Description
After more than a decade of daily use by thousands of falconers worldwide in extreme conditions, the next generation GPS has been obsessively engineered with your feedback in mind.
The new GPS Pro has a smarter design: With active intelligence built into the new GPS2 transmitter, it handles real-time decisions automatically—managing modes, conserving power, and adapting to variables resulting in much longer battery life and peace of mind for extended recoveries.
GPS Pro keeps your birds secure on your own private network while giving trusted friends access when a search calls for more help. Machined from titanium for greater durability and precision, every detail of GPS Pro was designed to reduce anxiety in the field and bring a new sense of confidence for every flight.
LET’S ANSWER YOUR QUESTIONS!
+ WHAT IS NEW?
- Smart Battery with intelligent sensor fusion doubles battery life from 2-3 days to 4-5 days
- New IDLE Mode conserves power when the bird is still
- New Live EXT Mode extends life using Live-trackable 5-second updates
- New PING feature quickly confirms bird’s position without mode change
- New titanium case, smaller, and stronger
- Precise remaining battery life reported as a percentage
+ HOW DOES IT WORK?
GPS Pro 10: Â track up to 10 birds

GPS Pro 20: track up to 20 birds
Ideal for bird shows, zoos, raptor centers, and abatement projects.
optional Ten-Battery PowerTower charging station fully charges 10 batteries using internal power.

+ HOW DOES IT WORK WITHOUT CELL SERVICE?
Direct RF connection – not dependent on nearby mobile towers, so it can be used anywhere in the world without fear of “dead zones”. No SIM card to maintain therefore no waterproofing issues or further costs from text requests, etc. required to operate it. Simple. Reliable.
The Marshall GPS Pro System can work anywhere in the world! If you are using your system outside of cell coverage or in spotty coverage areas, you can download the maps of your favorite hunting spots to use offline.
Real-time GPS updates – not delayed or irregular response waiting for an SMS. You see where your bird is now, not just where it was.
+ ITEMS TO ADD TO YOUR SYSTEM
Why would you want to add the additional UHF receiver to your system?
The Field Marshall UHF receiver allows you to track the beeping signal of your GPS2 transmitter when you are in “Plan B Mode”. It’s also needed to track your backup UHF regular telemetry receiver.*
*Marshall always recommends flying with two transmitters. A long-life traditional telemetry transmitter complements the GPS Pro system perfectly.
Why would you want to add the additional UHF Omni High Gain Antenna?
The use for the Omni high gain antenna when attached to the Pocketlink, will boost the range 2-3 x that of the standard PocketLink field antenna.
The PocketLink Pro uses an SMA connector for quick attachment to Marshall’s High Gain UHF Omni antenna.
+ WHAT IS THE BATTERY LIFE?
What is the typical battery life of the GPS2 transmitter?
The user-configurable modes available within AeroVision allow the GPS2 transmitter to run for up to a week on a rechargeable battery. You can mix the modes to be configured for several hours of high-update GPS plus many hours of lower update rate tracking. Default settings the battery life is 4-5 days, double that of the blue Turbo GPS.
What is the typical battery life of the Pocketlink?
The PocketLink Pro’s internal lithium battery provides 10+ hours of runtime. Charged via USB-C. The internal battery has built-in intelligence and has no “memory”, allowing you to leave it plugged into the vehicle at all times to stay “topped-off” and ready for field use.
+ WHAT IS THE TYPICAL RANGE?
Free space range varies by terrain, elevation, and obstacles. On average you should expect:
- GPS2 Data Tracking Range: 2 to 100 miles*
- RF “Beeping” Tracking Range: 5 to 200 miles**
*Measurements of distance are quoted using the optional High Gain Omni antenna; varies depending on terrain, bird’s height above ground, and obstacles.
**When tracking traditional “beeping” telemetry signal using the Field Marshall UHF Direction Finding Receiver.
+ WHAT IS AEROVISION PREMIUM?
AeroVision Premium Features (iOS) (available vis In-App Purchase) $10.99/month or $98.99/year.
AeroVision Premium Features (Android) (available vis In-App Purchase) $8.99/month or $79.99/year.

+ WHAT ARE THE MOUNTING METHODS?
The Marshall GPS Pro System can easily swap mounts from Tail to back, leg, or neck mount right in the field. Learn more about the different mounting methods.
+ HOW DO I REMOVE THE TAIL SPRING ON GPS TRANSMITTER?
All transmitters come with a tail spring.
To remove, untwist the antenna protector. There is a silver washer holding the spring. Pull the spring and washer downwards, wiggle back and forth till the washer and spring break free. After removing the spring, re-install the washer and antenna protector. Save the spring to easily convert your transmitter for a tail/Trackpack use in the future.
