I like the Garmin GPS/Chartplotters. The land countours are not 100% as it will occasionally show your route over land but I have seen the same error on my new Lowrance. I have the 192C (about the same features as the 182)on the Whaler and had a 2006C Garmin w/Depth Module on another boat. WAAS helps GPS accuracy and has never let me down to get within a few feet of my target. Bluechart maps are pretty good, there are probably better systems out there now but 10 years ago the 182 was pretty high end. My brother-in-law uses the 160 Blue Fishfinder, he likes it for the simplicity and cost and it works well for him in the shallow waters around Tampa Bay.
