This handbook describes the following HD Series Fishfinders:

L770D Plus
L770DRC Plus

L1260DRC Plus
Raymarine HD Series Fishfinders use the latest processor and sonar
technology for accurate performance and echo detection. Units feature 7" or
10.4" daylight viewable color LCD displays and the Raychart (RC) models
include a full C-Map NT/NT+ Chartplotter.
L770D/RC Plus and L1260D/RC Plus Fishfinders come packaged with a
DSM250 Sounder Module, which provides digital echo sounder image data
via
hsb
dynamically from very wide to very narrow, as required by the actual water
and seabed conditions. This provides superior fish discrimination and bottom
structure details in conditions where other fishfinders, which have a fixed
bandwidth, see very little or nothing at all. The DSM250 employs a very high
transmission repetition or "ping" rate which, along with the digital adaptive
high sample rate receiver, ensures that the entire water column is presented in
superb detail and optimal color allocation.
HD Series Fishfinders feature dual frequency (200 kHz and 50 kHz) operation
and—depending on the transducer installed and conditions—up to 1000 watts
RMS output power and performance from 3 ft (1m) up to 5000 ft (1700 m).
Use the High Speed Bus (
integrated system with additional devices, such as Pathfinder Plus Radar,
Raymarine Autopilot, and Raystar Wide Area Augmentation System
(WAAS) GPS products.
