The GARMIN GPSMAP 168 Sounder's ENTER/MARK key lets you quickly capture your present position-- or cursor or map item position-- in order to create a new waypoint.

To accept the waypoint with the default name and symbol, press ENTER/MARK to confirm the highlighted `OK' prompt. To enter a different name, highlight the name field and press the ENTER/MARK key, then use the ARROW KEYPAD to enter the new letter/numbers and press ENTER/MARK when done.

Reference Creating Waypoints Creating Waypoints Graphically Waypoints may also be quickly created using the map display. This feature allows you to select any map position with the cursor and create a new waypoint. To mark a map item, select the desired map item with the cursor then press and release the ENTER/MARK key. If you select an item on the map, like a city, the GPSMAP 168 Sounder will use the text or name shown on the cartography as the default name. When selecting a map item, the option `Create Waypoint' will appear in addition to a description of that point and its distance and bearing from your current position. To create a new waypoint graphically: 1. If you want to create the new waypoint at an on-screen map item, highlight the map item on the map display. (NOTE: Pressing and holding the ENTER/MARK key will mark your current location instead of the cursor location, and bring up the `New Waypoint' page) If you are using a map item to create a waypoint, an information page(s) for the map item will appear first. Use the ARROW KEYPAD to highlight `Create Waypt' and press ENTER/MARK. To accept the waypoint with the default name and symbol, press ENTER/MARK. If you are creating a waypoint from an on-screen map item, the name and symbol will automatically reflect the selected map item's name and symbol.

It is important to remember that the fishfinder can not determine where in the coverage area the tree or fish are, only that the returns were received in the same time frame.
