What each page actually publishes per size
Before comparing values, check which fields exist at all. We read four current spinning reel pages and recorded whether each number was given for the selected size, only for the range, or not at all. [1] [2] [3] [4]
| Field | Piscifun Carbon X | KastKing Sharky III | KastKing ReKon | PENN Battle IV |
|---|---|---|---|---|
| Price by size | Yes [1] | Yes [2] | Yes, by size and color [4] | Yes [3] |
| Gear ratio by size | Two options, 5.2:1 and 6.2:1 [1] | 5.2:1 on all sizes [2] | Yes [4] | Yes [3] |
| Max drag by size | No, up to 33 lb [1] | No, up to 39.5 lb [2] | Yes [4] | Yes [3] |
| Line capacity by size | No [1] | No [2] | No [4] | Yes, mono and braid [3] |
| Weight by size | No, one 5.1 oz figure [1] | No [2] | No [4] | No [3] |
Catch a range-level number before it reaches your comparison
A range-level number describes the best or biggest configuration. Piscifun gives the Carbon X a single weight of 5.1 oz and a single drag figure of up to 33 lb, while selling it from size 500 to 4000. [1] A 4000 cannot weigh what a 500 weighs, so neither figure belongs in a 3000's row.
Compare with PENN, whose table gives the Battle IV 1000 10.8 lb of max drag and the 3000 15 lb. [3] That is the level of detail you want for every candidate. When a page cannot give it, the honest entry is unknown.
A worked example at size 3000
Suppose you are choosing a 3000 for bass and want about 150 yards of 10 lb mono. Here is what the pages let you fill in on the access dates. [1] [2] [3] [4]
- Only the Battle IV row is complete, and it costs $95 to $105 more than the others.
- For the three budget reels, ask the seller for capacity at your line test before ordering, or accept the risk knowingly.
Check these fields before checkout
- Full model code and size, plus handle option where offered (the Carbon X 500 and 1000 come in ordinary and folding-handle versions at different prices). [1]
- Anti-reverse: Piscifun says Carbon X sizes 500 and 1000 have no anti-reverse switch. [1]
- Capacity for your exact line test, with the header order checked.
- Max drag for your size, or a note that only a range figure exists.
- Return window and condition: Piscifun allows 30 days from receipt for unused items in original packaging, with authorization, and buyers pay change-of-mind return shipping. [5]
- Warranty start and proof: KastKing counts one year from purchase at an authorized retailer and asks for proof of purchase and photos or video of the fault. [6]
Keep a working reel unless a field fails
If your current reel holds enough of your line, has the anti-reverse behavior you use and has not failed, a new headline number is not a reason to replace it. Spend when a specific field fails: capacity too low, wrong size for the rod, or a mechanical fault.
We have not handled, spooled or weighed these reels. All values are seller specifications copied on the access dates shown, and sale prices change often.
Questions before you decide
Which spinning reel specs matter most?
Line capacity for your exact line test, the size that fits your rod, and drag and weight for that exact size. Bearing counts and range-level headlines matter less.
What if the product page does not list capacity by size?
Record it as unknown and ask the seller before ordering. The Carbon X, Sharky III and ReKon pages we read did not list capacity by size.
Can I return a reel after spooling line on it?
Under Piscifun's policy, used items cannot be returned; returns must be unused and in original packaging within 30 days of receipt. Check the reel before spooling.
