I wish I had a dollar for every post on this topic. (here and other sites)
People swear by and at both. I use a spincast usually but here's the math side of the argument...
Retiever reel...$55-65 (slotted reels) 65-75
Arrow with slides...$11
Spincast reel...$20-45
Replacement Line...$? depends on what you use and how much you have to buy.
Reel seat... $20
Arrow...$10
*Replacement arrow 'cuse you forgot to push the button, $10 If it broke the pickup pins on the reel another $20-45 [:@]
Number of times to repeat * depends on your learning curve.
I'll let you add it up for yourself.
That being said, I used a retriever the last time out and kept wishing I had my spincast. Not that there was anything wrong with the retriever, just what I'm used to.
***If you do choose a retriever reel, make sure
all your arrows are fitted with safety slides.***
