Use on foot

[AlRaven]

I'm after one for about £150 or less but ideally I'd like to use on foot as well, what's the battery life like on the popular ones at about that price??

Yes, I think for my use it would really just come down to best battery life, on Garmin's website this seemed (250 or 300) to go as long as 8 hours???

P.S. Any comment on the Navman S series as the wife is probably renewing with Tesco and you get £100 off.
