Hey Rowdy,

I have the Garmin 172C and also the 178C on my Ranger. I ahve nto had them nor the boat very long but from what I can tell they are pretty awesome. Just received the data management kit from Garmin so I can load the card information on my computer. Have nto had timeto play with it, the data management kit, but it seems to be pretty cool. Not taking momma with you to the big store means the ability to buy what you want. SO SPEND nad have fun.

Later,
Marty
