Garmin echomap 74sv battery

Post by Bearwolf34 »

Am in the process of getting a Garmin echomap 74sv and cant find specs as to power usage of this unit.

Am thinking about picking up the 10ah nocqua pro power unit. I typically spend 10-12 hrs out in my kayak and am wondering if this battery provides enough "juice"?

Anyone used the new wilderness systems 15ah lithium battery pack?
