531425-1_D - 727 Man_English.qxd 9/30/2005 How Sonar Works Sonar technology is based on sound waves. The 700 Series™ Fishing System uses sonar to locate and define structure, bottom contour and composition, as well as depth directly below the transducer. Your 700 Series™ Fishing System sends a sound wave signal and determines distance by measuring the time between the transmission of the sound wave and when the sound wave is reflected off of an object;...

Increasing the sensitivity shows more sonar returns from small baitfish and suspended debris in the water; however, the display may become too cluttered. When operating in very clear water or greater depths, increased sensitivity shows weaker returns that may be of interest.
Page 36 NOTE: The Side Beam Range requires the purchase of the WideSide® transducer. You can visit our website at www.humminbird.com to order this accessory online or contact our Customer Resource Center at 1-800-633-1468. To adjust the Side Beam Range: 1.

When speed input is available, the Big Digits View also shows the TripLog. See TripLog. Bottom Black: Bottom Black is a Humminbird® feature that "fills in" the area of the display below the bottom contour. Bottom Black is preferred by some anglers because of its high contrast and easy readability, even though it can obscure bottom hardness information.

Fish and other objects close to the bottom that fall within the dead zone will probably not be visible in the sonar beam. Precision sonar beams, such as the Humminbird® 20° beam, have a smaller dead zone than wider sonar beams.

Many Humminbird® units can operate across a very broad depth range (up to 2500 feet) which causes the unit to "look" up to that full depth under some circumstances.
Page 39
Many Humminbird® units operate at up to 40 times per second when in single frequency operation. Due to the limitation of the speed of sound in water, the update rate begins to slow as depth increases to deeper than 50 feet.

(i.e. two fish hanging very close, or a fish hanging very close to structure). Humminbird® findfinders provide a very good 2 1/2 inches of target separation in shallower than 100 feet of depth. Target separation decreases as depth increases due to the need for a longer Pulse Width to achieve greater depth.
The downlooking beam provides depth information directly below the boat. X-Press™ Menu: The X-Press™ Menu is a Humminbird® feature that makes the most commonly-used menu selections available with one press of the MENU key. Items that appear on the X-Press™...
