Diel11,the slow bootup isn't a problem for me anymore.as you no I have my transducer mounted on the trolling motor so while moving from one location to another was a concern for me(turning the unit off then waiting for it to boot back up when I turned it back on)On the 998 I would just push the power key,then turn sonar off then turn it back on when I reaches a new location.i just learned that on the onix,I. can touch the top right corner of the screen.a drop down menu with standby option is shown.when I push standby the onix immediately shuts off.when I touch the power key,it immediately turns back on.i believe now that I no this,I turn the unit on one time and just use standby until I ive done for the day.(wife just informed me,times up.off to do more hunny dos.)
