Backlit LCD Display Interface
The Bad Elf GPS Pro offers the first Apple approved GPS with an informative
user interface. Prior GPS devices used simple LEDs to indicate status, leaving
the user guessing about status details. The Bad Elf GPS Pro makes it easy for
the user to check location details (latitude, longitude, altitude, heading, speed,
and universal time) directly on the GPS without requiring connectivity to the
iPod touch, iPhone, or iPad. Further information concerning the quality of data
and satellite usage is also available directly on the device. Additionally, users
may check Bluetooth connection status, battery levels, and data log storage usage at a glance. The display also has a backlight for readability at night.

USB Port / ElfPort™
The standard USB mini-B port on the back of the Bad Elf GPS Pro operates
primarily as a standard charging port for recharging the GPS Pro’s internal
battery. This port also supports Bad Elf’s ElfPort™technology, which enables
communication with supported peripheral devices when combined with custom
Bad Elf cables and the enabling software.
Data Storage
The Bad Elf GPS Pro contains 64MB of flash memory for storage of trip data.
At a standard sampling rate of one position recorded per second (1Hz), the
device can store up to 100 hours of trip data. The data can be divided into
separate trips or collected as one single data log. The Bad Elf Utility app readily offloads trip data logs for storage on the Pod touch, iPhone, or iPad. The
data can then be emailed and shared.
Power System
The Bad Elf GPS Pro includes a long life, embedded lithium ion battery. When
both the Bluetooth® radio and the GPS are active, the battery offers up to 16
hours of continuous operation on a single charge. When operating in standalone data logging mode, that is, with the Bluetooth radio OFF, the Bad Elf
GPS Pro can operate for over 30 hours.

Pair an Apple Device with the Bad Elf GPS Pro
The Bad Elf GPS Pro only needs to be paired once with your iPod touch,
iPhone, or iPad. After your Apple device and Bad Elf GPS Pro are paired, they
will connect automatically when both units have their Bluetooth radios ON and
are within range of each other.
To pair the Bad Elf GPS Pro with an iPad, iPhone, or iPod touch, follow these
simple steps:
1. On the Apple device, start the Settings app, then select General > Bluetooth. Make sure Bluetooth is turned ON.
2. This page will then show accessories that are within range and available
for pairing.
3. Turn on your Bad Elf GPS Pro (if it is not ON already).
4. Within 10 seconds, you should see the Bad Elf GPS Pro appear in the list
of devices, with a status of “Not Paired”. Tap this item in the list to start
the pairing process.
5. Within 10 seconds, you should see a dialog on your Apple device offering
a PIN number. This PIN will also be displayed on the LCD display. This
allows both sides of the connection to authorize the pairing with the remote device. Matching the PIN numbers ensures that you can confirm that
you are pairing the correct devices. Data entry is not required.
6. On the Bad Elf GPS Pro, press the GPS Button to authorize the pairing.
On your Apple device, press the “Pair” button.
7. In the Settings app, under General > Bluetooth, you should now see the
Bad Elf GPS Pro listed with a “Connected” status.
Page 7
Up to six (6) Apple devices can be paired and connected to the Bad Elf GPS
Pro simultaneously. Just follow the steps above for each Apple device that you
wish to connect to the Bad Elf GPS Pro.
You can turn Bluetooth off by pressing and holding the Bluetooth button for
3 seconds. While Bluetooth is turned off, the GPS and data logging will still
function, but communications with your Apple device will not be possible. You
can turn Bluetooth on again by pressing and holding the Bluetooth button again
for 3 seconds.
Download the App from the App Store
The Bad Elf GPS Utility app is a free app available in iTunes. The app allows
you to verify the accessory is paired and correctly connected to your Apple device. It shows the raw GPS data being received by the GPS receiver and allows
you to configure the GPS logging features. Once you have logged some trips,
the app allows you to transfer these logs to your Apple device for visualization
and sharing.
Finally, if any firmware updates become available, the app will download them
to your Apple device for installation into the accessory hardware.
After you have paired your Bad Elf GPS Pro to your Apple device for the first
time, you will be prompted to download the Bad Elf GPS Utility app from the
iTunes App Store. If you do not have Internet connectivity, or do not wish to
download the app at that time, you can ignore this prompt. Your Bad Elf GPS
Pro does not require the Bad Elf Utility app to operate with apps and will work
out of the box with any location-based apps you have installed.
Please visit the Bad Elf website ( for recommendations on
compatible apps for various activities such as aviation, marine, fitness, hiking,
running, cycling, geocaching and more. The Bad Elf GPS Pro fits all lifestyles.

satellite signals may take a minutes or more the first time the device is turned
on or after it has been out of use for an extended period of time.
While the Bad Elf GPS Pro is acquiring satellites, the LCD display shows the
number of satellites that are acquired out of the possible satellites in view. Once
a lock is acquired, the LCD display shows speed, heading, altitude, and accuracy. Press the GPS button to cycle through other screens that shows a variety
of other values and data logging status.
Data Logging with the Bad Elf GPS Pro
Press and hold the GPS button for 3 seconds to turn on data logging. Once data
logging is turned on, the LCD display shows a blinking icon along the bottom
of the display. The Bad Elf GPS Pro records your position every second while
data logging is on.
When data logging is on, pressing and holding the GPS button for 3 seconds
causes a prompt to appear. You can then choose either to record a point of interest (POI) and continue data logging or to turn data logging off.
Once data logging is complete, you can use the Bad Elf Utility app to save,
map, share, or delete the recorded trip.
