Thermoclines are shown as the weakest colors. One of the unique features offered by Garmin is See-Thru technology, which allows the GPSMAP 495 to hear both weak and strong signals simultaneously so as to identify fish returns under the toughest conditions, such as suspended in thermoclines or even hiding near structures.
Viewing the Sonar Temperature Tab NOTE: You must be receiving proper sonar data from another device, such as a Garmin GSD 20 or GSD 21 Sounder Module, to view temperature information. The Temperature sub tab provides a visual graph of water temperature changes over a period of time.
TIS Traffic is available to aircraft equipped with a Mode S Data Link such as the Garmin GTX 330 Transponder. TIS Traffic from a GTX 330 Transponder can then be shown on the GPSMAP 495. Surveillance data includes all transponder-equipped aircraft within the coverage volume.
Other limitations and anomalies associated with TIS are described in the AIM, Section 1-3-5. Refer to information. NOTE: Garmin is not responsible for Mode S geographical coverage. Operation of the ground stations is the responsibility of the FAA. Refer to the Aeronautical Information Manual for a Terminal Mode S Radar Site Map covering the U.S.

Occasionally, aircraft maneuvering causes this algorithm to induce errors in the GPSMAP 495 screen. These errors primarily affect relative bearing information and traffic target track vector (it will lag); intruder distance and altitude remains relatively accurate and may be used to assist in “see and avoid.”...
The GPSMAP 495 supports TIS input from a Garmin Mode S transponder, such as the GTX 330. To configure TIS input: 1. Press MENU twice. The Main Menu appears. 2. Highlight the Setup tab. 3. Use the ROCKER to select the Interface sub tab.
NOTE: TIS audio alerts can be turned off in the Main Menu Sound tab. Traffic Ground Track Traffic ground track is indicated on the GPSMAP 495 screen by a “target track vector”, a short line shown in 45-degree increments, extending in the direction of target movement.
3. Highlight Set Up Map, and press ENTER. 4. Highlight the Map sub tab. 5. Select TIS Traffic, and use the ROCKER to change the Zoom range. GPSMAP 495 Owner’s Manual Highlighting TIS Traffic Using Map Page Panning Another Map Page feature is panning. Refer to information.
