The DJI Mini 3 Pro was DJI's benchmark sub-250g drone before the Mini 4 Pro — 249g, 1/1.3-inch sensor, 4K/60fps 10-bit, tri-directional obstacle sensing, and vertical shooting orientation for social media content.
| Sensor | 1/1.3-inch CMOS |
| Max Video | 4K/60fps 10-bit HDR |
| Obstacle Sensing | Tri-directional (forward, backward, downward) |
| Transmission | DJI O3 |
| Weight | 249g (under Transport Canada registration threshold) |
| Flight Time | 34 minutes |
| Vertical Shooting | Yes — sensor rotates for portrait orientation |
| Wind Resistance | Level 5 (38 km/h) |
"The sub-250g advantage for flying in Canada is huge. I can fly recreationally in so many more places without the advanced certification."

"Vertical shooting mode is legitimately useful. My Instagram Reels look so much better than when I was cropping horizontal footage."

"Image quality punches way above its size. You'd never guess a 249g drone could produce footage this clean."

Tri-directional sensing leaves side vulnerability…
Tri-directional sensing leaves the sides unprotected — flying near trees, wires, or buildings requires constant attention to lateral clearance, which the Mini 4 Pro's omnidirectional system handles automatically.

Mini 4 Pro is now similarly priced and more capable — buyers should compare current prices, as the newer model's omnidirectional sensing and O4 transmission often justify the small premium.

DJI O3 transmission range and interference resistance is lower than O4 — in congested urban areas, the video feed can degrade at distances where O4 would remain stable.
Source: YouTube (Drone Supremacy)The Mini 3 Pro is still an excellent drone, particularly if you find it priced significantly below the Mini 4 Pro. The 249g weight advantage for Canadian recreational flyers is real and valuable. However, if prices are close, the Mini 4 Pro's omnidirectional obstacle sensing and O4 transmission are meaningful upgrades. Check current pricing before deciding.
