The Edge is the first Garmin device to incorporate the new-generation SiRFstarIII(TM) architecture, a platform offering extremely high performance and sensitivity from SiRF Technology Holdings, Inc, a leading provider of GPS- enabled location technology. The SiRFstarIII architecture provides a rapid time to first fix, enabling cyclists to determine and track their location -- even under challenging conditions such as heavy foliage or "urban canyons" created by city skyscrapers.

The Garmin Edge 305HR heart rate monitor uses a robust wireless technology that eliminates cross-talk and interference and delivers real-time heart rate data exclusively to the user's device. This data is stored with each track point for post-workout analysis. Compared to the Forerunner 301, the Edge 305HR heart rate monitor uses a new softer, more comfortable strap design.

Customizing the Edge is achieved using several innovative features:

-- Workouts: Design workouts with multiple steps based on time, distance,
calories or heart rate. Establishes workout targets based on speed,
calories, cadence and heart rate (only Edge 305CAD and 305HR,
respectively).
-- Virtual Partner(TM): Team up with a virtual training partner that
provides continuous feedback. Depicts a digital cyclist (desired pace)
in relation to the user's real-time pace and notifies if ahead or
behind desired pace.
-- Courses: This innovative new feature allows you to race against a
recorded course and match previously set speeds at every point of the
way, or navigate a brand new route. Combine the Courses and Virtual
Partner(TM) features and race an opponent that varies speed while
climbing hills and navigating tricky turns.
-- Bike Computer: Customizable Bike Computer screen shows up to eight
different data fields. The user may customize the display for the size
and placement of the data.
-- Auto Pause(TM): Pauses the timer when the user's speed drops below a
pre-set threshold.
-- Alerts: Program alerts to sound if the user strays outside the range
of speed, heart rate, or cadence values. Alerts can also indicate when
a set amount of time or distance has passed.

Although the Edge is completely self-contained, Garmin's PC-based Training Center software puts the Edge ahead of the pack by helping users plan and analyze their workouts. Users may create their own workouts or use workout templates that can be downloaded into the unit for any level of personal training. It also offers interactive analysis tools that let the user chart their performance. Speed, heart rate, cadence, elevation, and pace may be graphed all at once or individually. As with other Garmin fitness products, the Edge may be used with MotionBased.com, a unique internet-based performance analysis and mapping tool for GPS and heart rate information. Endurance athletes may use the Edge with TrainingPeaks.com, an easy-to-use web based training system designed to help athletes train for any event.

Different Versions:


There is also the Garmin Edge 305CAD, it is exactly the same as the Garmin Edge 305HR, but with a few differences:

The Edge 305CAD incorporates a self-calibrating, wireless speed/cadence sensor that mounts to the rear chain stay of the bicycle, in addition to the primary unit that mounts on the stem or handlebars of the bicycle. Like the heart rate monitor, the speed/cadence sensor uses the same robust wireless technology that eliminates cross-talk and interference. The 305CAD is self- calibrating and easy to install.
