tiki-stick

I own a Renegade 18 1999 w/150 love it/ 63.8 gps 26" Raker prop does me good and gets me to the fish.

Etrex Vista also great little unit and full of memory. 24mb, i use mine for salt water and fresh. plus you get real time speed for the speed freek in all of us. good luck with your purchase. oh one more thing--the unit comes with its own software but you can buy the garmin lake map cds for the down loads of a specific lake.
