I am looking to upgrade my very old etrex (not the H version).
I have not kept up with the technology in recent years.
The short list is a etex30, GPSmap 62s, GPSmap 64
I am not bothered by all the Bluetooth connectivity stuff, the
electronic compass would be nice but not worth more than 10 or 20 bucks (I
have a perfectly good real compass and a map). the barometer is not of much interest to me either.
All have high sensitivity antenna, are they all equally sensitive?
(I assume the quad helix part is more to do with signal orientation rather than sensitivity)!!!
The 64 has glosnass (sounds good), does this improves positional accuracy at all!!!
or is the only real benefit, the faster lock on times and more
satellites to get a lock on?
Basically would I stand a better chance of finding a way-marked Stile a
km away with the 64 compared to the other two units?
I assume all three of the newer units will be less likely to lose
signal than my old etrex.
I am basically only going to use it in the UK.
Are there any draw backs to buying a package deal, one with maps on a card compared to buying them separate? There is a price advantage of course.
Are the bundled maps the same as the separate maps (same detail, accuracy etc.)?
I only use it when I going out on walks with my wife, we will not be attempting to follow 42 commando anywhere :-)
I would like, I think - open to advice, to have the 1:50k set of maps and selected 1:25k maps for the area we are holidaying in loaded into the device.
ideally the whole country at 1:25k would be perfect - but expensive.
I 'think' I read somewhere that if I buy the map on a card I can't transfer it to the device so I will be limited in what I can load onto the device.
but if I buy the map separate as a download can I load it onto a 16 Gig memory card along with other maps.
ideally i would like the full 1:50k of the UK (i see a package deal is available) and selected 1:25k for the area i am visiting all loaded simultaneously.
i don't really want to carry and change memory cards in the field.
how much memory does a 1:25k of a national park take up; how many maps can i get into the 16 GB card basically
Thanks for any advice/help
