Review: success every time - I honestly don't know if I'm using this thing 100% correctly. But I've used this to spool multiple reels and I have not had any issues with a rats nest on casting or any other usage really. The price was good and its pretty easy to use. The little elastic bands that go around the spool of line do a pretty great job at keeping tension. I would recommend for those that want easily spool their own reels without having to get too creative.
Review: Great - Works great

## Features

- Key Features – Unique patent pending design - Spool spinning reels and casting reels without fishing line twist – compact design for easy storage and portability – 1/4lb spool capacity – Soft touch clamping points protect rod blanks – adjustable line spooling tension bands ensure that line is spooled tightly on the reel - works with monofilament, fluorocarbon, and braided fishing line.
- PATENT PENDING LIINE SPOOLING TOOL– The innovative KastKing patent pending line spooler design is simple to use and can spool both spinning reels and baitcasting reels without any line twist. Rubber coated clamp points firmly grip nearly any size rod without damaging your fishing rod and tension bands can be adjusted to apply the ideal line tension during the spooling process. Made with non-rusting ABS materials.
- NO LINE TWIST – The Radius design allows fishing line to come off your filler spool and directly onto the reel spool without any twist in the fishing line. When spooling a casting reel, the line comes off the top of the filler spool and winds directly onto the top of a casting reel without changing the coiled memory of the line. For a spinning reel, the line is un-coiled from the filler spool and coiled directly onto the reel spool in the same fashion.
- SPOOLING MADE EASY – Place the tension band on a spool of line, clamp the Radius to a rod, using the threaded t-handle mount up to a 1/4lb spool of line on the tool, attach the fishing line to the reel spool, and crank the handle to fill your fishing reel with your favorite fishing line. Instruction cues are molded into the tool as a quick reference to ensure your set up is correct for spinning and casting reels.
- COMPACT DESIGN – The small design of the KastKing Radius line spooling tool makes it easy to store with your fishing gear at home or take on the road. The threaded t-handle stores inside the Radius and the tension band can be attached to the Radius to ensure all the components are stored together. The Radius is always there when you need to spool line. KastKing Radius Line Spooler compact design easily fits in your tackle bag, jacket pocket, or boat or truck glove box.

## Questions & Answers

**Q: Do they sell extra tension  band**
A: It comes with two, other than that I’m not sure.

**Q: None of my med, med-light rods can get the radius spooler to attach securely as the rods are too thin. is there a workaround for this?**
A: I would use something like the gripping shelf/draw liner and wrapped it around the rod where you want to attach the spooler.  
I would try contacting KastKing also about this. they may have a smaller model, or inserts maybe.

**Q: Will it hold a larger spool?**
A: It is designed to hold larger spools, ie 1000 yards.

**Q: Will this work for smaller rods such as Ice Fishing rods that are very small in diameter?**
A: The spooler is designed to work with a multitude of rods and different thicknesses. It may be necessary on very narrow rods to move the spooler closer to the reel bale where the rods is thicker.

### ⭐⭐⭐⭐ Convenient line spooling tool
*by L***E on November 23, 2022*

Overall I was happy with the line spooler as it is quick to set up, use, and put away. The adjustable tension straps are helpful and keep the line from getting tangled and making a mess. It comes with two elastic nylon tension straps which are decent quality and should last for quite a few years. The scissors work great and the sheath it comes in is a nice addition. The instructions are easy enough to read and follow but I could see how some could find them difficult so watching a YouTube video could work too. The quality of everything is good and I expect to get many years of use from it. I'm happy with this purchase and glad to add it to my fishing gear.
