Released on October 19, 2023, the Garmin Xero C1 Pro offers a compact, no-frills solution for gathering ballistic data in the field. Built to withstand rough conditions and provide reliable readings without extra setup gear, it immediately appeals to professionals and enthusiasts who prioritize mobility and simplicity. The question is whether this chronograph can hold up under real-world use where consistency, durability, and speed matter most.
The Garmin Xero C1 Pro chronograph has overall dimensions of 3.03″ (L) × 2.38″ (H) × 1.36″ (W) and features an outer case made from fiber-reinforced polymer, a composite plastic commonly used for its balance of strength and weight. The housing, screen interface, and button points are sealed to meet an IPX7 water-resistance rating, allowing the device to function after submersion in up to one meter of water for up to 30 minutes.
The front of the Xero C1 is minimal in appearance, displaying only the “Garmin” logo. This understated design is intentional, as the device’s Doppler radar sensor is positioned directly behind the front face. This sensor allows the Xero C1 to measure projectile velocities with an accuracy of ±0.1% for rifles and pistols, and ±0.4% for slower projectiles, such as arrows or airgun pellets.
Both sides of the device are relatively plain, with the exception of the USB-C port located on the left side, that is protected by a rubberized cover. This port is used for charging the built-in, non-replaceable rechargeable lithium-ion battery rated at 3.7 V. When fully charged, the battery provides approximately six hours of continuous operation.
The rear of the Xero C1 features a 240 × 320 pixel monochrome display that clearly presents all settings, shot data, and status information. This transflective screen is designed for visibility in a wide range of lighting conditions, including direct sunlight. Users can adjust the brightness across multiple levels to suit their environment, and there is an option to invert the color scheme—switching between dark text on a light background and light text on a dark background—to enhance readability. Additionally, the display surface has a matte finish that helps minimize glare and reflections, further improving visibility during outdoor use and reducing eye strain.
The top of the Xero C1 has four buttons for navigating the device’s menu system. These include an “OK” button, which functions as an enter or select key; a “back” button used to return to the previous menu screen, which can also be held for five seconds to power the device on or off; and “up” and “down” arrow buttons to move the highlighted selection within the menu.
The bottom of the Xero C1 features a 1/4″-20 threaded female adapter for attaching the included tripod. The tripod is constructed from lightweight plastic and provides a base width of approximately 5 inches when fully extended.
The Xero C1’s onboard software provides the primary interface for configuring device settings, including display preferences, units of measurement (e.g., feet per second, meters per second), and measurement parameters within the Settings menu. It also guides users through the setup and management of shooting Sessions, offering a clear, real-time shot display during data collection. The chronograph connects via Bluetooth Low Energy to Garmin’s ShotView smartphone app, which is compatible with both iOS and Android devices. The app enables users to review and analyze recorded shot data after each session, with data syncing occurring quickly once the devices are in range. Within the app, users can edit or delete individual shots, add contextual notes, and export the full dataset as a CSV file for further analysis or record-keeping. This integration streamlines data management and facilitates detailed performance tracking over time.
The Garmin Xero C1 Pro chronograph is only available in a coyote desert tan, and comes with the included tripod, USB-C cable, and documentation.
Product Evaluation Scores:
- Cost – Good (4/5): At an MSRP of $599, the Garmin Xero C1 Pro chronograph delivers a significant leap forward in ballistic measurement technology by combining compactness, precision, and ease of use into a single, highly portable unit. Unlike legacy systems—such as the bulky and tripod-dependent LabRadar ($366) or the Velociradar ($604.99) from Caldwell, both of which have faced criticism for unreliable software, inconsistent performance in varied lighting, and setup complexity—the Xero C1 Pro integrates next-generation Doppler radar technology in a form factor small enough to fit in a pocket. It operates independently of external lighting or projectile path alignment, providing consistent velocity data with minimal setup time for up to 6 hours (more if an external battery pack is used). In contrast, budget-oriented options like the ProChrono DLX Bluetooth ($159.99) from Competitive Electronics or Caldwell Ballistic Precision 2.0 ($164.99) rely on optical sensors that must be positioned downrange—placing delicate equipment in harm’s way and requiring additional hardware to operate effectively. Garmin’s Xero C1 Pro eliminates these issues entirely, offering a fully enclosed, self-contained unit with intuitive smartphone integration, ruggedized construction, and multi-shot tracking—making it not only safer and more convenient, but a far better value proposition in terms of performance-per-dollar in today’s chronograph market.
