iTrail GPS Logger Magnetic Case

The magnetic case is what turns an iTrail logger into something you can actually deploy. The logger itself is tiny — that is its whole advantage — but a tiny device with no mounting is a device that ends up on a roadside. The case adds magnets and weather protection while keeping the smallest footprint of any GPS data logger available.

Mounting: what actually holds and what actually gets a fix

Two requirements pull in opposite directions, and understanding the tension is the whole skill.

Retention wants a flat, clean, ferrous surface with as much magnet contact as possible. Frame rails and flat structural members hold; curved panels, plastic trim, aluminium and composite body parts do not hold at all. Road vibration works a poorly seated case loose over days, not hours — so wipe the surface before mounting, and seat the case flat rather than at an angle.

Signal wants sky. GPS is a weak signal from orbit, and steel above the unit blocks it. Metal below the case is fine; metal above it is the problem. A case buried deep inside a chassis under heavy structure will struggle for a fix no matter how well the magnets hold.

The workable compromise is a flat ferrous surface toward the outside of the vehicle, shielded from direct road spray and stone strike, with as little steel as possible between the unit and the sky.

Also a small secure container

The same case stores a spare key, cash or a small valuable, magnetically mounted out of sight. Worth knowing before you buy one only for tracking.

Read this before you place anything on a vehicle

Placing a tracker on a vehicle you do not own or have authority over is a crime in many states and exposes you to civil liability in most of the rest; Arizona has its own statute on electronic tracking. Marriage is not an exception, and an employee’s personal vehicle is a different question from a company vehicle that employee drives. Company-owned assets, your own vehicles, and consenting adults are the clear ground. Anything else is a question for an attorney before the case goes on, not after — and if the answer is that you cannot place it yourself, a licensed investigator may be able to obtain what you need lawfully. See private investigations.

The other side of this

If your concern is finding a device someone may have placed on your vehicle, see RF and GPS bug detection — and note that a recovered tracker should go into a Faraday bag rather than being switched off, so it stops reporting without alerting whoever placed it.
