Humminbird HELIX 7 SERIES User Manual

Xtreme Depth Sonar
(HELIX XD GPS)
The HELIX XD GPS Fishfinder uses the XD
transducer to provide extreme depth coverage with
DualBeam PLUS technology.
The Xtreme Depth sonar beams can be operated at
two frequencies: 50 kHz (74°) and 200 kHz (20°). T he
wide, 50 kHz beam transmits at a low frequency to
provide greater depth coverage, up to 2500 ft (762 m).
The narrow, 200 kHz center beam transmits at a high
frequency to provide maximum detail at shallower
depths.
The DualBeam PLUS technology allows you to view
the sonar returns blended together, separately, or
side-by-side (see Sonar Menu Tab: Beam Select and
Views for more information).
Depth capability is affected by such factors as boat
speed, wave action, bottom hardness, water
conditions, and transducer installation.
