Jump into the product cards below, then verify current retailer terms before you buy.
This research-based guide compares published power, mounting, location, alert, subscription, and app requirements for two ShadowGPS products. It is not a hands-on security test, and a tracker cannot prevent theft or guarantee recovery.
Check consent, law, and coverage
Use tracking devices only on property and vehicles you are legally permitted to monitor. Confirm local law, cellular coverage, subscription terms, battery expectations, installation location, and the effect of signal conditions before purchase.
Choose by power source
An OBD-II model may suit a compatible vehicle when continuous vehicle power and visible port placement are acceptable. A rechargeable asset tracker may suit non-vehicle property, but it requires a charging routine and an appropriate mounting surface. Verify every feature with the manufacturer.
