Overview: The Garmin Approach S4 is a wrist-worn golf GPS unit combined
with a lightweight sports watch. Its memory is loaded with distance information for
more than 30,000 pre-loaded golf courses worldwide. The S4 uses a high-sensitivity GPS receiver to measure individual shot
distances and track how far you walk on the course. No subscriptions or setup fees are required. The Approach
S4 is compliant with USGA rules.
Display: The Approach S4 has a 1" diameter monochrome
high-resolution touchscreen LCD with a resolution of 128 x 128 pixels. The display's Hole View indicates the number of the hole being
played, the distance to the back, center, and front of the green, and the par
for the hole. On-screen icons display a low battery warning, GPS use, and alarm
active indication. The display can be set to black on a white
background or white on a black background.
Included Maps: The Approach S4 has CourseView map
data loaded in its built-in flash memory. The data contains distance information
to the front, back, and center of the greens for more than 30,000 golf courses
worldwide. Lifetime free course updates are available from the Garmin website,
and can be downloaded from your PC to the Approach S4 using the supplied
USB/charging cradle. Installed CourseView maps include:
- CourseView Medium Americas 3.90
- CourseView Medium Europe, Middle East & Africa 3.50
- CourseView Medium Australia/NZ 3.00
Functionality: The Approach S4 initially takes 30-60 seconds
to acquire satellite signals and determine your location. As you play, the unit automatically updates your position, giving you the exact yardage to the
front, center, and back of the green. Because pin placement varies, you can
touch and drag the pin to the day's location. You can also measure the distance of
a particular shot. For Par 4 and 5 holes, you can view a list of layup and
dogleg distances. During the round, you can save and label up to five locations, such as water hazards or bunkers,
on each hole. Distance units can be set to yards or meters.
Digital Scorecard: During your round, you can enter your
score by entering + or - the number of strokes over or under par. Your total
score (relative to par) is updated as each hole's score is entered. If
necessary, you can select any previously played hole to change the score for
that hole. You can also record statistics, such as number of putts taken and
number of fairways hit, during the round. Before you start the round, you can select Stroke Play or Stableford
scoring. (Stableford points are awarded as specified by the USGA.) At the end of
your round, you can connect the Approach S4 to your computer to view and save
Touchscreen and Button Controls: The S4 lets you maneuver
through the menus and settings by touching the screen. Different than most
mobile devices, the touchscreen is designed so you can operate it with your
fingertip or while wearing gloves. It is optimized to prevent accidental touches
while you play, requiring a firm press to select items or change pages. The unit has
four buttons on the sides and two touch sensitive icons on the perimeter of the
- Power/Light Button: for turning on the backlight
(single press), and for turning the
device on or off (press and hold)
- Measure Button: for measuring the distance of a shot
- Score Button: to enter your score for the hole
- Green View: to view the green with distances to front
and back and pin placement
- Menu Icon: to open the menu for the current screen
- Return Icon: return to the previous screen
TruSwing: The optional Garmin
TruSwing golf swing sensor mounts to your club, and pairs to the Approach S4 via
Bluetooth Low Energy (BLE). TruSwing provides swing metrics to see how your
mechanics affect ball flight and shot results. It measures your swing tempo and
speed, face to target, dynamic loft, shaft angle, club path and coordinates, and
shaft lean. After your shot, the swing measurements are displayed on the S4 so
you can instantly analyze the shot.
Watch: In addition to its GPS functions, the Approach S4 is
a digital watch. By default, the watch time is set automatically when the device
acquires satellite signals. You can also set the time manually. The watch also
has an alarm, and can display 12-hour or 24-hour time formats.
Odometer: The Approach S4 has a built-in odometer to
measure your total time and walking distance as you play the round. The odometer
automatically starts and stops when you start or end a round. It can also be
started or stopped manually, as well. You can turn the
odometer off, if you desire.
Smart Notifications: The S5 can connect wirelessly to
your iPhone via Bluetooth 4.0, and will alert you when you receive a text, email, or RSS alert.
The S5 utilizes Bluetooth Smart to wirelessly sync with smartphones running the
Garmin Connect Mobile App. Smart Notifications let you read texts and emails directly on the
Approach S5. Smart Notifications can be received on iPhone 4s, 5, 5c, 5s, 6, 6
Plus, iPad Air, iPad 3, iPad 4, iPad mini, and iPod touch (5th generation)
running iOS 7.0 and above. Compatible Android phones (running OS 4.3 and above)
include HTC One (M7), LG Flex, Sony Xperia Z2, and Samsung Galaxy Note 2, Note
3, S3, S4, S4 Active, and S5.

Power Requirements: The Approach S4 operates on a rechargeable Lithium-ion, coin cell battery. In the GPS mode, a fully charged
battery should give you up to 10 hours of continuous use while playing golf. The Power Save mode
turns off the GPS receiver after a period of inactivity, and displays only the
time and date. If you are using the unit in the Power Save mode continuously, a
fully charged battery should provide up to 6 weeks of battery life. Using the S4
as a watch with Bluetooth notifications, the battery should last approximately
Battery Charging: The unit comes with a snap-on charging
cradle/USB cable. You can charge the battery
by plugging the cable into your
computer's USB port.
Waterproof: The Approach S4 is waterproof to withstand immersion in
up to ten meters of water. You can wear the watch in the rain with no worries.
Optional Carrying Case: To protect your Approach S4 when not
in use, Garmin offers an accessory
carrying case. The zippered case can hold the watch, AC adapter, and
