CONE ANGLE INFO
A feature unique to the MX-7GPS is the “Sonar Footprint” that
displays the actual area being covered by your transducer while you
are fishing. This data is displayed below the cone angle icon and
represents the diameter of the base of the transducer cone.
This will keep you constantly updated how much area is being
covered by your MX-7GPS and will help you decide which
transducer angle best suits the conditions. When the MX-7GPS is
first turned on, it will be transmitting utilizing the 20-degree setting.
When switching between cone angles and depths, the Sonar
Footprint will change accordingly.
Conditions where the narrow beam will benefit you are:
— Fishing in deep water (over 40’)
— Fishing along very steep drop-offs for bottom-hugging walleyes
— Fishing in big schools of fish, like suspended crappies
— Fishing in and around heavy weeds or standing timber
— When fishing in a crowd, the narrow beam will help reduce
interference.
ZOOM INFO
One of the best features to have in an ice fishing Sonar is a “Zoom”,
and there is none better than that of the MarCum MX-7GPS. A
Zoom feature enables you to have a magnified view of a selected
portion of the water column. Note that when the ZOOM window is
open, you can still view the entire water column on one of the other
windows. Imagine that you are fishing for walleyes in 30 feet of
water, and you are zoomed in on the bottom 5 feet. If a school of
crappies comes through at 20 feet, you will be able to easily see
them on one of the other windows, and quickly raise your bait to
their level. The position of the ZOOM window is adjustable in one-
foot increments and can be moved to focus on the bottom (for
detecting bottom-hugging fish), or at any level above bottom for
suspended fish.
