A GPS receiver triangulates
precise positioning by locking onto high frequency radio waves which are
transmitted from a series of 24 satellites that orbit the Earth. While the
science behind the global positioning system may seem complex, the practical
applications are anything but. Outdoorsmen of all kinds have found countless
uses for this technology and today it is used for precise navigation in the air,
on land, and thankfully for anglers…on the water.
As maps become more and more
detailed more memory is required on GPS units. Lowrance solves this problem by
putting a 20GB hard drive preloaded with detailed mapping and charts into the
Global Map 7600C HD.GPS + WAAS has never looked so good with the super hi-res
Combined with sonar, GPS
technology takes on a whole new level of practical value to anglers. By using
the combination anglers have a tool that allows them to examine underwater
structure, mark fish, and then map that location. While sonar has been utilized
in fishing nearly two decades longer than GPS, the combination of the two
technologies was a match made in heaven. Once considered a luxury, today’s
affordable and easy to use GPS combo units are considered an essential element
of tackle by countless anglers. The benefits of GPS technology transcends just
knowing where you are at any given time.
The 498C Sounder gives you the
cartography you need to venture offshore. These versatile units come ready to
launch with preloaded marine map detail utilizing the new BlueChart® g2
technology. Coverage is for U.S. coastal areas, including Alaska and Hawaii
I remember fishing the Delta
years ago, where every rocky lined cut and slough looked identical. It was easy
to get lost in the miles of waterway, and precious fishing time was wasted
simply by trying to gain our bearings while translating paper maps in an effort
to return to prime fishing spots. GPS mapping improves the fishing experience
each and every time you visit any body of water, familiar or not waterways are
easier to navigate when you know exactly where you are.
Raymarine's A65’s direct sunlight
viewable display and rugged submersible construction make the A65 the perfect
choice for center consoles and open cockpits.
By familiarizing yourself with
the maps beforehand, then entering in waypoints and planning your routes, you
are setting yourself up for success. While less time is wasted trying to reach
your desired destinations GPS units also provide the added benefit of allowing
you to return to the exact same location at a later time.
