Hand held GPS

Have recently bought garmin legend, took it out on the bike last Sunday,
only to find that the batteries only lasted 2 hours.
Can anyone recomend a stronger battery source.
Thanks Andy

If it will take rechargeables which it should try some nickle metal hydride (NiMH). I use some 2300Mah one in my digital camera and they last ages

Yes try the rechargeable ones that you use in digital cameras, they have twice the charging power of the usual ones. I cant remember exactely what their power is at the moment.

Also if the garmin has a light fuction on it, make sure its turned down or off all together, that will also save power, but at the end of the day these things do love to eat the power! but its cheaper with rechargable ones, keep a spare set charged so when the working set runs out, just replace with fully charged set. Of course the alternative is to hook it into the boats 12v power, thats far better! oh course you said a bike!
maybe its possible to run it off the power supply for your lights on the bike?
