I like my 797 the gps does me well,it get's me close to where I have marked.not hard to use and like the book says It's a nav. tool to help you get close, if you get within 25 to 50ft. of where you are going no problem dont want to run up on the brush or stake beds and scare them fish anyway. they are a good unit. try to go with someone who has one and check it out. personally I like mine and would have another one if I need one. good luck on your choice. also I have a garmin etrex cant tell much difference on the accuracy...
