transducer, mount the bracket onto the hull as shown
on the right.
Make sure to position the transducers so they are level
in both the fore and aft and side to side direction so
they will look straight down. Check the location of
your boat's waterline and position the flat top surface
of the transducer so that it is parallel to the waterline as
shown below.
Note: If the transducers are not mounted so that the
fore and aft direction is parallel to the surface, then the
forward looking display may be distorted where flat
bottoms appear to be slanted upwards or downwards.
After mounting the transducer and actually using the
Twinscope on the water, you may need to readjust the
transducers' mounting for optimum performance.
