• **Battery Life - 15hours. I plan on lots of rides which could take upwards of that time. This makes the Garmin a poor choice unless I can find an backup battery pack which runs on AAs (The same as my lights). This becomes essential during things like touring and other multiple day rides.

    *yeah - i'll be testing one of these in the next few days.

    **Cost - It's a lot of money but my current concept is thus, Maps of all of the places that I wish to ride would add up to a similar if not more excessive cost. The Garmin is just outlaying all of the cash at one.

    *I think I ride enough to make good use - if i don't get good use - i'll flog it

    Lack of GPS Signal - Without using one I've no way of knowing how often it will lose signal. For certain rides this could mean taking paper based maps too.

    I think as long as you can see the sky

    I've basically worked out that the best solution to my situation is a mixture of the following, paperbased maps (pages ripped out of a road map) or handwritten route notes for rides that I have already done. This will jog my memory on the bits that I forget or fail to recognise.**

    *I'll be taking some paper maps and compass, and iPhone as backup... But plan to geek on the data after- so hoping to keep the GPS on all the time.

    Sure.
