You don't need to be an 'investor' to invest in Singletrack: 6 days left: 95% of target - Find out more
I'm looking to start covering some bigger distances on my new build and rather than stumping up for a Satmap etc I'm hoping to use my iphone6. I did attempt this with previous iPhones but they usually ran outta puff due to the demands of the constant uplink on GPS via mapping aps etc. The iPhone's 6 battery is better but I still need a mountable case and would like a extra battery pack in a single compact unit.
Does anyone have/use a particularly good type that they would recommend? It does without saying it needs to be all weather.
Cheers.
Update on this smokin hot thread...
Rokform sport looks like the one! Although I will still need a ancillary battery pack.
Use one of the solarstorm battery boxes it has usb out.
Top tube mount it like you would for lights
