It may suit an owner who already has a working unit, but anyone considering a used one should account for its limited GPS runtime, splash-only water protection, aging-battery uncertainty, and security updates that ended in 2019.
This review separates what Fitbit documented when the Surge was new from what buyers should verify on a used device. The available research does not establish current used prices, present-day syncing reliability, or independent GPS and heart-rate accuracy results.
Fitbit Surge features at a glance
| Feature | What the documentation says | What to keep in mind |
|---|---|---|
| GPS | Built-in GPS; Fitbit listed pace, distance, elevation, split times, route history, and workout summaries. | Fitbit’s published estimate was up to five hours of GPS use. Wait for a GPS signal before starting an activity. |
| Heart rate | Optical wrist-based heart-rate tracking, including during exercise. | The dossier contains no independent controlled accuracy results. |
| Activity tracking | Steps, distance, calories, active minutes, sleep quality, floors, and heart rate. | Stored data includes minute-by-minute records for the most recent seven days and daily summaries for 30 days. |
| Connected features | Caller ID, text alerts, and mobile music control. | These are basic phone-connected functions, not a full smartwatch app ecosystem. |
| Battery | Fitbit’s manual says seven days or more without GPS workouts; its 2015 cycling announcement says up to five hours with GPS. | These are original manufacturer estimates, not a promise about a used watch with an aged battery. |
| Water protection | Fitbit describes the Surge as splash proof. | The manual says not to shower or swim with it. |
| Security updates | Google’s Fitbit security table lists minimum updates through September 2019. | This date documents security-update support, not whether every app or syncing function works today. |
What the Fitbit Surge was designed to do
Fitbit introduced the Surge as its “Fitness Super Watch,” combining built-in GPS, wrist-based optical heart-rate tracking, activity monitoring, and a small set of connected-watch functions. Fitbit’s launch announcement described GPS-derived pace, distance, elevation, split times, route history, and workout summaries, as well as caller ID, text alerts, and mobile music control. These are manufacturer-described capabilities, not independent performance findings.
The product manual lists a three-axis accelerometer, altimeter, GPS receiver, Bluetooth 4.0 radio, vibration motor, optical heart-rate monitor, ambient-light sensor, gyroscope, and magnetometer. It also describes tracking steps, distance, calories, active minutes, sleep quality, floors, and heart rate.

GPS and exercise tracking
The Surge has built-in GPS, so its original design did not require a phone for GPS-based outdoor exercise tracking. Fitbit listed pace, distance, elevation, split times, route history, and workout summaries. Its 2015 announcement of outdoor cycling tracking also described ride distance, duration, average speed, heart rate, and calories, with route and elevation details available in the app or web dashboard.
Fitbit’s manual advises waiting for a GPS signal before beginning an activity. If you start moving before the watch acquires GPS, it may estimate the initial distance from step count, which can affect the start of the route and distance record. The dossier does not establish independent accuracy results, so claims that the Surge is accurate or inaccurate relative to other watches would go beyond the available evidence.
Battery life and charging
Fitbit’s manual estimates seven days or more of use without GPS workouts. Fitbit’s 2015 cycling announcement gives up to five hours of GPS use and also describes 168 hours of general heart-rate use. These are manufacturer estimates for the product, not guarantees for a device that has been used or stored for years. A TIME reviewer reported seeing “five or so days” on a review unit in 2015; that is one reviewer’s observation, not a forecast for a used Surge.

The manual says a full charge takes one to two hours and describes charging with a cable connected to the port on the back of the device. For a replacement cable, confirm that the listing explicitly states compatibility with the Fitbit Surge/FB501; current availability has not been verified.

Water resistance: splash proof, not swim proof
Fitbit’s manual calls the Surge splash proof and specifically says not to shower or swim with it. Do not treat it as waterproof or suitable for swimming workouts. This is an important limitation for anyone buying a fitness watch primarily for pool use.
Phone features and support status
The Surge’s documented connected features include caller ID, text alerts, and mobile music control. They are a small set of companion features rather than the functions of a modern app-based smartwatch. The research does not confirm how reliably these features or Fitbit app syncing work with current phones, so check the particular watch and phone before relying on them.
Rank #3
- Provides an excellent solution if you want to personalize your Surge or just replace the broken band. This replacement band perfectly fits for Fitbit Surge

Google’s Fitbit security-support table lists minimum security updates for the Surge through September 2019. That is the documented end date for its listed security updates; it does not, by itself, prove that all app, account, or sync functions have stopped working.
Who should consider a Fitbit Surge?
- Existing owners: If your Surge still works for your needs, its documented built-in GPS and exercise tracking may remain useful.
- Used-device buyers: Consider it only if you can verify the specific unit’s condition, charging cable compatibility, and the phone features you intend to use.
- Swimmers: Avoid it for swim tracking; Fitbit’s manual says not to swim or shower with it.
- Buyers seeking current security support: Note that Google lists minimum security updates through September 2019.
What to check before buying used
- Ask the seller to demonstrate that the watch powers on, charges, and records an activity.
- Confirm that the included or replacement charging cable explicitly fits the Surge/FB501.
- Check that the watch acquires a GPS signal before starting an outdoor activity, as the manual recommends.
- Verify whether the phone-connected functions you need work with your own phone; current compatibility is not established by the research for this review.
- Do not buy it for swimming or shower use.
Verdict
The Fitbit Surge’s defining capabilities are clear: built-in GPS, wrist-based heart-rate tracking, activity monitoring, and basic phone-connected features. Its practical appeal as a used device depends on the condition of that particular unit, especially its battery and charging cable, while the documented security-update history and splash-only water protection are important limitations.
Recommended Free Tools
It is best approached as an older fitness watch whose original feature set is documented, not as a current smartwatch or a proven accurate training instrument. The available evidence does not support a broader recommendation based on present-day prices, competing models, or independently tested performance.
