel S2, the EPS Eyepiece delivers a level of precision fit, optical alignment, and system integration that off-the-shelf solutions simply cannot match.

Every dimension, every tolerance, and every interface point on the Sentinel EPS was purpose-built around the Sentinel S2 ensuring a connection that is rock solid, perfectly aligned, and ready to perform from the moment it mounts. No adapters. No compromises. No compatibility guesswork.

Not every situation calls for a helmet mount. The Sentinel EPS doubles as a handheld eyepiece bringing the Sentinel S2 closer to your eye for a more natural, comfortable viewing experience than holding the unit at arm's length. Whether you're glassing an area from a static position, conducting a quick scan, or simply prefer handheld operation, the EPS gives you that flexibility without carrying additional gear.

Pair the Sentinel EPS with the Sentinel REACH Arm and you have a complete, battle-ready helmet-mounted system or pick up the Sentinel ACES Kit and get everything in one box.

If you run the Tevin Sentinel S2, this is your eyepiece. The only one built for it.

Purpose built. Perfectly matched. Sentinel engineered.
