Holy Stone HS175D vs Potensic Atom 2
Specs, camera quality, and ratings compared · Updated 2026
The Atom 2 costs $299 and uses GPS + GLONASS with a 3-axis gimbal and 4K camera. The HS175D costs $170 and uses single-band GPS with electronic stabilization and an overstated 4K camera.
The $129 gap is larger than it sounds because the Atom 2 is a fundamentally different class of drone. It has gimbal stabilization, a Sony sensor, and GPS that locks in half the time.
The HS175D is the cheapest GPS drone that works. The Atom 2 is the cheapest GPS drone that works well.
Pros & Cons
Holy Stone HS175D
- Two batteries included give about 44 minutes of total airtime for $170
- 215 grams stays under the 250g FAA registration threshold
- GPS auto-return works reliably and brings the drone home when battery gets low or signal drops
- Brushless motors are quieter and last longer than the brushed motors on cheaper drones
- Foldable design fits in a jacket pocket, making it easy to carry anywhere
- Wireless controller connection means no phone cable dangling from the remote
- Misleading 4K claim only applies to photos; video maxes out at 2.7K/25fps, and some reviewers only got 1080p files saved to the SD card
- No gimbal and no electronic stabilization means shaky, wobbly footage in anything but dead calm air
- 250-300 meter range in real-world use, nowhere near the advertised 500m
- Holy Stone app has quirks: recording indicators don't always match what actually saves to the card
- 25fps video looks noticeably choppier than the 30fps standard most other budget drones offer
- No RAW photo support, and the small sensor produces muddy colors in anything but bright sunlight
Potensic Atom 2
- Remote ID built in for full FAA compliance
- Strongest non-DJI alternative in the sub-250g class
- PixSync 4.0 transmission with 10km range
- AI Visual Tracking and Night Mode capabilities
- 3-axis gimbal for smooth video
- No geofencing restrictions for total pilot control
- No obstacle avoidance sensors increases crash risk
- ~22 minutes real-world battery life, well short of the rated 32 minutes
- Mobile app is less refined than the DJI ecosystem
- AI tracking can lose subjects behind minor obstacles
- 1/2-inch sensor underperforms DJI's 1/1.3-inch chip in low light
- Build quality feels thinner and more plasticky than DJI equivalents

GPS and Satellite Systems
- Atom 2: GPS + GLONASS with 15-20 second lock times
- HS175D: single-band GPS with 30-60 second lock times
The Atom 2's dual-constellation GNSS locks faster and holds position more accurately.
Camera System
The Atom 2 has a 1/2-inch Sony sensor with a 3-axis gimbal shooting genuine 4K/30fps. 7K).
The gimbal on the Atom 2 produces smooth, stable footage in a different class from the HS175D's shaky EIS output.
Flight Performance and Range
- Flight time: 32 min (Atom 2) versus 23 min (HS175D)
- Range: 4 km via PixSync 2.0 (Atom 2) versus 300m Wi-Fi (HS175D)
- Weight: 249g (Atom 2) versus 213g (HS175D)
The Atom 2's 4km range means you can actually use it for aerial photography rather than flying within shouting distance.
Flight Modes
Both support GPS RTH and basic waypoints. The Atom 2 also has follow-me mode. The HS175D does not.
Choose the Potensic Atom 2 if:
- The extra $129 fits your budget
- You want real 4K with gimbal stabilization and a Sony sensor
- You need 4km range for actual aerial photography
- Follow-me mode is part of your workflow
- You want 32-minute flights without constantly watching the battery
Choose the Holy Stone HS175D if:
- $170 is the ceiling and the budget won't stretch to $299
- Camera quality is secondary to having GPS and RTH
- You only fly within 200-300 meters
- You want the cheapest GPS drone that works
- You're buying a practice drone you expect to replace within a year
Our Verdict
The Atom 2 at $299 if you can stretch the budget. The GPS and camera quality jump is substantial for $129 more. The HS175D at $170 if the budget won't flex. It's a real GPS drone at a price where most alternatives are WiFi toys.
