Frequency
Menu g Frequency: 200kHz, 83kHz, 50kHz, High CHIRP,
Med. CHIRP or Low CHIRP
The number of Frequency settings depends on what
transducer is installed, but the HDS Carbon and Elite Ti units
are capable of up to six settings. Reese uses High CHIRP and
feels like this is one of the most important things for video
game fishing.
“CHIRP allows you to get a faster response and the best
picture of what is below,” he says.
Sensitivity
Menu g Sensitivity g A+40 to A-40
Reese bumps the Sensitivity setting up slightly from the
default setting to A+2.
“I have experimented with all of the different settings and
now keep it at A+2 at all times. It seems to have the best over-
all picture,” he says.
Noise Rejection
Menu g Advanced Options g Noise rejection: Off, Low,
Medium or High
This setting can reduce interference on the screen and
give the user a better picture. Reese keeps his Noise rejec-
tion setting at Low.
“I don’t want to remove too much on my screen, so I don’t
miss any fish,” he adds.
Surface Clarity
Menu g Advanced Options g Surface clarity: Off, Low,
Medium, or High
Like Noise Rejection, Surface Clarity cleans up the screen
for a better picture and specifically reduces clutter near the
surface. Reese also sets this at Low to preserve visibility.
Scroll Speed
Menu g Advanced Options g Scroll speed: 1/9 speed to X8
speed
Scroll speed is the rate at which the sonar images move
across the screen. Reese runs it slightly faster than the
default at the X2 speed.
“I want to be able to get a better picture of the fish, and
the faster speed also allows you to see the fish for a little
longer [it creates longer arches and returns],” he says.
“Having it up too fast will hurt your chances to drop onto the
fish and still see the fish on your screen.”
Ping Speed
Menu g Advanced Options g Ping speed: Min to Max
Ping speed controls how fast the sonar signal is sent
down. It can be adjusted from Minimum to Maximum on a
scale of 1 to 20. Reese likes to keep it in the middle at set-
