Humminbird id-1 User Manual

 
Humminbird’s exclusive Total Screen Update instantly updates the entire TCR screen to 
include new information each time a function is changed no waiting for the changes to 
“march” onto the screen. This feature is valuable in 2 ways: 
 
1.  Changing depth ranges. When the depth range changes to a deeper or shallower 
scale, the entire screen changes to display the new depth scale. For example, if you’re 
in the 0-60’ scale and it changes to the 0-30’ scale, the entire screen will look as if you 
had been in the 0-30’ range all along. 
 
2.  Using zoom and bottom-lock. Through Pixel Memory Capacity, the memory in the 
TCR ID-1 stores readings in much finer detail than is displayed in the “regular” mode. 
So when you activate the zoom or bottom-lock functions, the entire screen changes to 
display the up-close detail that is stored in memory. Then when you turn on the zoom or 
bottom-lock, the whole screen will change back to the full depth scale.
