VIVI Voyager 8310 8×30 HD Compact Rangefinder Binoculars
VIVI Voyager 8310 8x30 HD binoculars are the lightest model in the Voyager family, built for professionals who move far and fast. At just 570g, they disappear into a patrol vest or survey pack, yet they carry a genuine working toolkit: an 8x magnification with a wide 8° field of view (120m at 1000m), a mil-based rangefinder reticle for estimating distances and target size, and focus-free optics that are sharp the instant they reach your eyes.
Product Description
The VIVI Voyager 8310 8×30 HD binoculars are the lightest model in the Voyager family, built for professionals who move far and fast. At just 570g, they disappear into a patrol vest or survey pack, yet they carry a genuine working toolkit: an 8x magnification with a wide 8° field of view (120m at 1000m), a mil-based rangefinder reticle for estimating distances and target size, and focus-free optics that are sharp the instant they reach your eyes.
The BAK-4 Porro prism system with FMC multi-layer coating produces a vivid, high-contrast image with accurate color and stable depth. Because there is no focus wheel, security officers, surveyors and field inspectors can raise the binoculars and read the scene immediately — an 18mm eye relief keeps the view comfortable for glasses wearers through long shifts.
Sealed dustproof, waterproof and fogproof, the VIVI Voyager 8310 shrugs off rain, dust and humid mornings on foot patrols, forest transects and rail-side route walks. For a compact, wide-field observation tool with reticle capability, it is the carry-anywhere choice of the line.
Featherweight Field Design
At 570g — the lightest in the Voyager series — the 8310 supports all-day carry on patrol, survey and hiking routes without neck or pack strain.
Wide 8° Field with Rangefinder Reticle
The 120m@1000m field makes it easy to acquire moving targets, while the built-in mil-scale reticle supports estimating distances and sizes from any position.
Focus-Free Instant Readiness
With no manual focusing system to adjust, the image is always observation-ready, letting you react to what happens rather than to your equipment.
Why Choose the VIVI Voyager 8310?
The VIVI Voyager 8310 is the streamlined, no-compromise-carry option in the 8×30 Voyager pair. It packs the family’s core working features — a rangefinder reticle, focus-free optics, BAK-4 Porro prisms and a sealed housing — into the lightest chassis of the series at 570g. If your work is measured in kilometers walked, grams carried is a spec that matters.
Its sibling, the VIVI Voyager 8310C 8×30 HD Compass Binoculars, adds a fluorescent mechanical compass and optional tripod support for only 5g more (575g total). Choose the 8310 when your priority is the purest lightweight observation package with reticle ranging; choose the 8310C when directional reference and tripod mounting for fixed observation posts are part of your workflow.
With a wide 8° field, the 8310 excels at scanning: sweep a treeline, fence line or crowd without re-aiming, then use the mil-scale reticle to log distances and sizes — all without touching a focus wheel.
Product Features
- 8×30 Optical Configuration: 8x magnification with 30mm objectives balances reach, brightness and an exceptionally light body for mobile observation.
- Ultra-Light 570g Chassis: As the lightest Voyager model, the 570g weight supports hour after hour of carry on patrol, survey and hiking routes.

Application Areas
Security and Police Patrol
At 570g, the 8310 rides comfortably through a full foot-patrol shift, and the focus-free 8×30 optics come up sharp instantly when a situation demands immediate observation.
Land and Resources Surveys
The mil-scale rangefinder reticle supports estimating distances to boundary markers and features, keeping field survey records quantifiable from any vantage point.
Forestry Surveys
The wide 8° field lets rangers scan whole treelines quickly, while the sealed housing handles dew, rain and dust on forest transects.
Power Safety Inspections
8x magnification brings insulators, conductors and hardware into clear view from safe distances along transmission corridors.
Wildlife Observation
The light 570g body and wide field make the 8310 easy to keep at hand on long walks, ready for quick looks at birds and animals along the trail.
Hiking and Travel
Compact dimensions of 165 x 75 x 115mm slip easily into a pack, so quality optics are always available on trails and sightseeing stops.
Sports Events
The 120m@1000m field keeps fast play in frame from the stands, with vivid FMC multi-layer coated optics rendering colors faithfully.
Archaeological and Site Research
The rangefinder reticle supports estimating distances to features across a dig site, aiding documentation without approaching sensitive areas.
Railway Route Assessment
Field teams can observe distant terrain, structures and crossings along proposed alignments, with the reticle helping gauge relative distances.

FAQ
Are VIVI Voyager 8310 binoculars waterproof?
Yes. The 8310 features waterproof, fogproof and dustproof construction, keeping the optics clear through rain, dust and humid field conditions.
What is the field of view of the VIVI Voyager 8310?
The VIVI Voyager 8310 offers a wide 8° field angle, equal to 120m at 1000m — one of the widest views in the Voyager family, ideal for scanning and tracking.
Can the VIVI Voyager 8310 be mounted on a tripod?
No. The supplied specifications for the 8310 do not include tripod support. The binoculars are designed as a handheld, focus-free field tool; if you need tripod mounting in this size class, the VIVI Voyager 8310C lists optional tripod support.
How much do VIVI Voyager 8310 binoculars weigh?
They weigh just 570g — the lightest model in the Voyager series — making them comfortable for all-day carry on patrol, survey and hiking routes.
What is the difference between the VIVI Voyager 8310 and the VIVI Voyager 8310C?
Both share the same 8×30 optics, 8° wide field, rangefinder reticle and focus-free design. The VIVI Voyager 8310C adds a fluorescent mechanical compass and optional tripod support at 575g, while the 570g VIVI Voyager 8310 is the pure lightweight observation model without a compass.
Does the VIVI Voyager 8310 have a rangefinder?
It has a built-in mil-scale rangefinder reticle that supports estimating distances and target sizes by reading the scale — it is a reticle-based estimating tool, not a laser rangefinder.
Can I use VIVI Voyager 8310 binoculars with glasses?
Yes. The 18mm eye relief and folding rubber eyecups let glasses wearers quickly reach a comfortable viewing position with the full field visible.
