I INTRODUCTION
The Lowrance X-15 is a highly
sophisticated recording depth sounder. Thanksto a microcom-
puter, the X-15 can do more than any otherdepth sounder in its
price range. Full control of the sys-
tem is at your finger tips to meet
the changing demands of varying bottom conditions, waterdepth
and boat speed. You can select the unit's
sensitivity setting, suppression level, depth range, paper
speed, and the degree of gray line" usedto enhance the re-
corded information. The patented Lowrance variablesuppression systemnot only filtersout false signals withoutdistorting the real
ones, but is synchronized with the gray line function to provide clear signals underall conditions. The permanent record of whatyour sonar has "seen" is roiled and stored inside the case.
Small boat sonar systems are
routinely used to measure water
depth,examine bottom contours, and locatefish. Thecapability of
the X-15 goesfar beyond the ordinary. Clues to the composition
Figure 1
of the bottom are given — schools
of bait fish are easilydistinguished from solitarygame fish —
a continuous display of information about bottom contours and sub-
merged shipwrecks — fish closer together than six inches can be
shown separately— concentra- tionsof algae, mossor plankton
can be identified — attrolling speeds individual fish are com-
monly recorded with a characteris-
tic "arched" signature which dis- tinguishes them from their surroundings — layersof waterwith differenttemperatures can be de-
tected undergood conditions, and verticalmovement of fish, (up or
down), can be shown. HOW IT WORKS
When the unit is turned on, an
electronically regulated motor drives a
the right edge ofthe recording
paper. The marking stylus is attached to this belt. When the
stylus is atthe top of the papera small mark is made. This is called
the zero mark, and represents the surface of the water.

Thestyluscontinues to move down the edge of the paperwhile
the sound pulse is traveling through the water, and whenan
detected, the stylus makes another mark on the paper. The
depth of the objectwhich reflected the echocan be read infeet by
comparing its location on the paper to the depth scale printed
on the paper.
A variable speed motor drives
the papergraph. (The paper is treated so that the stylus will burn
it to leave apermanentblack mark.) During one revolution of
the stylusbelt, a very
will be made by the flexible stylus, but the paper will move a small amountbefore the next revolution.
Each markwill blend into the one
before, so that a composite pic- ture" ofthe targetwill be made,
one tiny mark at atime.
Due to the many features that
-this unit has, we have split the operation section of this manual into two sections. The first section,
-Section Ill, is entitled Basic Op-
eration" and covers everything that is absolutely necessary to use the
X-15 is a wide varietyof situa- tions. It will tell you how to use the basic controls — Sensitivity, Sup-
pressor, Paper Speed, Grayline, Range, plus a few special
functions.
This section will be adequate for most situations. However, once
the basic op-
eration of the X-15 as described in Section III, you may wishto try some of the features described in Section VI — Advanced Opera-
tion. This chapterwill explainfour other featuresthat will enable the
serious operatorto get the
maximum use out of this equipment.
We urgeyou to readthis man-
ual thoroughlyand familiarize yourself with the controls. Al-
thoughthis is a very advanced unit, it is easyto use, thanksto
the power of the microcomputer and the frontpanelcontrols.
Should you require extra help, our Customer Ser-
vice Department toll freeat
1-800-331-3889. (Oklahoma resi- dentscall collect- 1-918-437- 6881). A servicerepresentative will
be happy to help you.
II INSTALLATION
Mounting —
The depth sounder may be installed in any convenient area,
provided the unit can be tiltedfor the best viewing angle. Four holes in the bracket base allow wood
screw or bolt mounting. stiffenermay be required
