BAIT FISH The importance of baitfish to successful fishing can't be overemphasized. They are the principle food of all game fish In mostwaters.

Mostfishdon'tspawn unlessthewatertemperature iswithinrather narrow limits. To find the different temperatures, a surface temperature meter, such as the LDT-3000 is a valuableaid to your boat. This unit provides an extremely quick response to identifying the desired surface water spawning temperatures for various species. Troutcan't survive In streams that get too warm. Bass and otherfish eventually die out when stockedin lakes that remain toocoldduringthesummer.

Or thesolid, continuous markings made bythebottom. Typically, fishare identifiedby acharacteristic archthat separates them from their stationary surroundings.

The angle between the outside edges of thecone is the cone angle. --a Lowrance offers a choice of transducers with either an 8 or 20 cone degree angle.

J 121 t 0 PULSE PULSE Thereisa relationship between resolution and transmitter pulse length. Resolution,in thiscase, isthe ability ofa C sonar to separate targets. The shorter — the pulselength, the betterthe sonar's abilityto separatetargets. However, in deepwater,the shorterthepulselength, the less likely a return echo will be re- — ceived. In fact, the X-40 automatically increasesthe pulselengthas the range increases.
