What the manufacturer publishes
A chalk line device with a 30 m (98 ft) line for marking on all substrates. A two-component housing, described as sitting very well in the hand. A five-to-one gear ratio, so only a few turns are needed.
Why the winding is the specification
Snapping a line takes ten seconds. Winding 30 m (98 ft) back in takes a minute on a direct-drive reel — and a minute, forty times a day, is most of an hour. What actually happens is that the reel is not wound in: it stays extended, gets walked on, dragged and eventually cut.
Gearing is a durability feature disguised as a convenience.
What to add
Chalk. The listing does not mention any, and the grade you choose — permanent or temporary — matters more than the reel it goes in.

What gets asked here
Does the gear ratio really matter?
Over 30 m (98 ft), yes. Direct drive is a hundred-odd turns; 5:1 is about twenty. That difference is why geared reels get wound in and ungeared ones get dragged across the site extended.
What does "jam free" refer to?
Tajima's name for the line feed. A jammed chalk line means opening a case full of loose chalk on site, which is the failure the name is aimed at.
Is chalk included?
Not stated in this listing. The marking chalk hub in this catalog covers refills.
The only reel here that tells you how big it is — which on a tool that has to fit a belt pouch is the figure that decides it.
Stated dimension or range
100 ft of line, in a box measuring about 5.3 × 3.94 in. It is the ONLY reel on this shelf to publish its own dimensions, and on a tool that has to go into a belt pouch or a drawer that is the figure nothing else gives. No line diameter appears
Material
High-impact ABS, stated as a durable housing guarding the chalk cord against everyday abrasion at industrial jobsites
Body and fittings
A large refill port, stated to make refilling quick. Like six of the nine reels here it describes getting chalk IN and says nothing about keeping it there — this shelf's introduction calls case sealing the thing that decides whether the tool empties itself into a bag
Functions
NO GEAR RATIO IS PUBLISHED. Four of the nine reels on this shelf give none
Also stated
Suitable for wood, drywall, concrete and other construction materials — a substrate list rather than a specification, and the same list as on the maker's own two-pack
Supplied
Chalk NOT included, stated on the maker's related listing. Two reels on this shelf ship chalk and two state it is not included

Ten dollars for a hundred-foot reel
No gear ratio published
Best for: A belt pouch of a known size, and a job where ten dollars is the budget
The only reel here that says how many lines you get from one pull — five or six — and the only one whose spool aerates the chalk.
Functions
FIVE TO SIX STRIKES PER PULL, from 100 ft of abrasion-resistant poly line — stated, and it is the only strike count published on this shelf. That figure matters more than a gear ratio for a lot of work: pulling the line once and snapping five parallel lines off it is five snaps with one rewind
Body and fittings
A 1:1 gear ratio, stated as simple line retraction. One to one is the SLOWEST on this shelf — the others publish 6:1, 4:1, 3:1 and 2:1 — and it is paired here with a robust steel handle and a large center hub stated for durability, strength and torque. Direct drive with a steel crank is the choice that survives a bound line
Material
An Aluminum housing stated for impact resistance. It is one of only two metal shells on this shelf; the rest are ABS or unstated, and a metal case dents where plastic cracks and empties itself
Also stated
An innovative spool design stated to help preserve the line AND AERATE THE CHALK. Aeration is published by nobody else here and it is a real mechanism: chalk packs down round a wound line and stops loading it, and a spool that lets air through keeps the powder loose
Measuring mode
The center line can be used as a plumb bob, stated. It is one of two reels on this shelf that doubles that way — the reel hangs from its own line and marks a vertical from a ceiling point
Supplied
Blue chalk included, stated, in a kit with the reel. Blue is the removable color: it brushes out of plaster and timber where red does not, which makes this a finishing reel as supplied
Reference and mounting
A nested hook dock stated to reduce hook snags, and a wide fill door stated to improve visibility when refilling. A slim profile is stated to enhance grip for low-strain use

