Best GPS for guerilla growing?

Been looking and debating this model:

Color screen great for terrain differences and maps of many many many water sources with good trail mapping, plus the maps are update able and uses an sd card so can encrypt the sd. Seen better but I am on a budget here...

What gps do you use? what do you look for in a grow gps?

why would you need a gps you don't have a good sense of direction? just use your mind its safer you get caught out there with a gps there going to find every plant you have. if you have a really bad sense of direction get a map and a compass but don't mark your grow spots on the map just remember where they are.

Police can use the GPS in your cell phone to track you, I'm pretty sure they can also track you from that GPS unit in either case they don't even need a warrant.

So the best GPS for outdoor growing would be : a good old map & compass + the knowledge to use them

my gps is between my ears

Looks like smart money would not go towards a GPS. Now you have more money for seeds and grow gear. lol

I have used a map before, it got me robbed. Long story... many lesson's learned from it. I marked the patches my car got robbed thought nothing of it when I couldn't find the map but the friggin' tweaker's musta got curious and followed the map. Hence why I planned to encrypt the SD card.

I have a decent sense of direction but memory issues and HORRIBLE eyesight (I can't see more than 10 ft in front of me past dusk much better in daylight though.) I thought a gps would be helpful as I want to do small small small patches but very far from each other in relatively remote locations. Last time I did that lost 2/3rd of my crop to changes in nature putting me in a position where I can't remember how the heck I got to my tiny patch. I dunno I guess I will have to rely on my partner even more to help me remember where everything was put. Not the news I was hoping for but alas se la vie.

Thank you very much folks, advice appreciated.
