Observations
A VARIANT OF THE B SERIES WITHOUT A LASER POINTER, distinct from the already-covered B21LS in this comparison, which has one ('LS' for laser). Same sensor, same NETD, same recalculated IFOV of 3.41 mrad: the only documented difference between the two models comes down to this single accessory — one more example of range segmentation via an isolated feature rather than a technical upgrade, in line with what was already observed with the B20 and B20S.
Neither image fusion nor a visible camera are mentioned, unlike the B21LS, which has one according to its own already-consulted datasheet.
