The bottom drawer at the branch has eleven chargers and four trackers. The register says thirty were issued this quarter. Two went to Guwahati on a market truck and stopped pinging somewhere after Siliguri. One came back in a driver's bag three weeks later with a flat battery. Nobody is sure where the rest are, and the person who signs for them is tired of being asked.
Our view: a disposable GPS tracker is not a cheaper tracker. It is a decision that, on this lane, the trip back costs more than the device. Make that decision lane by lane, with your own return rate, and the argument in the branch goes away.
A disposable tracker is defined by the trip it does not make
Strip away the packaging and a disposable GPS tracker looks a lot like a reusable portable one. It is a battery device that goes in the cab or on the load, reports position over the mobile network and, on better units, temperature and humidity too. The difference is what happens at the destination. A reusable device is collected, charged and sent out again. A single-use device is closed with the trip and taken out of service.
So the useful question is not which device is better. It is which costs less per trip once you count everything that happens after the truck arrives.
The return trip is the hidden cost of a reusable tracker
A reusable tracker looks cheap on the purchase order because the price is spread over many trips. That only holds if it comes back. Getting it back has its own costs:
- someone at the destination has to take it out of the cab and keep it safe;
- it has to travel back to a branch that will send it out again, by courier or on a return truck;
- it sits on a charger before it is ready, so you need more devices than trucks in transit;
- and some never return, because the truck was hired, the driver changed or the consignee had no reason to care.
On a closed loop between your own plant and your own depot, these costs are small. Your people are at both ends. On a one-way load to a dealer three states away, on a market vehicle you will never see again, they are large, and the last one dominates. Our device recollection playbook covers how to keep that loss low where collection does make sense.
Return rate decides the maths, not the price tag
Here is a worked example. The figures are illustrative, not a price list. Say a reusable device costs ₹6,000 and collecting it costs ₹150 a trip in staff time and courier. A single-use device costs ₹1,500 a trip.
If a share of devices is lost on every trip, the average reusable device lasts 1 ÷ (loss rate) trips. Its cost per trip is the device price divided by that, plus the collection cost.
| Lane | Devices returned | Average trips per device | Reusable cost per trip | Single-use cost per trip |
|---|---|---|---|---|
| Plant to own depot | 90% | 1 ÷ 0.10 = 10 | 6,000 ÷ 10 + 150 = ₹750 | ₹1,500 |
| Plant to distributor, hired truck | 75% | 1 ÷ 0.25 = 4 | 6,000 ÷ 4 + 150 = ₹1,650 | ₹1,500 |
| One-way market vehicle, far state | 60% | 1 ÷ 0.40 = 2.5 | 6,000 ÷ 2.5 + 150 = ₹2,550 | ₹1,500 |
Break-even is where 6,000 ÷ trips + 150 = 1,500, which is about 4.4 trips per device. That means a return rate of about 78%. Above it, reusable wins. Below it, single-use wins. Your own numbers will differ, but the shape will not. Device price matters less than the share that comes back.
The cheapest tracker is not the one with the lowest price. It is the one that does not need a second journey.
Some lanes should be disposable, and some never should
Once you see the return rate as the driver, the choice sorts itself by lane, not by company policy.
| Lane type | Likely choice | Why |
|---|---|---|
| Closed loop between your own sites | Reusable | Your people collect it at the far end, so the return rate stays high |
| Regular lane to a large customer with a dock team | Reusable, if the customer will hand it back | Return is possible but depends on someone else |
| One-way load on a hired or market vehicle | Single-use | Nobody at the far end has a reason to return it |
| Export or very long haul where the device would sit for weeks | Single-use | Return transit and charger time cost more than the device |
| Short, repeated urban trips | Reusable | Many trips per device and an easy return |
Most shippers end up with both. That is why we think the device type should be set on the trip, not bought as a fleet-wide standard. In Portable GPS Tracker, a disposable or reusable GPS tracker for hired trucks, devices can be single-use, with battery for up to 10 days, or reusable and collected at arrival, chosen by lane. Inventory shows each device by branch with battery and last position.
Single-use still needs the same trip discipline
A disposable device is not a way to stop caring about the trip. What happens at the gate decides whether it is useful. The trip still needs the vehicle, carrier, LRs and route attached, so a ping means something to the desk. The customer still needs a tracking link. Cold-chain loads still need a temperature band set from the shipment type, so an excursion is caught while the truck is moving and not read from a logger after delivery.
Two checks matter more for single-use devices. First, the battery has to outlast the trip with room to spare, including the halt at the border or the two days waiting to unload. Second, a device that goes silent must be flagged to a person. It may be a dead battery, or it may be a truck that has left its route. If you are still weighing devices against fixed GPS on owned trucks or phone-based tracking, our comparison of portable GPS vs fixed GPS vs SIM tracking sets them side by side.
The fair objection: throwing electronics away should bother you
The strongest argument against disposable trackers is not cost. It is waste. Every single-use device is a battery and a circuit board that ends its working life after one trip. A logistics head who has spent a year on packaging waste is right to wince at that.
We take the objection seriously, and it points to three practical rules. Use single-use only where the return rate really is low, not because collection is a chore. Treat the used devices as electronic waste, sent through an authorised channel, and check your obligations under India's e-waste rules with your EHS team. Keep raising the return rate on lanes that sit near break-even, because each point above it moves those lanes back to reusable. A good recollection process is the greenest tracker there is.
What to do this week
- Pull last quarter's device register and work out the return rate for each lane, not for the company.
- Put your own device price and collection cost into the break-even sum above.
- Mark each lane as reusable, single-use or borderline.
- For borderline lanes, name one person at the destination who hands devices back, and measure again in a month.
- Check that every trip, whatever the device, has a customer link, a battery check and a silent-device alert.
The drawer at the branch will never be perfectly full. It does not need to be. Each lane needs to run on the device its return rate can afford, and that is a decision you can make in an afternoon. For more on tracking hired trucks, see the Portable GPS Tracker guides.
