The 62S is part of the 62 series of GPS receivers from Garmin. It was meant to replace the 60CSX series. The functions are largely the same as the 60CSX, for details of this click here:
Garmin GPSMAP 60CSx HandheldRather than repeat the information, I'll just say the differences between the two.
PRICE
=====
First, the price. The 60CSX being "obsolete" now, is half the price of the 62S in the shops. Online it's a little cheaper. However I actually believe, given my experiences of both units, that the 62S should be CHEAPER!
BUILD QUALITY
=============
The build quality between the 2 units is also noticeably different. The 60CSX is made from a hard wearing, rubbery plastic, that can take a lot of knocks without much sign of wear, and feels solid and reliable in the hand. The 62S on the other hand is made from a lighter plastic material, which makes the unit feel like a cheap plastic toy in the hand. It also is plagued by problems such as a "squeak" when the side of the unit is squeezed or buttons are pressed. Finally, the material the screen is made from is also highly prone to scratching. Whereas my 60CSX survived years of abuse, getting dragged through all kinds of terrain without any significant scratches on the screen, my 62S survived less than a week before it had a large scratch running down the screen, making it hard to read the text. If you opt for this unit, get a screen protector!
DEVICE SOFTWARE
===============
And finally, how the unit handles. I honestly found the technical aspects of the 62S pretty similar to the 60CSX. Accuracy wise they are pretty much the same. If anything I found the 62S took a little longer to get a signal lock than the 60CSX. A pleasant upgrade is the text entry menu is easier to use on the 62 than the 60 series, with a better onscreen keyboard layout.
The 62S felt a little less responsive when I was using it, compared to the 60CSX. This I think is to do with the more flashy menus, with animated menu transitions etc. As I use these devices in my work, I just want a unit that does its job well, and quickly, and as such much prefer the 60CSX when it comes to the menus.
The 62S supports nicer colour maps, including satellite imagery. One thing to note regarding the satellite imagery is to preview/check the coverage of the areas you want before you fork over your money. I learnt the hard way a few years ago, and bought the "Birds eye satellite imagery" upgrade for a trip to the lake district. When I went to download the imagery, I found the entire lake district covered in cloud, making the maps pointless. I tried to get a refund, but Garmins customer support didn't want to know. In my humble opinion it was extremely poor to sell satellite imagery with such cloud cover, especially when it blankets the UK's most popular national park & walking destination!
AFTER SALES SUPPORT (GARMIN)
============================
My final note is regarding Garmins customer service. They don't really care that much about owners of their products. If, like me, you want to repair your scratched screen, they won't just replace the screen, they'll replace the whole unit, and charge you a premium for it. My troubles didn't end there, as the replacement unit they did send (yes, I was a fool and paid the premium!) was faulty, and will actually lose power if it is knocked (pretty shoddy I know!) for ages I thought I didn't know what was happening as I'd be out walking and then discover the unit had turned off, thinking it was dodgy batteries at first!
After finding out what was happening I contacted Garmin, who wouldn't do anything without proof of purchase. This was highly annoying, as the unit was a replacement SENT by Garmin (so no proof of purchase for it) AND it was actually listed on my Garmin account page as being in warranty still, so all the details were actually on their system, but they wouldn't help anyway, despite supplying a faulty product.
CONCLUSION
==========
My concluding remarks are that in all honesty the 60CSX is still better than it's successor, and cheaper too. The 62 series is still getting its kinks ironed out, and my experience with Garmins customer support has been such that I will no longer consider their products, both for personal or work use, as I require actual customer SUPPORT. I do hope you find this useful!
UPDATE!!! 29/04/2012
====================
I've now finally had Garmin concede the issue with my unit, and they have replaced it with a refurbished model. The previously mentioned issues regarding build quality appear to have been resolved, with the casing feeling slightly more robust and no squeak present. The unit certainly feels less like a plastic toy. Does this mean I prefer the unit to the 60 series? I'm afraid not. I still feel that the 62 series attempts to do too much for its hardware, with the user interface seeming a little bloated and slightly slow to respond (compared to the 60 series interface). I'd only consider the 62S if you can't get a 60CSX for cheap, or find the 62S for less money!
