Setting The Keel Offset; Setting The Water Temperature Offset - Garmin STRIKER Vivid 4 Owner's Manual

Setting the Keel Offset

You can enter a keel offset to compensate the water depth reading for the transducer installation location. This
allows you to view the depth of the water below the keel or the true depth of the water, depending on your
needs.
If you want to know the water depth below the keel or the lowest point of your boat and the transducer is
installed at the water line or anywhere above the end of the keel, measure the distance from the transducer
location to the keel of the boat.
If you want to know the true water depth and the transducer is installed below the water line, measure the
distance from the bottom of the transducer up to the water line.
NOTE: This option is only available when you have valid depth data.
1 Measure the distance:
• If the transducer is installed at the water line
distance from the transducer location to the keel of the boat. Enter this value as a positive number.
• If the transducer is installed at the bottom of the keel
water, measure the distance from the transducer to the water line. Enter this value in as a negative
number.
2 Select Settings > My Vessel > Keel Offset.
3 Select if the transducer is installed at the water line, or select
bottom of the keel.

Setting the Water Temperature Offset

You can set the temperature offset to compensate for the temperature reading from a temperature-capable
sensor.
1 Measure the water temperature using the temperature-capable transducer that is connected to the device.
2 Measure the water temperature using a different thermometer or temperature sensor that is known to be
accurate.
3 Subtract the water temperature measured in step 1 from the water temperature measured in step 2.
This is the temperature offset. Enter this value in step 5 as a positive number if the sensor connected to the
device measures the water temperature as being colder than it actually is. Enter this value in step 5 as a
negative number if the sensor connected to the device measures the water temperature as being warmer
than it actually is.
4 Select Settings > My Vessel > Temp. Offset.
5 Use the arrow keys to enter water temperature offset measured in step 3.