1:1, the slowest gearing on this shelf
Best for: Repeated snaps along one run, where the reel is pulled out once and used five times
The only receiver here that publishes how fine it can split the beam — and the only one that admits its range belongs to the laser.
Stated accuracy
TWO accuracy bands: ±1/16 inch (1 mm) and ±1/8 inch (2.5 mm), stated, with the detector directing the user to position the laser higher or lower on the rod. It is the ONLY receiver on this shelf to publish bands at all, and this shelf's introduction lists them as one of five comparisons — a fine band finds grade slowly and precisely, a coarse one finds it fast
Stated dimension or range
A working range of 2000 feet — "depending on laser", stated. That qualification is the only honest one on this shelf: a receiver reveals the laser's range rather than creating it, and two thousand feet describes what a rotary laser can throw, not what this box can do alone
Functions
ROTARY lasers only, and RED only: compatible with most standard red rotary lasers, stated, working in all lighting conditions. It is the only receiver on this shelf that will not serve a line laser, and the only one that will not see a green beam — which rules out most of the cross-line lasers on this site
Display
A dual-sided crisp LCD showing elevation, grade sensitivity, and audio and battery status. Showing the SENSITIVITY on the screen is the detail that makes two accuracy bands usable: you can see which band you are in rather than remembering
Measuring mode
A built-in bubble level, stated. On a detector clamped to a rod that is the check that the receiver itself is not tilted, which would offset every reading by the same amount
Power
A 9 V battery giving approximately 40 working hours, with auto shut-off after 10 minutes of inactivity. Forty hours against about seventy on another receiver here
Ingress protection
IP55, dustproof and water-jet resistant, in a hard plastic housing with a rubber casing. IP55 is the highest rating on this shelf, where the other two are IP54 — jets rather than spray, which on a grading job in the rain is the relevant one
Supplied
A rod mounting bracket with 1/4 inch threading on the nut and screw, stated included. This shelf's introduction asks about clamp fit; 1/4 inch rather than 5/8 means it suits a compact rod rather than a survey tripod

Red only: it will not see a green beam
Best for: A red rotary laser on a grading job, where the difference between 1 mm (0.04 in) and 2.5 mm (0.10 in) decides the fall
The only receiver here that states its range laser by laser — and the only one whose beeper can be turned up for a noisy site.
Functions
Dual compatibility with red and green beam lasers, stated, and the working range given PER LASER: up to 330 ft diameter with the GLL3-330CG or GLL3-330C, 300 ft with the GLL3-300, 165 ft with the GCL 2-160. It is the only receiver on this shelf to state the range laser by laser, which is the honest way round — a receiver does not create range, it reveals the laser's
Measuring mode
An ADJUSTABLE audio signal giving a clear indication of on-grade positioning, stated to adjust to worksite noise levels. It is the only adjustable beeper on this shelf, and it is the feature that decides whether the tone is audible beside a compressor or intolerable in a quiet room. An oversized receiver window is stated for fast reception and finding the center line, and able to catch beams midair
Display
A backlit oversized LCD for easier beam detection in dark or outdoor areas, plus DUAL-SIDED LED arrow indicators for a visual readout on both sides of the receiver. Two faces, where one receiver on this shelf has three
Reference and mounting
A quick-release mounting bracket stated to attach to a leveling rod, plus heavy-duty magnets for metal surfaces. The magnets are the second mounting route and the faster one — a receiver on a steel stud or a door frame needs no bracket at all
Ingress protection
IP54, stated to withstand rainy or dusty jobsite conditions. One receiver on this shelf is IP55, which resists water jets rather than spray
Also stated
Four compatible Bosch lasers are named. No incompatibility list is published, and nothing on the page says that the laser needs a pulse mode switched on — which this shelf's buying tip calls the condition that decides whether the two work together at all
Supplied
The receiver and the mounting bracket. No accuracy bands are published, which this shelf's introduction lists as one of five comparisons
