Now the unit will create a GPX file on your memory card each day containing all the saved data including elevation and time for your activities. Those files can then ba accessed via the USB mass storage mode or via an external card reader.

Your memory card is also used for maps and custom POIs. As it's a FAT-based filesystem, there is also some per-file overhead and rounding to nearest blocks and such.

There's some overhead in the GPX file and there's some overhead per track and per track segment. As the data is stored as readable text, each individual trackpoint may even vary in size - for example elevations in the mountains have more digits and thus consume more space than elevations near sea level. Longitudes neare the prime meridian have fewer digits than those near the date line.

Now, with that weaseling out of the way, we can still glean some numbers. In a survey of The number of bytes in each file total 19,,, so we get approximately bytes per trackpoint.

That comes to almost 9, trackpoints per megabyte. So if you have the unit set to record trackpoints at the maximum rate of 1 per second and are logging around the clock, budget about 10MB of track data per day. New files will be created at midnight GMT. It may be because the limit for a map file itself is 4GB, but having 8GB lets you do map-filename-switching tricks. Another difference between the two is that you can change microSD cards in a 76CSx without removing the batteries, while you have to remove the batteries first with a 60CSx.

I am appreciating the information. I am not sure which of the map programs or both I should be considering as it was just posted by "Coggins" I could download free maps. So, I am now trying to figure out actually how much moola I will need to spend. I am primarily interested in having the maps for around the Adirondacks. And, I wonder if I went with the USA collection would I be wanting the 24K maps later or would it be best to find free maps online as suggested by Coggins?

How equal would you say the maps are? Do a search and you will find many long threads discussing difference between 76 and 60 series GPS. I beg your pardon but I but I don't really understand why you would advise the thread should be closed. The point of the thread is to try to find an understanding of which GPS might fit my situation.

And, technology, prices, and opinions change. I have in fact searched through the forum and still felt the need to ask relative to my specific situation.

Please, kindly ignore the thread if it bothers you. Many thanks to those whom have responded and as of now I considering the two Oregon models. I am sorry if I am missing something here. Someones grumpy! If it's redundant ignore it, it'll fall quick. I will say this, the "Search" function on Groundspeak Forums is kind of screwey. I search, for example, PN and get a billion threads with the word PN somewhere in the thread.

It's not helpful at all really. They should refine the search engine to focus on thread topics instead of content and you will get alot fewer redundant threads because people won't give up on scanning volumes upon volumes of hits when they search. SD vs. The SD is convenient since you don't have to do anything. The disadvantage is that you can not use the map on your computer, it is only good on the unit.

Verified purchase: Yes Condition: Pre-owned. The unit is very accurate, often to within 10 feet. The antenna which gives you extra gain is not needed separate purchase as the unit is very accurate without it.

The plug in for 12 volt power supply is very handy to spare the AA batteries, but must be purchased separately. For being most useful, you must purchase maps, such as Bluechart for marine use , topo for hiking , and city navigator to have all the streets in the USA.

Ebay is the best place to buy those. The map which comes with the unit is fairly accurate, but low on details. It gives major intersections, general outlines of lakes, etc. I love the built in electronic compass and altimeter.

I love that it is watertight and floats. The sun-moon feature is great. The screen is a little hard to read in the shade, but gr eat in the sunlight. This partly depends on what color background you choose. The backlight works great, but lowers battery life if you don't have it hooked to external power. The unit, along with the bluechart software may have saved my life.

Coming into Bodega Bay from the ocean in my boat, in dense fog, I was able to skirt around some dangerous rocks and steer directly into the harbor. I couldn't see 50 feet! I bought it after comparing features with many others. I haven't been disappointed. I wish all the maps were included, but they really are the products of hundreds of maps seamlessly put together, so in reality they are a good buy also.

The micro sd card is nice, but unless you are going on very very long trips, the 76cs or 60cs will hold lots of data. If I had to do it over, I would probably get one of those, as the built-in memory holds enough data for several states.

All in all, I have had fun with this unit and expect to do so for a long time. Mack Read full review. As this is my first GPS unit, I have little to compare it to. Being impatient with slow technology the 'x' feature which allows faster satelite acquisition was important to me.

This appears to work well. I've found the screen to be good in almost all lighting situations, and the menu system is adequate - I can find most functions, even as a new operator, within a few passes through the menu list. Alas, mapping seems to be the biggest concern amongst other users, and I have found it to be lacking as well. The basic road mapping is just that - basic.

But that is usually sufficient for cross country driving. I wonder, though, how accurate the internal mapping is. I have been on several roads where it appeared we were ft or more off the road, and my boat's "position" while on a lake seemed to be on dry land.
