AN/PVS-7B Night Vision Goggles (NVGs)
AN/PVS-7D Night Vision Goggles (NVGs)
TM 11-5855-262-10-02 Operator’s Manual, NVG AN/PVS-7B, 15 Jul 1994
TM 09500A-10/1A, 30 Dec 1997
PVS-7 Night Vision Goggles allow the user to see at night using moonlight or starlight. PVS-7s can be hand held, head-mounted, or helmet-mounted. The goggles have an IR illuminator for illumination or signaling. An indicator lets the user know when the IR light is on. A separate indicator signals low battery. Automatic shutoff occurs on high light, when goggle is detached from the head mount, or flipped up on the helmet mount.
Weight: 18 oz
Focus Range: 20 cm to Infinity
Range: 150 m (Starlight), 300 m (Moonlight)
Battery: (2) AA or (1) BA-5567/U
Battery Life: 4-6 hours
Field of View: 40°
Interpupilary Adjustment: 55 to 71 mm
PVS-7s include a helmet mount and a head mount. The 7D include a compass. A 3X Magnifier attachment is available.
In complete darkness, such as inside buildings, PVS-7s are ineffective without IR illumination. The compass is 15° off. The IR illuminator illuminates only at a short range. The IR illuminator is visible to an enemy with NVGs. The helmet mount unbalances the helmet and causes neck fatigue. The 7B carrying case has a noisy velcro closure.
8. Usage Notes: The IR illuminator works well as a recognition signal during link-ups.

1. PVS-7 Night Vision Goggles allow the user to see at night using moonlight or starlight.
2. Major components and their purposes
PVS-7D have an (18)-item SL-3 Gear List. See Reference, pages B-4 through B-8.
Older PVS-7Bs were not issued with a Helmet Mount, Compass, Tether Cord, or IR Flood Lens. The helmet mount, NSN 5855-01-441-0401, is far easier to use and should be back-ordered for 7Bs.
A 3X Magnifier Lens is available as an optional accessory. See Reference, pages C-2 through C-3.
3. Battery Installation. Either (1) BA-5567/U or (2) AA alkaline.
4. Indicator Lights
LOW BATTERY - Red dot in right eyepiece.
IR beacon is ON - Red dot in left eyepiece.
OFF / RESET - turns goggles OFF. Resets Goggles after automatic shutoff.
ON - turns goggles ON.
IR - turns IR beacon ON. Pull and turn. New goggles have temporary ON.
6. Automatic Shutoff
Goggles shut off automatically in Excessive Light, when the goggles are removed from the Head Mount, or when the goggles are flipped up from the Helmet Mount. To turn goggles back on, turn switch to OFF / RESET, then back to ON position.
7. Goggle Adjustments. PVS-7s have four (4) adjustments:
Interpupilary Distance. The two eyepieces slide apart to adjust to the user’s interpupilary distance. Adjust the Interpupilary Distance so that each eye views each lens as a perfect circle.
Eye Relief. On the head mount and the helmet mount, the distance from the goggles to the user’s eyes needs to be adjusted as close to the eyes as is comfortable.
Objective Lens Focus. The main lens rotates to focus on objects closer or farther away.
Diopter focus. Each eyepiece adjusts independently to focus each eye on the image inside the goggles. Turn objective lens to focus on an object 20 feet away. Once focused, turn left diopter ring counterclockwise all the way. Close right eye. Turn left diopter ring clockwise until image first becomes clear. Do not turn past this point. Repeat this adjustment for right eyepiece, then re-adjust objective lens focus.
Clean lens with lens paper. Turn in for maintenance if goggles have shading, edge glow, flashing, flickering, or operate intermittently. Some blemishes or spots are not deadline issues. Goggle resolution can only be adjusted by higher echelon maintenance.
Always wear the PVS-7 on a mount. NVGs are not opera glasses to be worn around the neck and lifted to the eyes when needed. This requires one hand, making it impossible to shoot. The helmet mount is far superior to the head mount. On operations where helmets are not usually worn, such as boat raids, leaders may direct Marines to wear helmets solely as a platform for the PVS-7. Marines should be able to assemble all mount hardware in the dark.
