INTRODUCTION

The LMS-150 represents one of the best values in sportlishingsonar today. It rivals, other sonar units costing much more in features and

perfo'mance. Withits menus, the [MS-iso offers easy-to-use opera- tion at the touchof a buffon. The CLEARVISIONTMscreen showsthe underwater world with high resolution and detail. The'[MS50-i also

displaysboat speed, surface watertemperature,anddistancetravelled

(distance. log). The loran module gives you a full featured loran re- ceiver,complete with plotterand waypoint navigation capabilities.

Although the [MS-i50 has many features and functions,the 'softkey" menu system makes it easy to use. Above all, don'tbe afraid to try

different featuresand functions on the unit. You can'thurt ft by press- ing buffons!

MOUNTING

You can install the LMS-150 in any convenient location, providedthere is clearance behind the unit. Place it in positionfirst and tilt it br Ihe

best viewiitigangle. Thenmarkthe holes in thebracketbase. You can

use woàthscrewsor through-boltsto attach the bracket to the boat. You may heed to place a piece of plywood on the back of thin fiber-

glass panels to secure the mounting, hardware. Make certainthere is enough roombehind theunittoattachthe powerandtransducercables.

The smallest hole that will pass one poweror transducerplug is one inch. Afterdrilling the hole, passthe transducerconnectorup through the hole first, then pass the powercabledown throughit.

After royting the cables, fill the hole with a good marine sealingcam- pound. Offsetthe bracket to coverthe hole.

The[MS-i50has reversepolarityprotection. Nodamagewill dccurtothe unit ifthepowerwires are hooked upbackwards. However, itwon'twork

untilthewiring is connectedproperly.

Minimize electrical noise by routingthe power cable away from other possible sources of electrical interference. One of the largest noise

generators is the engine'swiring harness. For.best results, keep the powerand transducercables awayfromthe engine wiring.

Attachthe speed/temp sensor'sand loran module'scableto the [MS-

INSTALLATION- LC-1 Loran-C MODULE

When choosing a mountinglocation, remember to install the E[C-1 where it'sclearofother antennas, wires, masts, or otherobstructions.

A high location is preferred, however forlightning protection, the an- tenna shouldn'tbe the highestpart ofthe boat. Theantennashouldbe

mounted vertically. Makecertain itis as farawayas possiblefromVHF radio antennas.

Improper. performance can also occur if the antenna is mounted too close to metal objects such as tuna towers. Again, a location that places the Loranassembly in the clear is preferableto one that is high and obstructed.

You must purchase an eight foot stainless steel or fiberglass whip antenna:. The threads are standard 3/8-24 for the whip. A ratchet mount base is most commonly used to mount the Loran to the boat.

The base mounting threads are conventional 1"-14 machine thread

(NOTpipe thread). This allows the use of standardantennamounting hardware. Tighten all hardware securely.

The cable supplied with the LC-1 is thirty feet long. Do not cut the cable if its too long. Instead, coil and store h

extension cableis available ifthe cableis too short. Ask your dealeror call your local servicecenter or the Eagle

departmentfor moreinformation.

TheLC-1 can be attached to aswivel bracket or hollowextensionmast, if desired.

SPEED/TEMPERATURE SENSOR INSTALLATION

Mount the speed/temp sensor on the boat'stransom in a locatien where the flow of water is smoothest. There should be a minimum

amountofturbulenceand air bubbles in the chosen location. The port

(left)sideofthetransomis preferred,.however thestarboard(right)side can be used if necessary. Do not mount the speed sensorbehind strakes, ribs, or thru-hullfittings that will disturb the flow ofwatertothe

speedsensor. In atypicalinstallation, the speed sensorismountedsix to twelveinches frpmthecenterline ofthe boat. The sensormustbe in

the water at all times to function properly. Make certainthe chosen locationis in thewaterevenathigh speed or whentheboat isonplane.

Oncetheproper location has bean determined, placethe sensoronthe transomwiththebottomofthe sensor flushwiththe bottomofthe hull.

Mark the transom in the centerof each slot and drill a 5/32" mounting hole. Mountthe sensortothe hull with #10 stainlesssteelscrews (not

included). Use a good grade ofcaulking compound to seal the screws.

Adjustthe sensorso it isflush with the underside ofthe hull and tighten the screws.

It the base of the transom has fill the gap between the

transom and the sensorwith caulking compound to insure a smooth water flow.

Route the sensor cable to the in-line connector on the sonar unit's powercableand attach it.

FREQUENCY SELECT

Lowrance offers both 50 and 192 kHz transducers for the [MS-I50.

The 192 kHzfrequencytypicallyhas superior targetresolution,showing fish, structure, and bottom definition betterthan 50 kHz. However,the

192 kHz doesn't	water	as well as 50 kHz, thereforeit won't
penetrate

go as deep. Also, 192kHz cone anglesare typicallynarrowerthan the 50s. You can drawa fewconclusions fromthesestatements.

1. Use 192 kHz (especially in shallowwater) with a wide (20 degree) coneangleforthe best resolution andtargetdefinition. Use a 192 kHz narrowconeangletransducer(8 degree)whenoperating in mediumto

deep depths.

2. Use the 50 kHz in deep wateror where a very wide cone angle is desired: Using50kHzwhenfishing withdownriggersgenerallylets you

see the downriggerweights display on the screen. Lowrance offers both a30degreeand 45degree cone angles for 50 kHz.

The LMS-150 has the capability to oper-

ate at 192 kHz or 50 kHz. It can display echoes from either transduceror both at

the same time in an unique split-screen mode. Once the transducers are con-

nected to the [MS-i50 (see the Trans- ducerConnectionssectionfor more infor-

GRAVLINP

GRAYLINBTh lets you distinguish between strongand weak echoes. It

"paints" gray on targets that are strongerthan a preset value.	This
allows you to tell the difference betweena hard and soft bottom.	For

example, a soft, muddyor weedy bottomreturnsaweakersignal whibh displays with a narrowor no gray line. A hardbottom returns a strong signal which causesa wide gray line.

If you have two signals of equal size, one with gray and the other

without,the target with gray is the stronger signal. This helps distin- guish weeds fromtrees on the bottom,or fish from structure.

GRAYLINE® is adjustable. Since GRAYLINE® shows the difference

between strong and weak signals, adjustingthe sensitivity may require a different GRAYLINE® level, also. The level chosen by the LMS-15O

at poweron is usually adequate for mostconditions. Experiment with your unit to find the GRAYLINE you.
