Aaah .. with the backlight switched on we are using more power.
Not .5 amps any more, power draw is now 0.7 amps, and total power used is now 10 watts.
So now I know the maximum needs of my sonar power-wise.
And I can calculate time duration of the unit using a battery pack, just by reading the label, with my calculater.
So let's go:
GP1300s smallest pack: 2 hrs 36 mins, or 1 hr 51 mins with backlight.
GP2200s: 4 krs 24 mins, or 3 hrs 8 mins with backlight.
GP4300s 8hrs 36 mins, or 6 hrs 8 mins with backlight.
So once I know how long I plan to fish for, I can bring the smallest and lightest pack, but still have plenty power for the sonar.
And my storage pockets are released for other necessary fishing gear.
To be continued ....
