microSD card for Rino GPS?

[fishing4sanity]

I bought a Rino GPS for hunting this fall, skimming through the manual I never saw what size of microSD card to use. I found a good deal on a 4GB card, what size of card is needed?

Be careful on capacity and if your unit can handle SDHC(high capacity). Most SD cards over 2G are High capacity and will not work in standard SD. 2GB is a lot of Map capacity.
