I have a garmin ff80, and it will run on a 9v battery. I cant say how long for, but I tried putting the backlight on and it still worked (if the battery were struggling, then the extra load would drop the battery voltage so much it would stop working). Or you can buy a small 12v rechargeable battery for about a tenner.
Nick.

Peter's link looks pretty clever but there is also a small torch like device available, My friend has one and I am seeing him tomorrow, so I will find out what it is.

Hi folks

You can run almost any sounder or a small 12 volt gel cell.

I have seen small plastic boxs made to hold the cell and the sounder display put on the top of it.

Even a small lead acide gel cell would run a sounder for a few hours but you can get then in various sizes depending on how long you want to run.

you can get them from Maplins http://www.maplin.co.uk or CPC on http://custom1.farnell.com/cpc/.

Search for lead acid on both.

Dont use normal lead acid batteries, they must be sealed gel cell to be safe.

Regards Gary

hummingbird portable

My portable Hummingbird (3 yrs old) runs a good week's worth of fishing on two 6-volt batteries. I believe the ad for it said 70 hrs. It reads to about 600' and seems to see fish well, too....better than I can catch them. Not terribly pricey, either. $150?? john

Welcome

Hi Seaskimmer, welcome to the forum where you'll get 100 different replies to the same question......but that's the fun of it !

So, here's No5

Do you have a centre console? If so, you have room to mount a sounder and space beneath to place a battery. What you can't do (as far as I know) is keep the battery charged via the engine!

Taking this aside, if you install a battery you're then able to run the sounder plus any other instrumentation (vhf - nav lights - 12v socket) etc, which, must be an advantage. Further, you'll find these battery operated and hand held units just as costly, if not more expensive than a straight forward 12v version.

Keep us informed...........

Further to the wise words of Mr MeMe there is a chance you could purchase a conversion jobbie (just a diode pack on some engines) for your engine to output 12v DC. If you let me know the exact age and model (or serial no) i'll find out for you.

I did exactly that on a Yam 30 recently - added a diode pack to a pull start engine and used it to charge a battery. Cost about 45.

depth sounder

well gang thanks for the replies, there is a wealth of info in them with some really usefull links, but after carefull consideration i might go down the line of installing a re-chargable 12v battery in my centre console.i have seen a device thet has two battery clips and a cigarette lighter similar to one.s in cars. i wouild then be able to use a fixed vhf+ echo sounder,i wonder if you could use this eqpt straight from the batt, if so how do you go about it, it,s not a problem for me to re-charge my batt after use as i have a charger, and would only use it for 6 hrs max..


thanks
