There are hundreds of GPS tracker models on the market and the choice can feel overwhelming. The good news: the right device for your fleet is usually obvious once you understand three things — how the tracker is powered, how it talks to the platform, and which sensors it carries.
The three main tracker categories
1. Hardwired trackers
Best for: permanent fleet installations, commercial vehicles, school buses.
- Wired into the vehicle's electrical system
- Can detect ignition on/off, read fuel level, monitor doors
- Hidden installation discourages tampering
- Needs a qualified installer (1–2 hours per vehicle)
2. OBD-II plug-and-play
Best for: quick deployment on light vehicles and saloons.
- Plugs into the diagnostic port under the dashboard
- Self-installable in under a minute
- Picks up vehicle diagnostics automatically
- Easier to remove (a pro for quick rotation, a con for security)
3. Battery-powered / portable trackers
Best for: trailers, generators, high-value tools, temporary tracking.
- No installation required
- Battery life ranges from weeks to several years
- Limited features compared with hardwired
- Ideal for assets that do not have a permanent power source
Features that actually matter
Update frequency
- Real-time (10–30 seconds) — best for active dispatch and high-value cargo
- Periodic (1–5 minutes) — fine for most fleets, lower data cost
- Daily check-in — only suitable for asset location confirmation
Connectivity
- 4G/LTE cellular — works almost everywhere in Tanzania, monthly data needed
- Dual-SIM — automatic failover when one network drops out
- Satellite (rare) — for cross-border or remote operations
Sensors and add-ons
- Fuel level sensors (essential for trucks)
- Temperature probes (cold-chain logistics, pharmacy)
- Door open/close sensors
- Driver ID / RFID
- Panic / SOS button
Matching device to vehicle
| Vehicle type | Recommended tracker | |--------------|---------------------| | Delivery vans | OBD-II or hardwired | | Heavy trucks | Hardwired + fuel sensor | | School buses | Hardwired + driver ID + panic button | | Construction equipment | Hardwired + engine-hours sensor | | Trailers and assets | Long-life battery-powered | | Boda-boda / motorbikes | Compact hardwired with backup battery |
Common mistakes to avoid
- Buying the cheapest tracker without checking platform support. A device that does not speak your platform's protocol is useless.
- Skipping installation quality. Loose wiring causes false ignition events and ruined nights of data.
- Forgetting the SIM strategy. Plan data bundles, voice (for SMS commands), and renewal reminders before you go live.
- Buying for today's fleet, not tomorrow's. Pick a tracker with room to add fuel or temperature sensors later.
