VIVI Voyager 8310C 8×30 HD Compass Binoculars
VIVI Voyager 8310C 8x30 HD compass binoculars add a full navigation toolkit to the lightest chassis in the Voyager family. Weighing just 575g — only 5g more than the compass-free 8310 — they carry a fluorescent mechanical compass for dim-light heading reads, a mil-scale rangefinder reticle for estimating distances and target sizes, and the same wide 8° field of view that makes the 8x30 platform a scanning favorite.
Product Description
The VIVI Voyager 8310C 8×30 HD compass binoculars add a full navigation toolkit to the lightest chassis in the Voyager family. Weighing just 575g — only 5g more than the compass-free 8310 — they carry a fluorescent mechanical compass for dim-light heading reads, a mil-scale rangefinder reticle for estimating distances and target sizes, and the same wide 8° field of view that makes the 8×30 platform a scanning favorite.
The optics combine a BAK-4 Porro prism with FMC multi-layer coating for a vivid, high-contrast image with faithful color and stable depth. Focus-free operation means the view is sharp the instant you raise the binoculars, and 18mm eye relief keeps long watches comfortable for glasses wearers.
Sealed dustproof, waterproof and fogproof, the VIVI Voyager 8310C is ready for orienteering, hunting, search-and-reserve sweeps and field surveying in changing weather. Where the reticle tells you how far, the compass tells you which way — a complete lightweight direction-finding package.
Direction and Distance in One View
The fluorescent compass and mil-scale reticle appear together in the field of view, so you can log bearing and estimated distance to a target in a single, uninterrupted observation.
Compass Capability at 575g
Full compass binocular performance at just 575g supports fast-moving navigation, hunting and rescue work where every gram in the pack counts.
Tripod-Ready When You Need a Fixed Post
Optional tripod support lets you set up a stable observation point, while the focus-free optics stay sharp for handheld work on the move.
Why Choose the VIVI Voyager 8310C?
The VIVI Voyager 8310C is the direction-finding model of the 8×30 Voyager pair. It exists for users whose observation questions are not just “what is that?” but also “which way and how far?” — navigators, orienteers, hunters and survey crews who need a bearing as often as a clear view.
Compared with its sibling, the VIVI Voyager 8310 8×30 HD Compact Rangefinder Binoculars, the 8310C adds two working tools for a negligible 5g: the fluorescent mechanical compass readable in dim light, and optional tripod support for fixed observation posts. If your tasks involve routes, bearings or extended stakeouts, those additions earn their weight many times over.
Both models share the same optical core — 8×30 configuration, 8° wide field, BAK-4 Porro prisms, FMC multi-layer coating and focus-free operation — so you are choosing between capability sets, not image quality. Choose the VIVI Voyager 8310C for navigation and direction work; choose the VIVI Voyager 8310 for the simplest, lightest pure-observation package.
Product Features
- Fluorescent Mechanical Compass: The built-in compass glows in dim light, providing readable headings at dusk, dawn and under canopy.
- Rangefinder Reticle: The mil-scale reticle supports estimating distances and target sizes, pairing naturally with compass bearings for complete target logging.
- 8×30 Optical Configuration: 8x magnification with 30mm objectives delivers vivid, detailed viewing in a compact, light body.
- Lightweight 575g Build: Compass capability at just 575g supports all-day carry for navigation, hunting and rescue tasks.
- Focus-Free Operation: No focusing system to adjust — the optics deliver an instantly sharp image for immediate decision-making.
- Wide 8° Field of View: A 120m field at 1000m helps you acquire landmarks, game and subjects quickly across open terrain.
- BAK-4 Porro Prism: BAK-4 glass renders stable, naturally three-dimensional images with accurate depth perception.
- FMC Multi-Layer Coating: Fully multi-layer coated optics maximize transmission and contrast for crisp views in varied daylight.
- 18mm Eye Relief: Comfortable eye relief supports glasses wearers through extended navigation and observation sessions.
- Waterproof, Fogproof & Dustproof Construction: Sealed housing protects the compass and optics through rain, spray and dust.
- Optional Tripod Support: Tripod mounting (optional) enables stable hands-free observation from a fixed position or hide.
- Diopter Compensation: A -5 to +5 D diopter range matches the binoculars precisely to your eyesight.
Application Areas
Orienteering and Land Navigation
The fluorescent compass and wide 8° field let you confirm bearings to landmarks quickly, while the mil-scale reticle supports estimating leg distances along your route.
Hunting
At 575g, the 8310C carries easily all day, and the compass plus reticle combination helps hunters plan stalks, log game movement and relocate downed animals.
Search and Rescue
Crews can scan terrain through a wide 120m@1000m field, then report both bearing and estimated distance to finds — coordinates-ready information under time pressure.
Field Surveying and Mapping
Compass headings and mil-based distance estimates support preliminary field reconnaissance and feature documentation before instrument setup.
Coastal and Small-Boat Navigation
The waterproof, fogproof and dustproof construction and luminous compass make the 8310C a practical backup navigator for kayakers and small-boat operators.
Security and Patrol Observation
The focus-free optics and compass help patrol officers record direction of movement, while optional tripod support covers static post observation.
Hiking and Trekking
The light chassis and 165 x 75 x 115mm footprint stow easily, keeping a full navigation-observation instrument available on any route.
Outdoor Education and Scout Groups
The visible compass and reticle scales make the 8310C an instructive tool for teaching map reading, bearings and distance estimation in the field.

FAQ
Are VIVI Voyager 8310C binoculars waterproof?
Yes. The 8310C features waterproof, fogproof and dustproof construction, protecting both the optics and the compass mechanism in wet field conditions.
What is the field of view of the VIVI Voyager 8310C?
The VIVI Voyager 8310C provides a wide 8° field angle, equal to 120m at 1000m, making it easy to acquire landmarks, game and moving subjects.
Can the VIVI Voyager 8310C be mounted on a tripod?
Yes. The specifications list optional tripod support, which is useful for stable, hands-free observation from a fixed post, hide or vehicle.
How much do VIVI Voyager 8310C binoculars weigh?
They weigh 575g — only 5g more than the compass-free VIVI Voyager 8310 — keeping full compass capability comfortable for all-day carry.
What is the difference between the VIVI Voyager 8310C and the VIVI Voyager 8310?
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; the 570g VIVI Voyager 8310 omits the compass for the simplest lightweight observation package.
Does the VIVI Voyager 8310C have a rangefinder?
It has a built-in mil-scale rangefinder reticle that supports estimating distances and target sizes by scale reading — it is a reticle-based estimating tool, not a laser rangefinder.
Can I use VIVI Voyager 8310C binoculars with glasses?
Yes. With 18mm eye relief and folding rubber eyecups, glasses wearers can reach a comfortable eye position and still see the compass and reticle scales clearly.
