For car enthusiasts and everyday drivers alike, keeping a close eye on vehicle health is paramount. In the world of automotive diagnostics and monitoring, the Scangauge Obd2 has long been a respected name. But with the rise of Bluetooth OBD2 scanners and smartphone apps, is the Scangauge still a relevant and superior choice? This article dives into a detailed comparison, drawing insights from real user experiences, to help you decide which OBD2 monitoring solution is best for your needs.
Understanding Scangauge OBD2 and Bluetooth Alternatives
The discussion around vehicle monitoring often boils down to two main types of devices: dedicated OBD2 gauges like Scangauge and Bluetooth OBD2 adapters that pair with smartphone apps. Both connect to your car’s OBD2 port, providing access to a wealth of real-time data about your vehicle’s performance and health.
Scangauge OBD2 devices are standalone units designed specifically for displaying vehicle information. They typically mount on your dashboard or steering column and offer a constant, real-time view of selected parameters.
Bluetooth OBD2 scanners, on the other hand, are adapters that plug into the OBD2 port and wirelessly transmit data to a smartphone or tablet. These rely on apps like Torque Pro or BlueDriver to display and interpret the data.
Scangauge OBD2: The Dedicated Monitor
Scangauge has built a solid reputation for being a reliable and user-friendly OBD2 monitor. Its primary appeal lies in its simplicity and always-on functionality.
Pros of Scangauge OBD2:
- Always-On Monitoring: One of the most frequently cited advantages of Scangauge is its dedicated nature. As one user, jht3, mentions, “Unlike a phone, I don’t have to worry about turning it on, batteries charged, or having the gauges up and monitoring. It’s always monitoring”. This “set it and forget it” approach, as LC4LIFE puts it, is a major convenience for many.
- Ease of Use: Scangauge is designed for straightforward operation. Users like LC4LIFE highlight its simplicity for “monitoring temps super easy, clearing codes super easy, getting accurate mph super easy.”
- No Phone Dependency: For those who prefer to minimize phone use while driving, or simply want a dedicated device, Scangauge offers a phone-free solution. Francis K expresses this sentiment clearly: “I would much rather have everything in front of me at all times rather than have to check my phone…and I try to be on my phone as little as possible.”
- Reduced Clutter (for some): While some argue Scangauge adds clutter, others like LC4LIFE counter that “Either way you are adding another device in the cab whether it’s a Scangauge or phone.” For users already using their phone for other functions, a separate device might actually reduce on-screen clutter on their phone.
Cons of Scangauge OBD2:
- Cost: Scangauge units typically have a higher upfront cost compared to basic Bluetooth OBD2 adapters.
- Limited Features Compared to Apps: While Scangauge excels at real-time monitoring, it may lack the advanced features and customization options offered by smartphone apps like Torque Pro. ppc points out that “Torque Pro has so much more information that can be displayed on a single screen in a more readable format than a Scangauge.”
- Installation (Wiring): While mounting is generally considered easy, as White Sheep demonstrates with a picture of a neatly mounted Scangauge, the wiring might be seen as slightly more involved than simply plugging in a Bluetooth adapter.

Bluetooth OBD2 Scanners: Leveraging Smartphone Power
Bluetooth OBD2 scanners have gained immense popularity due to their affordability and feature-rich capabilities when paired with smartphone apps.
Pros of Bluetooth OBD2 Scanners:
- Cost-Effective: Bluetooth OBD2 adapters are generally much cheaper than dedicated devices like Scangauge. As KC masterpiece notes, “You can get a good obd2 dongle for $15 on Amazon and I think the app is around $30.”
- Feature-Rich Apps: Apps like Torque Pro and BlueDriver offer a wide array of features, including customizable dashboards, data logging, performance testing, and advanced diagnostics. ppc emphasizes the greater information display capacity of Torque Pro.
- Versatility: Using a smartphone app opens up possibilities for integrating vehicle data with other phone functions like navigation and music, as mentioned by jpoole: “I use my phone for navigation so it’s on a mount and visible all of the time. If/when I’m interested in monitoring temps/etc. I can pull up torque and run it on that same phone.”
- Less Clutter (for some): For users who already rely heavily on their smartphones in their vehicles, using a Bluetooth OBD2 scanner can minimize additional devices and wires, leading to a cleaner dashboard. jpoole prefers it “mostly because it’s less clutter.”
Cons of Bluetooth OBD2 Scanners:
- Phone Dependency: The biggest drawback is the reliance on a smartphone or tablet. As Francis K points out, you need to “make sure I have my phone with me, the app has to be open,” and ensure the phone is mounted and charged.
- Potential for Distraction: Constantly checking a phone screen for vehicle data can be more distracting than glancing at a dedicated gauge, especially if using the same phone for navigation or other apps.
- Initial Setup: While generally straightforward, setting up a Bluetooth OBD2 scanner and app might require a bit more initial configuration than a Scangauge.
- Data Privacy Concerns: As Kernal raises an important question: “Does anyone know what information the Torque Pro app collects from your phone ie: silently in the background?”. Users should be mindful of app permissions and data privacy when using smartphone-based solutions.
Real-World User Preferences: Scangauge OBD2 vs. Bluetooth Scanners
The forum thread provides valuable insights into how real users weigh these pros and cons. Many users, particularly those focused on monitoring critical parameters like engine temperature in older vehicles (like the Toyota Land Cruiser 80 series mentioned by Fisher67 and arndog123), favor the Scangauge for its always-on reliability and simplicity.
Users like White Sheep, LC4LIFE, arndog123, and clx16 all showcase their Scangauge installations, often mounted on the steering column for easy visibility. This placement, as described by jht3, prioritizes critical data like “Coolant temp and an accurate MPH.”

Conversely, users like jpoole and KC masterpiece advocate for Bluetooth OBD2 scanners and apps like Torque Pro, citing lower cost, more features, and less clutter, especially when leveraging a smartphone already in use for navigation and other in-car functions. ppc even suggests using a “cheap android tablet” to mitigate phone dependency while still enjoying the benefits of app-based solutions.
Making the Right Choice: Scangauge OBD2 or Bluetooth Scanner?
The best choice between Scangauge OBD2 and Bluetooth OBD2 scanners depends largely on individual needs and preferences.
Choose Scangauge OBD2 if:
- You prioritize always-on, dedicated monitoring.
- You prefer simplicity and ease of use without relying on a smartphone.
- You want a robust and reliable standalone device.
- Cost is less of a concern than dedicated functionality.
Choose a Bluetooth OBD2 Scanner and App if:
- You are budget-conscious.
- You want a feature-rich and customizable monitoring solution.
- You are comfortable using your smartphone or tablet for vehicle monitoring.
- You want to minimize dashboard clutter and integrate vehicle data with other phone functions.
Ultimately, both Scangauge OBD2 and Bluetooth OBD2 scanners offer valuable tools for vehicle health monitoring. By considering your priorities and weighing the pros and cons of each, you can select the OBD2 solution that best fits your driving needs and preferences. Whether you opt for the dedicated reliability of a Scangauge or the versatile functionality of a Bluetooth scanner, staying informed about your vehicle’s condition is a smart move for any driver.
