USE THIS GPS RECEIVER ONLY AS AN AID TO NAVIGATION. A CAREFUL NAVIGATOR NEVER RELYS ON ONLY ONE METHOD TO OBTAIN POSITION INFORMATION. CAUTION This GPS receiver, (like all GPS navigation equipment) will show the shortest, most direct path to a waypoint. It provides navigation data to the waypoint regardless of obstructions. Therefore, the prudent navigatorwill not only take advantage of all available navigation tools when travellingto a waypoint, but will also visually check to make certain a clear, safe path to the waypoint is always available. NOTICE! As of this writing, the Department of Defense (DOD) has not declaredthe GPS navigation systemas operational. [. . . ] The MENU keyaccesses many of these features, allowing you to customize the unit to your particularneeds and water conditions. Although you may have to leave one menu and enter anotherto reach the desired function, the choices have been carefully worded to lead you in the right direction. All of the following features are accessed through the MENU key. PDF compression, OCR, web-optimization with CVISION's PdfCompressor 22 71 CHART FREQUENCY . 25 l:1:S1 nrn 0011 O. 0Oiiri . OUrin The Z-9500GPS operates from 50 or 192 kHz, either independently or simultaneously. The sonar unit comes with a 192 kHz transducer, other optional transducers are available. See the transducerdiagramon page 3 for single or dual transducerconnections. Thechart can operate from a differentfrequencythan thedigital sonar. r Chart Frequency I 36:3. 6 FT PLOTrER DIsPLAY Chart Speed I I I Turn -- Fish--ID On The plotter's radius shows at thetop left cornerofthe screen.

[. . . ] The 8 degree transducercovers only about a two foot circle. 10 Problems occur when the surface clutter extends to the bottom as shown on the right. The digital sonar cannot distinguish between surface clutter and the bottom and so it becomes "lost. " It may flash the last known bottom depth or it may lock onto an unrealisticdepth such as 900 feet in a lake that only gets 60 feet deep at its deepest point. If the unit is in automatic, the autoranging feature may change the range to an extremely deep depth, such as 0 to 600 feet. This compresses the information on the display, making it difficultto read. For 192 kHz users, the20 degree transducer is almost alwaysthe bestto use in fresh water, the 8 degree mostly in salt water. [. . . ]
