I’ll be traveling to Hamburg, Germany soon and I was hoping to purchase a handheld GPS unit to allow me to roam without having to worry about getting lost.

Obviously I would hope it’d be able to fit in my pocket. But I’d also need the unit to download a city map of Hamburg, be able to mark waypoint and have the ability to backtrack would be nice.

Suggestions from people that have used similar?

I am writing a paper on data availability on the internet. Based on all of the Golf GPS devices I have seen, I assumed that this information was freely downloadable somewhere. However, I have been unable to find it.

Is golf course GPS information freely downloadable from somewhere? If so, where? If not, do you think all of these companies are manually re-creating this information? Are they purchasing the data from a common provider? Who would that be?

It seems very bizarre. there are dozens (maybe hundreds) of Golf GPS doo-hickeys. Yet, the data alludes me. Thank you.

I really would like to understand the difference between Car GPS and Trecking GPS. Are they similar?

I mean here from the point of syncing with satellites. I saw some trecking GPS that sync with 12 ( 12 channels). Does that mean that they are more sensitive than Car GPS?

Is it possible to use car GPS for trecking

Or are there GPS that can be used for both applications at the same time, and may be also for sailing, let’s say

If they are identical hardware-wise, does that mean one can use maps files for cars on a trecking GPS, or vice-versa?

Thank you in advance.
