I am thinking about picking up a set of shallow water anchors and have been trying to dig in to the details and research different makes & models. The only two brands I can find are power pole and Minn Kota. Does anyone else know of more brands? Not sure if they make a 15 footer, but I am thinking the bigger the better. Any advice would he fantastic, as well as personal experiences and reviews. Thanks guys!

Lol nothing? Awwww...

12ft is the biggest currently on the market.  As far as I know, PP and MK are the only 2 brands. I have a Gen 1 8ft MK. and it has been flawless going on 3 years.  MK's are easier to install (and steal) and take up zero room inside the boat. PP's look better, are hydraulic rather than electric, and use up storage space inside the boat. Both brands come with standard transom mounting brackets. All other brackets need to be ordered separately and they ain't cheap.
