Example: If a 30-degree Y angle is requested, the
60 degrees (that is the angle from the default position).
5 Since the transducer is pointing straight forward, the
0 (zero).
Example 2
For purse seine with the gear on the starboard side, the transducer must be pointed
approximately 90 degrees towards starboard with the indicator arrow pointing up. To
set the angles correctly, observe this exercise. Use your cellphone to visualize the
transducer movements.
1 Start with the transducer in its default position: The transducer face is horizontal
facing down, and the indicator arrow is pointing straight forward.
2 If the transducer is properly installed without unintentional skew, the
can also be set to 0 (zero).
Around X
3 Lift the front end of the transducer up, so that the indicator arrow moves up. This
is a Rotation Around Y.
4 Proceed until the requested angle has been reached.
Example: If a 15-degree Y angle is requested, the
75 degrees (that is the angle from the default position).
5 From this raised position, turn the transducer towards starboard. The indicator
arrow is still pointing up. This is a Rotation Around Z.
6 Proceed until the requested angle has been reached.
Example: If a 90-degree Z angle is requested, the
90 degrees (that is the angle from the forward position).
Example 3
Used for purse seine with the gear on the port side, the transducer must be pointed
approximately -90 degrees towards port (or 270 degrees towards starboard which
puts you in the same direction) with the indicator arrow pointing up. To set the
angles correctly, observe this exercise. Use your cellphone to visualize the transducer
movements.
1 Start with the transducer in its default position: The transducer face is horizontal
facing down, and the indicator arrow is pointing straight forward.
2 If the transducer is properly installed without unintentional skew, the
can also be set to 0 (zero).
Around X
3 Lift the front end of the transducer up, so that the indicator arrow moves up.
4 Proceed until the requested angle has been reached.
Example: If a 20-degree Y angle is requested, the
70 degrees (that is the angle from the default position).
