Basically what makes the ZD-3HD a decent buy is that it's light enough to carry all day and still picks up DJI stuff and FPV drones across a pretty wide spectrum—the 400MHz to 6.1GHz range handles 1.2G, 2.4G, and 5.8G bands routinely. Most buyers in the field go with the dual-battery option because you get up to 12 hours of runtime (roughly), which is a lot more practical than lugging around a big case.
We've had a few units come back from customers who use them near airports and they've performed well—the false alarm rate is noticeably lower than cheaper fixed-frequency models. It's 261 grams and 120×60×55mm including the antenna, so stashing it in a daypack is straightforward, and the IP54 rating means light rain or dust won't kill it (usually). Detection distance runs 1000 to 3000m but that's enviroment-dependent—real-world tests in open fields give about 2000m, while urban areas drop to 800m or so.
One thing you might not think to ask is that the replaceable battery is a standerd lithium pack, not a proprietary one, so swapping spares costs about $15 each. The three alarm types (visual, audio, vibration) all work simultaneously, but we usually set vibration-only for covert ops since the buzzer is audible. Also, the 1.2G band is better for long-range detection than the 2.4G (typically), but for FPV racing quads you'll want 5.8G active.
Lead time is 20 days or so for a batch of 50 units—we usually have stock, but confirm if you need faster. it come with CE, FCC, and RoHS certs on the COA, and we pack 10 units per carton with foam inserts. No SDS needed for the battery pack, but we include the TDS anyway. This model isn't suited for covert interception—it only detects and alerts, not jams.
Weight. That's teh selling point for mobile teams—261g is lighter than most binoculars, so it's actually easy to forget you're carrying it. For fixed-site installations, a heavier unit with a bigger antenna might give better range, but for patrol work the tradeoff is worth it.
In open terrain you can get up to 3000m, but in dense urban environments with lots of interference, expect closer to 1000m. It really depends on line-of-sight and signal congestion.
Yes, that 261g is the full unit with battery and antenna. It’s light enough to clip on a belt or slip into a jacket pocket without weighing you down.
The unit comes with two rechargeable lithium batteries. One powers the detector while the other charges, giving you up to 12 hours total runtime. You can swap them in seconds.
Absolutely. We provide the original certification copies (CE, FCC, RoHS) with every shipment, so you won’t have issues with import or local compliance checks.
It picks up any signal in the 400MHz–6.1GHz range, including 5.8GHz FPV transmitters. So yes, it’ll catch homemade FPV drones, not just DJI or WiFi types.
