It's worth it to keep your kids. My daughters bought me a set of BlueChart maps for my Garmin GPS (which they also bought for me). With the nautical maps this GPS is a perfect gadget for getting around the lakes, especially when looking for great places to anchor for a day of online work.
With the push of a button I can locate recommended anchor spots close to my sailing location. I can also call up tons of details about the nearby marinas, such as services, washroom facilities, restaurant, and accommodations. I can see myself using this gadget to locate marinas to hang out at for the day.
I especially like the "anchor slippage", a warning that sounds if the boat anchors slip...great if you're "sleeping on the job"!
