Tired from ohararp after it took them two weeks to answer my first email about two weeks they haven't answer the second and third email, or on the message I left them on the machine, or my references to Skype.

So I'm trying to find a gps data logger from another company, and for lack of time, I prefer him to be available. So far I found some models with a solar panel on them, a very important feature for me, but I couldn't find any model with an option to expand the memory. The models come with the ability to store coordinates 50-60,000, which will do a little less than 3.5 days. My rough calculation, a 2 GB card can suffice to 400 + days (with samples every 5 seconds), then it would certainly be a lot more comfortable for me.

Does anyone here understand and know the specific model? Or specific store that can help me?

Thank you very much.

Why sample every 5 seconds? How have you been moving at five seconds?
Tdegum 10, 30 minute. (50 m)

About solar panel-I see no reason to cry about. Buy Panel and fit it to your device. (Search for DIY sites)


I don't know but I'd like models and if you share us so I can buy in the future.
ד"א what the magnitude of the price?

Oh, look what I found: DIY
Did It yourself.

Now I'm left to obtain components (where I find GPS unit!)

That's exactly the point. I don't have the energy to do it myself.
Of these oharap was supposed to come with solar panel cutter (maybe without the Panel itself, but to connect connection Panel I can do by myself) and all the features I want.
To build such a job alone must check, Waco regional, renovate, dabag. I want a product ready to do.
And 5 seconds the arbitrary decision. But if I find that with SD, I just buy a blank card by its price, and then calculate how often I need to sample for it enough. In the showdown, if I go 10 hours per day, so that every five seconds, then samples 7200 I need someplace to about Max samples 324000. 128 MB card will suffice for that amount. I don't think you can find a card that size on the market today. In conclusion-there is no card slot problem.

I just think that a sample should be 30-50 m (considering the speed, of course) that is about 30-50 seconds. (Average speed 4 km/h = pulse 1.11) and reach 1200 in 10 hours. (What about turning off the device breaks?)

The file you made about SJ's 2000 points and weighs about one megabyte, just not something (accuracy of 500 m) and increasing the number of points according to 5 receive a high-resolution file and really heavy.

On the other hand you can always dilute points after recording.

Actually, sample's top spot by distance rather than time is definitely makes more sense anyway. Just the ohararp don't suggest it, so I didn't think of that.

If I adgum every 50 m, say 1000 in the Israel National Trail (INT) is, that means I have 20000 total points I missing something here? If so, then maybe the simplest models I saw in the country with solar charge enough for me (allow 50-60 thousand samples).

On Sunday I'm going to call one of these stores to find out the details.

Anyway, I finally adlel the whole excess dot points the same as previous point (only in case of sample per time), or on the line between before and after, to some small variance. But it is only in the House after the path.
