PVS-14 installation tips on Panobridge:
- We recommend using a U.S. quarter as a tool to tighten the slotted screw, as a quarter perfectly fits inside the slot.
- It is important to use sufficient torque in order to ensure the PVS-14 is firmly mounted and will not move out of alignment.
Tether point attachment tips:
- We recommend using 550 cord / paracord and / or a dedicated night vision goggle lanyard to connect to the rear of the Panobridge's central portion, which has a tether point attachment built in.
- Do not tether directly to either PVS-14, as this will pull the monocular rearward, out of alignment. Always connect to the Panobridge's tether attachment point on the rear.
Adjusting joint tension:
- The vertical and AFOV (panning) joint mechanism tension may be adjusted by tightening or loosening screws with the appropriate hex keys.
- The ideal tension allows the user to easily move the joint while also ensuring the monoculars do not come out of the desired position during rough activities.
- As delivered, the maximum recommend adjustment for additional tension in the vertical joint mechanism is 1/4 to 1 full turn clockwise. Damage should not result if additional tension is added, but the joint will eventually bind.
- As delivered, the maximum recommend adjustment for additional tension in the AFOV joint mechanism is 1/4 to 1 full turn clockwise. Damage should not result if additional tension is added, but the joint may bind.
- The most important tip is to ensure the ocular (eyepiece) lenses are not too close to the eyes during fitting and use, as this creates a "toilet paper tube" or "scope shadow" effect where defined black circles around the outer edge are both visible and distracting. Put on a pair of safety glasses before donning your goggle to make sure the offset is sufficient. In use, you should see one wide, panoramic image with only faint, fuzzy, and thin circular lines separating the split images.
- Because the height of the monoculars will change when switching from tubes-forward (traditional 40 degree FOV) to tubes-rotated (wider FOV), it is recommended to adjust your night vision helmet mount to a position between the best one for tubes-forward and tubes-rotated so that, if a quick change between FOV is necessary, you will not have to adjust the night vision helmet mount in the field.
- In order to eliminate eye strain, it is best to collimate both PVS-14s after they are installed on Panobridge. A technician can easily complete this task in a few minutes by using a special machine. However, it is possible to perform collimation without a machine on a DIY basis, though not necessarily to the same level of perfection. Do not attempt a DIY collimation if the goggle is to be used in a professional capacity.
