A large, 4.5 inch wide LCD display offers a clear view of all readouts. Both the
display and the operating keys are backlit for easy nighttime operation.
Latitude and longitude are given in large numbers, and are also easy to see in
all conditions. Use the GP-270ML to translate LORAN TD coordinates to GPS
coordinates. Altitude (feet/meters), accuracy (feet/meters), speed (nautical
miles/knots, statue miles/mph or kilometers/kph), course heading, date and time
are also all clearly displayed. Five "soft" keys below the display are
software driven and offer easy, on-screen control of important GPS functions.
Controls are adjustable to give readout information in English, Dutch, French,
German or Spanish.
Features unique to a GPS at this price point include a full 10 key keypad, a
convenient 24-hour tide prediction feature for up to 2,500 tide stations, and a
local-time sun and moon rise and set feature that also includes moon phase
readouts for each hour of the day. It's easy to use the GP-270ML for cruise
Also unique are the GP-270ML's marine databases, with 16,000 pre-programmed
points. Up to 100 more user-programmable points may be added. The large LCD
offers an impressive plotting display, allowing present position and previous
track to be plotted with lights, buoys and waypoints. Waypoint names are
user-programmable. The track is automatically recorded, and previous tracks can
be stored in memory for future use. Paths can be manually followed or
automatically followed with an autopilot.
For safety, a man-overboard feature may be activated which saves the person's
last known position. Audible alerts may be added to the visual alerts given for
waypoint arrival, crosstrack error, border crossing, anchor watch and avoid
points. A quick-response start up time offers you a first fix well within a
minute (and much faster still if the GP-270ML has already been operated earlier
in the day) and stays accurate through rapid acceleration or deceleration (up to
