I like the LakeMaster for it's ability to highlight shallow water and the low water level feature. I also have a Navionics card in my Humminbird unit as well and will switch back and forth. It is the best of both worlds.
It's all coming together and we have you covered @ Shut-Up-And-Fish LLC
for all your Humminbird, Minn Kota & Motorguide needs.
We install & educate as well!!! 972 822 9285
