Yea I mean, they all use the same tubes. An ANVIS tube is just an MX-10160, same as a PVS-15, PVS-31, Sentinel, MOD-3, etc.
Between the two, the differences are quite subtle, but I'll outline the stuff I found below. Any cons are really just me being nit picky.
Sentinel Pros:
- Rugged as fuck.
- IP Adjustment is really solid. Tube housings have zero wobble.
- Different mounting options for aux power solutions.
- Left hand device manipulation.
This was a big deal for me. Most if not all PVS devices have the controls set up for left hand, as do the mounts. In short, it's more intuitive to manipulate everything with your left hand.
- Comes in FDE.
- Extremely lightweight.
- Built in illuminator has two modes, one is god's flashlight.
Sentinel Cons:
- Slightly more expensive.
- No modular capability.
- Depending on helmet & mount, while using the L4G24 some users may find they would like to get the eyepieces closer to their eyes.
MOD-3 Pros:
- Rugged as fuck.
- Cheaper compared to the Sentinels and other binocular housings.
- Modular, can pass off a monocular to a friend.. but, you didn't spend all that money on binoculars just to hook up your scrub friend! :P
- While not as lightweight as the sentinels, still lighter than most binocular setups.
- Due to the dovetail placement, I can put the MOD-3's through my eyeballs with an L4G24 if not careful.
MOD-3 Cons:
- Tubes housings wobble.
Not a deal breaker, but kinda wish it didn't do that.
- IP Adjustment can be kinda janky on its clicks compared to the sentinel, not as precise... probably contributed by the wobble on these systems.
- Power Knob is on the right hand side, and is reversed instead of where it should be... you find yourself hitting your Illuminator whilst trying to power the device off.
- Illuminator leaves little to be desired.. it's pretty weak.
- Poor placement of the battery compartment, it can be difficult to access with the tubes in the way.
