HDS7 or HDS9?

The 9" draws minimal 2.0 amps and a max of 2.9 amps draw rate. Right now I am running a 7" live and pretty much had to upgrade my battery because a 15 amp battery was not cutting it. It would not even handle the HDS 7" carbon for a full day of fishing. I would imagine that you are willing to buy a LIPO battery correct? Unless you are gonna carry a 20 lb SLA battery? My 30 amp LIPO is coming in at under 9 lbs. The battery dimensions are reasonable also. I have it installed in a nylon bag mounted behind the center hatch. Batteries should always be secured somehow from flying around, needless to say. One other draw back with going to a 9" screen I could think of is the wind coefficient. The 9" would probably be like a sail. Being able to run a quad split screen with a 9" would be way easier on the eyes. But at what cost? If we were on a boat, I would say go for it. But take a serious thought about some of the real world drawbacks before pulling the trigger. Again, some of this might not be so significant if you are only fishing for short periods of time. But personally, I spend 8-10 hours, sometimes 12 or more hours on the water in search of that prize yellowtail. Hope this was helpful.

That's insane consumption, I was all day on a 17ah lithium for my 9" Garmin with juice to spare. When a FF consumes at that rate, brightness management is key(keep the screen on the dim side at all times).
