Dive Reel for Anchor line question..

Hi Guys,

I need a dive reel to hold my line while fishing on anchor.  I saw these.  Any experiences on them or something similar would be appreciated.

Interesting... I don't know much about the usual use for a dive reel, but I'm curious about the breaking strength of that string. The string's breaking strength would also be an indication of the plastic's breaking strength.

I got the idea here.
