As the table shows, the DRG69 and DRG70 are nearly identical in size and weight. Both feature extremely compact and lightweight designs making them easy to mount on any vehicle.
There are several differences between the two models when it comes to the electronics and sensors.
The DRG70 has Bluetooth 5.0 which provides a longer wireless range and faster data transfer speeds compared to Bluetooth 4.0 in the DRG69.
Internal storage gets a bump up from 16GB to 32GB in the newer DRG70 as well.
For tracking capability, both models deliver fast sample rates and can record speeds up to 299 mph.
However, the DRG70 clearly pulls ahead in performance with a 30 Hz sample rate, triple the 10 Hz rate of the DRG69.
This allows the DRG70 to take measurements 30 times per second, resulting in more granular and detailed tracking.
The DRG70 also includes support for Galileo satellites in addition to GPS and GLONASS. With more satellites available, the DRG70 can achieve faster and more consistent satellite locks in challenging conditions. Acceleration metrics are identical between the two, but the DRG70 adds over 25 more discrete measurements for comprehensive performance testing.
Overall, while the DRG69 still offers superb tracking capability, the upgraded specs of the DRG70 make it the superior choice for precision and detail. For most users, the extra features will be well worth the slightly higher price.
Key Differences Between Dragy DRG69 And DRG70 GPS Performance Meters
- Ease of Use
One area where the DRG69 and DRG70 are matched is in user-friendliness. Dragy built both models for intuitive operation right out of the box.
Installation takes just seconds – simply mount the meter on the vehicle, connect to smartphone via Bluetooth, and start the app. The rugged, waterproof housing means the Dragy unit can be placed virtually anywhere exterior. Strong 3M adhesive ensures it stays put.
Operation is just as simple. The app features automatic data recording and run logging. Just drive as normal and the Dragy handles all the measurements seamlessly in the background. Easy touchscreen controls allow marking run segments or laps.
Data syncing is a cinch with Bluetooth connectivity. The app provides live-display of performance metrics as they are measured. Results can be reviewed during or directly after a run.
Dragy also includes handy built-in tools like a 0-60 timer that flashes red until the vehicle has accelerated to 60 mph. This visual indicator allows drivers to perfect their launches.
For users who want to dive into the raw data, Dragy allows export via CSV and email. But for most, the intuitive app provides all the analysis tools needed to quantify and improve performance.
With these advanced telemetry systems, accuracy is paramount. Here the tight tolerances and rigorous testing from Dragy pay dividends.
Both the DRG69 and DRG70 deliver consistent, repeatable measurements run after run.
Speed, acceleration, braking distance – all specs can be trusted to be within a 2% margin of error.
This near-perfect precision gives drivers total confidence in the performance readings.
This level of accuracy comes from several key factors.
First is the use of industrial-grade GPS sensors that lock onto satellites rapidly and hold a strong signal.
Augmenting this is the accelerometer that tracks G forces and movement in all axes.
Dragy calibrates the accelerometer perfectly across a wide spectrum before each run.
Advanced algorithms crunch the acceleration and GPS data to calculate key metrics like 0-60 mph in just 0.01 second increments. The system self-corrects measurements on the fly to eliminate sensor drift.
The result is professional-level tracking that rivals expensive, dedicated telemetry equipment.
For drivers, the accuracy means performance gains can be measured precisely. Changes to mods, tuning, or technique can be quantified to the exact hundredth of a second. This allows meaningful comparisons between runs to determine what adjustments are truly improving acceleration, speed, and lap times.
- Track Capabilities
As compact modules, both the DRG69 and DRG70 bring race-level telemetry to amateur and professional track drivers. Their small form factors make them easy to mount in any car, bike, or powersports vehicle.
The DRG70 does gain an edge for track use with the 30Hz sampling rate and multi-satellite locking. At high speeds, the faster update rate keeps measures ultra-precise, while more satellites ensure signal lock is never lost on long curves.
Key track features include:
- Standalone operation – no smartphone required while driving
- Loop recording – memory ring continuously records data
- Multiple vehicles – store data for different cars or bikes
- Laps and segments – log sector and lap times
- Race mode – optimized sampling for racing conditions
After a track session, the Dragy app makes it simple to break down times by lap, segment, and vehicle. Graphical analysis tools showcase acceleration, braking force, and cornering loads. There is even support to overlay video for comparison.
For amateur racers, the telemetry provides concrete data to analyze performance. Tuning adjustments and driver modifications can be refined to shave tenths off lap times. Pros can use the Dragy units for detailed track recon, finding the optimal racing line.
Engineers designed both the DRG69 and DRG70 to handle the stresses of performance driving. The sealed housing provides complete protection from dust, water, vibration, and temperature extremes.
All interior electronics get further shielding to block interference from other vehicle systems and EM sources. The rugged casing allows the Dragy devices to be mounted in the engine bay or passenger cabin without issue.
Constructed from tough polycarbonate plastic, the housing easily survives scrapes and bumps from track use. The 3M adhesive keeps the module secured in the optimal position. For additional protection, silicone cases are available as an accessory.
The long-life battery enables the DRG70 to run for a full 7 hours – ample time to handle extensive road trips or track days. While device operation is nearly maintenance-free, the battery can be easily replaced if needed.
Thanks to this durable build, both units accumulate thousands of trouble-free miles. Their compact profile makes them easy to permanently install and forget. The toughness matches the precision tracking capability.
