In a bison tube vs film canister geocache matchup the bison tube wins. Its aluminum body and O-ring keep logs dry for years while a film canister's snap on lid cracks and lets water in over time.
Film canisters cost less and hold more swag but bison tubes survive rain, sun and rough hides far better.
Bison Tube vs Film Canister Geocache: Key Differences at a Glance
Same basic job, different lifespans. Both hold a logbook and little else but the gap shows the moment weather gets involved.
Bison tube vs film canister at a glance
| Feature | Bison Tube | Film Canister |
|---|---|---|
| Waterproofing | O-ring seal, stays dry for years | Snap lid only, leaks as it ages |
| Material | Anodized aluminum, rust resistant | Thin plastic, cracks in UV and cold |
| Typical cost | $1.25 and up per tube (Space Coast Geo Store, 2026) | Often free to reuse or a few cents in bulk |
Both push difficulty up simply by being small and easy to miss. A camouflaged bison tube hanging in foliage often earns a tougher rating than a film canister tucked in a crevice, though.
Bison tubes come from geocaching specialty shops and outdoor retailers. Film canisters are harder to buy new now that photo film is rare. Most cachers reuse an old one or grab a reproduction from a geo supply store.
Which One Should You Choose
Choose Bison Tube if…
- You're hanging the cache from a branch, fence or bolt with the attached keyring
- The hide sits somewhere exposed to rain, snow or direct sun
- You want a container that survives years without replacing
Choose Film Canister if…
- You need a wider container for a rolled log or a tiny trackable
- The hide is tucked in a dry, sheltered spot like a stump hollow or ledge
- Cost matters more than lifespan and you already have one on hand
Bottom Line
Weather exposure, mainly. Choose the bison tube for anything outdoors or long term, and save the film canister for dry, low traffic tuck-ins. That's the real call on bison tube vs film canister geocache: match the container to how wet the hide gets.