- Comfort – Good (4/5): The Garmin Xero C1 Pro chronograph offered a notably streamlined and user-friendly experience in the field, largely due to its compact size, straightforward design, and practical interface. Weighing very little, the device fit easily into a pack or jacket pocket, which benefits users who prioritize portability. Unlike traditional chronographs that often require multiple components, external sensors, or alignment tools, the Xero C1 Pro required minimal setup—end-users simply unfolded the included tripod, powered the unit on, and began recording data. The rear display, a matte-finished monochrome screen, remained readable in various lighting conditions, and allowed for brightness adjustment and screen inversion to accommodate user preference. The four-button layout on the top of the unit supported basic navigation, with functions that were intuitive and responsive during use. The smartphone app helped streamline post-session data management without the need for additional devices or software.
- Durability – Good (4/5): From a durability standpoint, the Garmin Xero C1 Pro consistently proved resilient under extended field use. Its fiber-reinforced polymer housing handled routine use, accidental drops, bumps, and exposure to rain without issue. Its IPX7 water-resistance rating (submersion up to one meter for 30 minutes) further ensured protection in wet conditions. Even when placed in close proximity to the rifle’s muzzle, the unit reliably absorbed shock and maintained accurate performance. One of the few concerns regarding long-term durability is the non-user-replaceable internal lithium-ion battery. While it is rechargeable via USB-C, replacement requires Garmin service or technical disassembly, which voids the warranty. However, discussions on forums such as SnipersHide forum have shown that the Garmin battery (Garmin part number 361-00056-15) can be replaced manually, provided it includes an integrated battery management system (BMS) board—though this is an unofficial, user-driven solution. Garmin support representatives stated the battery is rated for three years of continuous use, with an expected service life of up to four years in high-use scenarios or around ten years with intermittent use. Importantly, even if the internal battery fails, the Xero C1 is designed to operate when connected to an external power source via its USB-C port. This fallback ensures the unit remains functional, even beyond the lifespan of the built-in battery—offering added reassurance for long-term users who rely on its consistent field performance. Users should note that mounting the Xero C1 directly to a rifle’s handguard—particularly with rigid aluminum brackets—has led to occasional (though rare) unit failures. Garmin has clarified that the device is not shock-rated for that level of impulse and was never intended for direct weapon mounting. As such, damage from this setup is considered misuse and is not covered under warranty.
- Functionality – Good (4/5): From a functional perspective, the Garmin Xero C1 Pro was designed around a streamlined interface and integrated software intended to simplify the process of capturing and managing ballistic data. Its onboard menu system, accessed through just four physical buttons, allowed the user to configure measurement units, display brightness, and interface settings without relying on additional hardware. The transflective monochrome screen had a matte finish that remained readable in varying lighting conditions, with an option to invert the color scheme for user preference. The Xero C1 also paired with Garmin’s ShotView app via Bluetooth easily and consistently. This app provided access to stored shot data, session history, and allowed users to annotate, delete, or export individual shot strings. Exported data could be exported as CSV files for use in spreadsheets or performance tracking. The synchronization between the chronograph and app was typically quick and required no cables or manual data transfer. While the device was functional on its own, most advanced data management features—such as reviewing detailed shot logs or exporting sessions—were only accessible through the app. The Xero C1 (nor its associated app) did not include built-in ballistic calculators or support for custom projectile profiles, which could limit its utility for some users who require in-depth analysis directly from the device or via their smartphone. Additionally, the software interface focused on delivering core functionality, without extensive onboard customization or expanded features beyond basic data logging and display. Overall, the Xero C1 Pro emphasized ease of use and efficient data handling, providing a simplified workflow for capturing velocity data. For users seeking a portable chronograph with minimal setup and basic digital integration, it offered a focused set of features designed to streamline the process of recording and reviewing ballistic information. It should be noted however, that Garmin did not include any type of nylon carrying case or container to transport the Xero C1 in, and it will be on the consumer to find a suitable alternative.
- Weight – Excellent (5/5): Weighing just 3.7 ounces for the device and 5.7 ounces with the included tripod, the Garmin Xero C1 Pro has a total system weight of only 9.4 ounces. This reflects a modern, lightweight design made possible by Garmin’s use of compact Doppler radar technology and a streamlined, all-in-one form factor that eliminates the need for additional sensors or bulky components. In contrast, older chronograph systems are significantly heavier and often more cumbersome to deploy. The LabRadar, for instance, weighs 3.8 ounces for the device alone but requires multiple accessories for full use. Caldwell’s VelociRadar weighs 48.7 ounces, the ProChrono DLX Bluetooth from Competition Electronics comes in at 33.6 ounces, and Caldwell’s Ballistic Precision 2.0 weighs 20.4 ounces. These legacy models rely on older optical or radar-based systems that typically involve external sky screens, tripods, or chronograph arms—adding bulk and setup time. By comparison, the Xero C1 offers a more portable, integrated solution that is easier to carry and deploy, particularly in field conditions where space and time are limited.
Overall Rating – Good (21/25)
