Graph Tab
The Graph tab enables you to determine the appearance of the

The following settings are available:
• Fish sets how the Fishnder interprets suspended
targets and background information. If you select a sh
symbol, the Fishnder identies some returns for you by
replacing them with sh symbols (in large, medium, and
small sizes based on the size of the sonar return). If you
are using dual beam, sh symbols from the narrow beam
(directly underneath your boat) are solid, and the returns
from the wide beam (out to the sides of your boat) are
hollow.

return data.
