Introduction

Thank you for choosing our fish founder—FS117

The FS117 is a high quality, dual-frequency fish finder. It uses TFT LCD to

provide a color display for easy daylight viewing that can be dimmed for

night fishing. With 8 or 12 colors bar, the colors represent different signal

strengths, making the displays easy to recognize the bottom and fish

schools. You can choose table mounting or flush mounting for optimum

viewing.

FS117 is consist of the following two parts:

¾Operating & display unit

¾Transducer

Theory of fish finder

The fish finder converts each echo into an electronic signal, displayed as a

vertical line of pixels. The most recent echo appears on the extreme right of

the display, with the older echoes being scrolled towards the left, eventually

disappearing off the display.

The transducer generates an ultrasonic

pulse, which travels down towards the

bottom at a speed of about 1500m/sec,

spreading out into a cone shape. When the

pulse meets an object, such as a fish or

the bottom, it is partly reflected back up

towards the boat as an echo. The depth of

the object or bottom is calculated by the

fish finder by measuring the time taken

between sending a pulse and receiving the

echo. When an echo has been returned,

the next

ulse is sent.

GAIN

【GAIN】+&【GAIN-】

In single frequency model, press 【GAIN+】or 【GAIN-】to adjust the gain

value for the clearest echo.

In dual frequency model, press 【GAIN+】or 【GAIN-】to adjust the gain

value of dual frequencies simultaneously.

Operation

PIC

Set the picture feed rate (to the left): 0, 1/4, 1/2, 1/1, 2/1, 4/1.

AUTO_RANGE

“AUTO_RANGE” means Auto-range; the basic range will change

automatically to always show the full depth from transducer face to bottom

regardless of changes in depth.

When “A_RANGE” function is on, the screen will indicate “AT” on the upper

right. Then operator can’t change the range manually.

TVG

TVG is to suppress unnecessary echoes near the water surface such as

bubbles and floating matter.

Each press of the 【】or【】key changes the ability for suppress the

echoes as follow:

Operation

NOISE REJECTION

NOISE REJECTION is to reject noise interference from nearby fishing vessels.

Each press of the 【】or【】key changes the ability for rejecting the

interference as follow:

The fish alarm is available when the fish school is deeper than 2m deep.

SIGNAL DELETE

Colors indicate the strength of the echo from strong to weak.

The weaker colors can be deleted to show the needed echoes clearly.

Cancel 0~5 colors (when 8 colors chose).

Cancel 0~7 colors (when 12 colors chose).
