WARNING
Navigation based solely on one method or
one instrument should never be practiced.
While the Color Twinscope can be quite
useful in showing underwater structure and
changing bottom conditions both below and
in front of your vessel, there are many
situations and conditions which can cause
erroneous or distorted readings.
In addition, there are many situations that
can cause "blind spots" in the Color
Twinscope's field of view including the
presence of temperature inversion layers
(thermoclines), water turbulence, and high
concentrations of suspended particles in the
water.
While the Color Twinscope can be
considered as a useful aid to navigation, it
should never be the only means of
navigation.
