G'day morpheus,
The 700TE is a great reel - it'll do a fine job of jigging.
The ratio (4.7:1) is relatively high, but in the right range.
It's also got a good-sized handle, which can be a real bonus over a day of jigging.
Unlike specialist jigging reels like the Saltiga Z40 (

Otherwise, it's spot on.
Good luck, Justin
