If you can afford one I highly recommend one.Especially if you are an old man like me.
When i fish alone it is a bummer for me to run and set my anchor.Sometimes i get great anchor pullers but then again that is hit or miss with newbees.One time i spotted a big school of reds.Cut the motor drifted in range and told the anchor puller set the anchor.I turned around to grab a rod and heard this big splash.Dummy sailed the ancher about 10 feet and ran every fish off for two miles.
I decided that i needed a better way to anchor.The PP is just great.Tell the Wife your back hurts and that you will have to give up fishing.Do not be surprised if her Boy friend buys you one LOL 
Well maybe
That’s because you pick bikini-wearing anchor tossers, Joe - - you gotta choose; fishing buddies, or you-wishing buddies!
