The 1197 adds a whole new meaning to 3g.. Or do I mean 3k!! It was tuff to decide wether I wanted to sleep or go to the lake and mark a few waypoints last night.. Who needs sleep when you got a 1197c si!! If its okay with you I may be asking some questions later.. The 1197 makes my Tracker PT175 look like a jon boat.. I'm going to have to shift the batteries around in the boat to keep the boat from leaning to the port side.. That Hummingbird is a hoss!!! Puts off some serious heat too! Your gonna laugh.. I spent two hours to figure out how to get the time/date to show on the interface and struck out.. Who knows???
