Power For A Hummingbird 150

[rb56]

which is what i bought for my canoe and have had it plugged into my trolling motor battery. i'm installing a dash on the canoe and i emailed hummingbird asking what all would the finder run on, they said 8 AA batteries, 2 6 volt lantern batteries, lawnmower...anything i can get 12v from. i got two of the 6v and a dash mount cigarette plug that was in my pickup. i connect the batteries and the light on the unit comes on. i haven't got as far as plugging the finder in yet. has anyone ever used 2 6v and how long will they last? i saw somewhere online they last about 3 full days of fishing. i'm trying to avoid the cost and save space and weight of another battery. anyone?

[Hi Salenity]

I use 8 AA's and they well last for several trips out if I remember to turn it off.

This is what I use for my kayak's fish finder. It works great and is pretty small and compact.

It can be done. I used to run a portable like that 30 years ago. Make sure you fuse the + to prevent damage to the finder. 3 amp inline glass or automotive type. The fuses and fuse holders can be found at any auto parts store. Eventualy a rechargable is the way you'll want to go.

i have a fuse, i've been using it off my trolling motor battery which has a box i made with external posts and in the end a cig lighter plug which is where i have been plugging it in. i've been going at times when it was still dark and used the plug for a flood light. i bought two 6v lantern batteries and have a port that was in my truck. i'm wanting to mount the port and fish finder on a dash i built for my canoe. i got it to come on once and my hand held cb was plugged in and worked. i wondered about the 8 AA, how do they connect?

MIne is a HB 570 ci DI, which has gps and down imaging soI will asume that it would use more power than a 150 and I can use mine all day off my 8 amp hr battery