Head Mount. Don Head Mount and adjust straps. Attach goggles to mount. Adjust Eye Relief by sliding mounting bracket toward or away from eyes.
Helmet Mount. Strap Helmet Mount onto helmet. Attach goggles to Mount. Adjust goggle height by loosening bracket knob and sliding goggles up and down. Adjust Eye Relief by sliding mounting bracket toward or away from eyes. Goggles can be flipped up when not in use.
10. Pre-Combat Checks
Remove Lens Cap. Attach Sacrificial Window OR Compass OR 3X Magnifier.
Attach IR Flood Lens.
Don and Adjust Head Mount OR Helmet Mount.
Make the four (4) goggle adjustments.
11. IR Beacon
The IR Beacon is for illuminating near objects in very dark conditions, or for signaling. The IR beacon CAN be detected by an enemy with NVGs. Newer goggles have a momentary ON feature. Turn Beacon ON by pulling switch out and forward. Red dot in left eye indicates IR is ON. Flood Lens attachment allows beacon to adjust from spot to flood.
How to Focus PVS-7
Install batteries in PVS-7. Don and adjust Head Mount or Helmet Mount. Attach PVS-7.
Stand behind 20-foot line.
Turn lights OFF. Turn PVS-7 ON. Turn IR illuminator ON.
2. Make the (4) PVS-7 goggle adjustments
Adjust Interpupilary Distance. Slide eyepieces closer or farther apart so that each eye views each lens as a perfect circle.
Adjust Eye Relief. On the head mount and the helmet mount, adjust PVS-7 as close to the eyes as is comfortable to acquire maximum field of view. Lens caps should cover eyes.
Adjust Objective Lens. Turn Objective Lens fully counterclockwise. Rotate Objective Lens clockwise until both vertical and horizontal charts are clearly in focus.
Adjust each Diopter Ring. Turn both Diopter Rings fully counterclockwise. Close right eye. Turn left Diopter Ring clockwise until image first becomes clear. Do not turn past this point. Repeat this for right eyepiece. Re-adjust Objective Lens.
3. Afterwards, when re-focusing for distance, adjust Objective Lens ONLY. Do NOT re-adjust Diopter Rings.

Procedure. Focus PVS-7 on target. Do NOT attempt to align head with sights. Acquire target using PVS-7. Align body so PVS-7 vision parallels weapon direction. Focus ‘over the sights.’ Pull trigger.
9. Read a map with PVS-7
Procedure. Lay the map on a flat, stationary surface. Holding head and goggles steady at a fixed distance, focus goggles on map. (20) centimeters is minimum focus range. Use a finger or pencil to maintain position on map when scanning remainder of map or looking at other objects.
Techniques. Tape all overlays to map to minimize moving parts. Fold map to minimize searching and folding in the dark. Use a second Marine to read notes or sketches, write notes, or talk on the radio.
10. Navigate with PVS-7
11. Estimate Range using PVS-7
Procedure. Acquire target with PVS-7. Estimate range to target.
12. Call for Mortars, Artillery, and NSFS using PVS-7 to observe
Procedure. Focus PVS-7 to infinity. Use the bracket technique to get rounds on target. Realize that it is difficult to estimate distance using the PVS-7 at night. HE rounds are clearly visible on PVS-7, sometimes the glowing shrapnel can be observed flying through the air.
13. Acquire CAS aircraft using PVS-7
Procedure. Focus PVS-7 to infinity. Divide up the sky. Using a map for terrain association and the aircraft’s final attack heading, sector off the airspace from which the aircraft will approach. Using all available eyes focused on this airspace, search for the ‘moving star’ with the aid of the PVS-7. Once the aircraft is acquired, padlock it. Do not look away.
Techniques. PVS-7 focused at infinity reduces the halo effect caused by the high luminance of the stars.
14. Call for Close Air Support using PVS-7. See Hand-held Laser Pointer TTP.
15. Execute surveillance with PVS-7 and 3X Magnifier.
Procedure. Attach 3X to PVS-7. Focus on target area. Scan continuously.
Techniques. 3X makes goggles heavy. For long periods of surveillance, rest goggles on a flat surface. Narrow field of view requires constant movement to cover sector of observation. Binoculars can augment surveillance even at night. Relieve observers frequently.
