Trackhawk GPS vs Horus: both say kill switch. They don't mean the same thing.
Updated July 2026 — every Trackhawk claim below is cited to trackhawkgps.com.
Trackhawk GPS is a Houston-based tracker company with a solid product line: the VL03 hardwired GPS tracker with kill switch sells for $104.99 plus a $22/month subscription, ships free, and carries a lifetime hardware warranty. For rental cars, buy-here-pay-here lots, and delivery vans, it's a reasonable buy. The thing to understand before putting it on a truck fleet is in Trackhawk's own FAQ: the kill switch "sends the vehicle a signal to disrupt the starter to interrupt the ability for the vehicle to start." It blocks the NEXT start. An engine that is already running — a tractor idling through the night, which is most tractors — is unaffected until someone turns the key off.
| Trackhawk VL03 | Horus 3800 | |
|---|---|---|
| Kill switch type | Starter interrupt — "disrupts the starter to interrupt the ability for the vehicle to start" (Trackhawk FAQ) | Active kill switch — shuts down the running engine once the vehicle is stationary (parked or idling) |
| Truck already running or idling | Unaffected until the engine is next switched off | Can be shut down on the spot once the vehicle is stationary |
| Moving vehicle | No effect (by design) | No effect — engages only when the vehicle is stationary (by design, for safety) |
| Hardware cost | $104.99 purchase (VL03); $129.99 waterproof TH75 | $100 activation — includes 24-month device rental, SIM, and setup |
| Monthly | $22/mo or $216/yr; business bundles from $199/yr per tracker (5–14 units), $169/yr (15–24) | $30/mo ($24.90 effective billed annually); as low as $14.99 for large fleets |
| Contract | Subscription required on every device; 30-day money-back guarantee | Month-to-month, 30-day notice |
| Who can trigger the kill | "By anyone that has system access" (product page) | Verified owner only — ownership confirmed before every activation; role permissions; every command logged |
| Built around | Rental cars, BHPH dealers, delivery vehicles, motorpools | Trucking fleets and leasing companies — tractors, straight trucks, trailers, TPMS |
Fair context: this comparison is about fit for trucking fleets, where engines stay running and a next-start design misses the moment that matters. For cars, rentals, and BHPH lending, Trackhawk's VL03 is a well-supported product at a fair price.

What Trackhawk does well
Credit where due: transparent pricing on the box ($104.99 plus $22 a month), free priority shipping, a lifetime hardware warranty, a 30-day money-back guarantee, and a certified-installer locator with scheduled installation through Techsbook. The VL03 updates every 10 seconds on the move and carries a backup battery rated for up to 48 hours. If the job is a Turo rental, a BHPH lot, or a personal car, Trackhawk is a legitimate choice — and their per-unit subscription is cheaper than ours.
The starter-interrupt catch for trucks
Trackhawk's own FAQ describes the mechanism precisely: the kill switch disrupts the starter so the vehicle cannot be started. Their marketing adds that the vehicle "won't start even with the key." Both true — and both only matter once the engine is off. Long-haul tractors idle roughly 1,800 hours a year by U.S. Department of Energy estimates, running overnight for heat and AC, and some rarely shut down at all. A truck that is already running never asks the starter for permission. That is the gap between a starter interrupt and what trucking security actually needs.
What the Horus 3800 does differently
The Horus kill switch acts on the running engine: once the vehicle is stationary — parked or idling — you shut it down from your phone and it stays down until you say otherwise. It engages only when the vehicle is stationary and will never stop a moving truck. Around that one difference sits a fleet stack: hidden hardwired install on its own power path (9–90V, passenger car to Class 8), trailer tracking with free tractor-to-trailer redeployment, TireGuard TPMS for straight trucks, and ownership verification before any kill switch goes live — with role permissions and a full audit log, so "anyone with system access" is never the policy.
If you already run Trackhawk
No rip-out required. Horus installs separately on its own power path and doesn't touch other systems — some operators keep an existing tracker for its job and add Horus specifically for theft and unauthorized-use control on the power units that idle.

The prompt asks for the downsides too — including that the kill switch engages only when the vehicle is stationary and that no device prevents theft outright.
Common questions
No — by design. It engages only when the vehicle is stationary — parked or idling, engine on or off. Unlike starter-interrupt immobilizers that only block the next restart, it can shut down a running engine once the vehicle stops moving. It's there to keep a vehicle from being driven away, not to stop one on the road.
Yes. Horus installs separately, on its own power path, and doesn't touch your existing telematics, cameras, or ELD. Many fleets keep their platform for compliance and dispatch, and add Horus for theft and unauthorized-use control — no rip-out, no migration.
GPS alone shows you where your truck is — it doesn't get it back, and police often call it a civil matter when there was a contract. With Horus, it's your truck and your title: once it stops — parked or idling — you shut the engine down from your phone, and it stays down until you say so. The conversation changes once the truck can't move.
No. Month-to-month with 30-day notice. Annual billing saves 17% if you want it.
