3. Understanding GPS
What is GPS and how does it work?
Your Sureshotgps™ Hero 150x uses the Global Positioning System [GPS] to work out
how far you are from the front, centre and rear of each green. The system relies on
the Sureshotgps™ 150x receiving signals from orbiting GPS satellites.
How long does it take to gain reception from the satellites?
Always turn your Sureshotgps™ 150x on for at least ve minutes before you wish to
use it.
Can I use my Sureshotgps™ 150x inside the home or ofce?
Your Sureshotgps™ 150x will not generally gain reception inside. For best accuracy,
your Sureshotgps™ should have an unimpeded view of the sky.
When playing, what position is best for accuracy of my Sureshotgps™ Hero
150x?
You should clip your Sureshotgps™ 150x to a position on your buggy or bag that
maximises clear view of the sky. A range of accessories are available such as cart
mount kits and pull cart kits on www.sureshotgps.com.
GPS accuracy is affected by a number of factors, including satellite positions, noise in
the radio signal, atmospheric conditions, and natural barriers to the signal. Noise can
create an error between 5 to 10 meters and results from static or interference from
something near the receiver or something on the same frequency.
The most accurate determination of position occurs when the satellite and receiver
have a clear view of each other and no other objects interfere.
How do I Check for GPS Signal?
Before checking, ensure you have maximum clear sky above and the Sureshotgps™
Hero 150x has been on for at least ve minutes.
At the top of the main screen on the right there is a satellite icon.
When it is solid [not ashing] you have good satellite strength.
