Codes such as LT2500S-XH, LT3000D-CXH, and FC LT2500S-H-DH describe the size, line capacity, gear speed, body configuration, and handle specification of a Daiwa spinning reel.
This guide focuses on Japanese-market LT and SF reels. Read the code from left to right, then confirm the exact line capacity, retrieve per turn, drag rating, and weight in the specification table for that model.

Read the code in groups
LT and SF model numbers generally combine these elements:
Tune → concept → size → spool depth → body configuration → gear speed → additional handle or drag specification
For example, FC LT2500S-H-DH breaks down as FC (Finesse Custom) → LT (Light & Tough) → 2500 (size class) → S (shallow spool) → H (high gear) → DH (double handle). This longer example shows why it helps to read the code in groups instead of as one uninterrupted string. Other models may use PC before LT or C after the size and spool-depth code.
1. The number identifies the spool-size class
On LT reels, numbers such as 1000, 2000, 2500, and 3000 primarily identify a spool-size class. Spool diameter generally increases with the number.
| LT size | Spool diameter | Typical applications |
|---|---|---|
| LT1000 | 40 mm | Ajing (horse mackerel), mebaring (rockfish), trout |
| LT2000 | 42 mm | Trout, ajing (horse mackerel), mebaring (rockfish) |
| LT2500 | 45 mm | Bass, eging (squid fishing), trout |
| LT3000 | 48 mm | Seabass, black sea bream, main-river trout |
| LT4000 | 51 mm | Surf flatfish, seabass, light shore jigging |
| LT5000 | 54 mm | Shore jigging, surf flatfish |
| LT6000 | 57 mm | Jigging, shore jigging |
These are size and application guides based on Daiwa's published LT framework. Use the letters that follow the number to determine spool depth, body configuration, and gearing. Compare maximum drag and reel weight separately in the product specifications.
Pre-LT codes such as 2506 and 2508PE indicate line capacity
On older Daiwa reels that predate the LT (Light & Tough) naming system, model numbers such as 2506 and 2508PE included a line-capacity cue.
| Older code | Example capacity |
|---|---|
| 2506 | Nylon 6 lb / 100 m |
| 2508PE | PE 0.8 / 150 m |
When comparing an older Daiwa reel with a current LT model, use both spool diameter and published line capacity rather than assuming that similar numbers represent identical capacity.
2. LT, SF, FC, ST, and PC describe the concept or tune
The letters before the size number describe the reel's underlying concept or a use-specific tune.
| Code | Name | Meaning |
|---|---|---|
| LT | Light & Tough | Daiwa's general-purpose concept balancing low weight with strength. |
| SF | Super Finesse | A smaller, lighter configuration specialized for thin line and light lures. |
| FC | Finesse Custom | A compact, lightweight body configuration for finesse applications. |
| ST | Sensitive Tune | A tune emphasizing light rotation and sensitivity, using low-viscosity oil in key bearings and omitting Magsealed protection at the pinion. |
| PC | Power Custom | A larger body than the standard configuration within the same series and size, prioritizing winding power. |
It is useful to treat LT and SF as design concepts, while FC, ST, and PC describe a more specific tuning direction.
SF is designed around thin line and light lures
Daiwa's SF guidance assumes approximately 4 lb or lighter nylon, fluorocarbon, or ester line, and approximately PE 0.6 or lighter. The compact body is intended for precise light-lure control.
The degree of downsizing varies by model. Daiwa states that the Exist SF body is approximately 20% smaller than its comparison LT body, while the Luvias SF body is approximately 15% smaller than its LT counterpart.

The Exist SF2500SS-H illustrates Daiwa's Super Finesse concept and super-shallow spool code.
FC construction also depends on the product. For example, Daiwa's 24 Certate FC models retain Magsealed protection at the pinion. Do not assume that every FC reel uses the same sealing layout.
PC uses a larger body for winding power
Power Custom pairs the stated spool size with a larger body than the regular configuration in the same family. Read PC together with the size and any C suffix instead of treating the number alone as the reel's complete physical size.

