Garmin 62 buttons wearing past the black in GPS technology and devices Posted July 2, 2011 Yes, it is quite possibly the dust (the first 8-day trip with the 62s was in the Namib desert...fairly cool with peaks of no more than 20-25 deg C, but very dry & dusty) that initially abraded the top clear coating on the buttons; not only my hands, but also my clothes against which the unit was swinging, were probably very dusty. With the work I do there is no way of keeping hands clean until after using the GPS - it gets used all the time through the day, in between bouts of digging up specimens, scrambling up mountains etc... As I said, I don't deny that my units get rough treatment - they are for work & are treated as workhorses! - but the point is that the 60CSx went on the same 8-day trip in the Namib (being used by my assistant), getting the same abrasive treatment AFTER an estimated 50 times this amount of similarly harsh (and often much harsher) treatment over close to 4 years, and yet there is no noticeable wear on the buttons to date. The term "rugged" is thus perfectly appropriate to use in advertising the 60CSx but NOT the 62s. I know a lot of people in the same line of work as me (environmental impact assesments) who use the 60CSx - many of them on my recommendation - who are definitely not going to buy a 62s after seeing what's happened to mine, and also many people in mining exploration etc, who likewise cannot afford to have a unit that can't take a bit of dirt & rough use. We simply don't have the time in the field to pamper our equipment! This WAS the reason for buying Garmin, but it seems that this has changed withy the 62s... I agree that there is a design issue with the 62s buttons being much less rounded, but there is also definitely a materials issue as well... I think the idea of collating info on serial numbers to see whether there is a defective batch issue involved is great - mine is 21F005598...it looks as though mine is a very early unit (I ordered it a month prior to product release)...if we can show a trend to Garmin, perhaps they will realise they need to recall a cerain set of these units.
