Garmin Montana 650T
on 13 October 2012
Bought this for mostly for walking, it's still early days but so far I cannot fault it.
It is very well built and bigger than it looks in the pictures, overall 5 3/4" x 3" x 1 1/2", it has a 4" screen, that is overall 3 1/2" x 2", much bigger than the Satmap gps screen, it is the biggest pocket sized gps I could find, which is exactly what I wanted, I find with most gps the screen resolution and detail of maps is great, but to navigate easily you need to see what is around you to get some perspective, by the time you have zoomed out on a smaller screen it all becomes hard to see, the bigger Montana screen really comes into its own here.
I am really pleased with the sensitivity of the receiver! I can switch it on anywhere, indoors or out, and it knows where it is in seconds, compared to my Satmap unit which often takes 3-4 minutes to decide where it is and has to be outside or at least by the window, or worse still my (much) older Garmin unit which has to be waved around in the air outside!
I went for a walk with the Garmin switched on, but left in my coat pocket, I got it out and checked it every 10 minutes or so and was amazed to find it had not lost itself at all, considerably better performance than the Satmap unit it has replaced.
The Montana comes with a respectable and quite useful base map, but as always its the detailed maps where they get you, mine will potentially get used all over the UK, the entire country 1:50000 OS map micro SD card cost me an extra £200-00p.
It can show 3D maps and the screen automatically switches between landscape and portrait depending on how you are holding it, I have bought a suction pad holder to use it as an in car sat nav if I need to.
Not to sure about battery life yet, but the rechargeable that comes with it seems quite promising, after an hour and a halfs walk it still had 85% charge, so thats potentially up to around 9 hrs, if the rechargeable runs out then its easy to put 3 x AA batterys in and carry on.
To sum up, its expensive, but worth every penny, possibly the only gps you will ever need and my favorite new gadget!!