PC LT3000-XH uses Daiwa's Power Custom body configuration with extra-high gearing.
3. SSS, SS, S, and D describe spool depth
Letters immediately after the size number identify spool-groove depth and therefore line capacity.
| Code | Spool depth |
|---|---|
| SSS | Extremely shallow |
| SS | Extra-shallow |
| S | Shallow |
| No suffix | Standard |
| D | Deep |
From deepest to shallowest, the order is D → no suffix → S → SS → SSS.
A shallow spool reduces the amount of backing needed when you use thin line. Backing is the line placed beneath the main line to reach the correct fill height. Matching spool capacity to the line diameter and length you actually need simplifies setup.
SSS does not identify a specific line material. For example, SLPW lists its EX SF2500SSS spool at nylon 3 lb / 70 m. The code tells you the spool is extremely shallow; the specification table tells you the exact capacity.
4. C pairs the spool with a smaller body
C means compact body. The reel uses a body one size smaller than the standard configuration for that spool class.
For example, LT3000-C combines a 3000-class spool with a 2500-class body. It keeps the 3000 spool diameter while reducing body size.
PC points in the opposite direction: it uses a larger body than the standard model in the same series and size to emphasize winding power. Read C together with leading codes such as FC and PC to understand the full body configuration.
5. P, H, and XH describe gear speed
Gear ratio tells you how many times the rotor turns for one handle revolution. A 5.8:1 ratio means that one turn of the handle produces 5.8 rotor revolutions.
| Code | Daiwa LT / SF gear-ratio range | General character |
|---|---|---|
| P | 4.9 or lower | Low gear; favors winding force and slow retrieves. |
| No suffix | 5.0–5.4 | Standard gear; balances retrieve speed and winding ease. |
| H | 5.5–5.9 | High gear; faster slack pickup and lure recovery. |
| XH | 6.0 or higher | Extra-high gear; prioritizes even faster line recovery. |
Actual line pickup depends on both gear ratio and the circumference of the line on the spool. When comparing different sizes, also check line retrieve per handle turn in the specification table.

LT2500S-XH combines the LT concept, a 2500-size shallow spool, and extra-high gearing.
Older models and lever-brake reels may use SH for a high-speed gear. Treat that as a model-specific legacy code and confirm the stated ratio and retrieve per turn rather than mapping it directly to the current LT and SF ranges.
6. DH, QD, LB, and LBD describe handle, drag, or brake features
DH means double handle
DH means the reel has two handle knobs. A double handle balances rotation and can help reduce unwanted handle movement after actions such as an eging jerk.
QD means Quick Drag
QD stands for Quick Drag. It allows a large change in drag force with relatively little rotation of the drag knob.
SLPW describes its Quick Drag knob as allowing drag adjustment with approximately one-quarter to one-half turn of the knob. This makes it possible to loosen the drag quickly when a fish surges, using fewer knob movements during the fight. The exact adjustment range depends on the product.
LB and LBD identify lever-brake configurations
LB indicates a lever-brake reel. The lever controls reverse rotor movement, allowing the angler to release line and recover rod angle or body position in response to a fish's pull.
| Code | Meaning |
|---|---|
| LB | Lever brake |
| LBD | Lever brake with a drag system |
The D in LBD means drag-equipped. This is different from the D in a code such as LT3000D, where it describes a deep spool. The surrounding code and reel category tell you which meaning applies.
7. Decode real Daiwa model numbers
LT2500S-XH
- LT: Light & Tough concept
- 2500: 2500 size with a 45 mm spool diameter
- S: Shallow spool
- XH: Extra-high gear
The Daiwa 24 Luvias uses this code. It combines a 2500-class shallow spool with a gear setting intended for fast line recovery.
LT3000D-CXH
- LT: Light & Tough concept
- 3000: 3000 size with a 48 mm spool diameter
- D: Deep spool
- C: Compact body
- XH: Extra-high gear
This code appeared on the 19 Lexa. It describes a 3000-class deep spool combined with a smaller body and extra-high gearing.
FC LT2500S-H-DH
- FC: Finesse Custom
- LT: Light & Tough concept
- 2500: 2500 size with a 45 mm spool diameter
- S: Shallow spool
- H: High gear
- DH: Double handle
The Daiwa 23 Emeraldas RX includes this model. It combines a finesse-oriented body configuration with a shallow spool, high gearing, and a double handle.

FC LT2500S-H-DH combines Finesse Custom, LT, a shallow spool, high gearing, and a double handle.
Use the code to narrow your shortlist
Start with the line diameter and length you need, then choose the size class and spool depth. Next, select the gear speed that fits your retrieve and line-slack needs. Finally, compare body configuration, handle type, drag system, weight, maximum drag, and line retrieve per turn.
The model number is a fast filter, not a replacement for the specification table. Reading the code in groups makes differences within the same Daiwa family much easier to identify.
