Review 1 for Humminbird Fishfinder 581i HD DI Down Imaging GPS Combo
Works good in deeper water
By Philthenet ,

Unit works well, GPS is nice feature for marking hot spots and finding way back to launch. Only issues is the screen gets a little cluttered in sallow water 4' or less. Also not a big fan of the mount would rater have plug in cables as opposed to the unit plugging into the mounting bracket. For the money it's a good unit with features of more expensive units.
