Momoi Hi-Catch Monofilament Leader

Momoi Hi-Catch is the leader material you'll find on tournament boats from Montauk to the Keys. It's dead clear in the water, has almost zero memory straight off the coil, and handles serious abrasion from bill wraps, reef edges, and toothy fish. The strength-to-diameter ratio beats most competitors at the same price point. We stock 18 sizes from 20lb up to 400lb test, so you can rig everything from light sailfish leaders to heavy marlin wind-ons. Each coil gives you enough material to build multiple leaders without running short mid-trip. If you burn through leader material on the water, this is the most reliable bulk option we carry.
  • Crystal clear with near-zero visibility underwater
  • Low memory straight off the coil
  • 18 sizes from 20lb to 400lb test
  • Superior abrasion resistance for bill wraps and reef contact
  • Made in Japan by Diamond Fishing

Better than advertised

I didn't really know what to expect as I usually get my sinkers at a beachshop. These were better. Clean and new looking as if just pored. Very satisfied with my purchase!

Epic Fishing Co Deep Drop Weights - Hand-Poured Lead Sinker - Tilefish Grouper Snowy
David F.
Perfect measurements and weight

Used this differently than its intended design. I made raft oars counter balances from them. Previously used steel 4lb mounted on the exterior near the grips. These I was able to install into the shaft and at 5lbs was able to get the weight away from the grips. Both oars took about 30 minutes. Another bonus is the seller got the weights to me in 4 days vice 12 Amazon predicted.

great bonito bait

Used these jigs this week and crushed the bonito on the east coast. This is a good bait to mimic the small bait fish in our area. Also great pack for a 2 pack. I bought a few different colors.

Clarkspoon Shad Jigs - 2 Pack Bucktail Jig - King Mackerel Bluefish Inshore Fishing
Brad B.
Awesome bait for Hybrid striped Bass.

Purchased these and first trip out boated several very nice Hybrids. The fish were in 5-7lb range. The bait falls fast and the hooks are very sharp for solid hook ups. Glad I had an extra one because I gave it to my buddy in the boat and he immediately hooked up. These baits worked so well, I ordered several more. I also referred several of my friends to the site to order this bait.

Build Leaders That Win Fish, Not Lose Them

The difference between a tagged fish and a cut-off usually comes down to leader material. Momoi Hi-Catch has been the go-to for serious offshore crews for over 30 years because it does one thing perfectly: it stays invisible and stays connected. You get the strongest knot strength in its class, clarity that fools pressured fish, and enough toughness to survive the chaos of a hot bite. Stock up once and you have leader material for the entire season.

Crystal Clear Visibility

Momoi's extrusion process produces a leader with optical clarity that disappears underwater. In 80lb and 100lb test, it's noticeably clearer than Jinkai or Ande at the same diameter. That matters when billfish are picky or the water is gin clear.

Zero-Memory Coils

Pull 6 feet off the coil and it hangs straight. No heat gun needed, no stretching required. This saves 5-10 minutes per leader build compared to stiffer materials, and your finished rigs present baits more naturally in the spread.

Abrasion Resistance That Holds Up

Hi-Catch handles bill wraps, gill plate contact, and reef scrapes without nicking through. The outer surface is harder than standard mono but the core stays flexible. We've seen 200lb test survive 3-4 blue marlin fights before needing replacement.

Specs & Common Questions

Everything you need to know before you buy

Full Specifications +
Material Monofilament
Test Range 20lb - 400lb
Color Clear
Manufacturer Diamond Fishing (Japan)
Memory Low
Spool Type Coil
What pound test Momoi Hi-Catch should I use for sailfish? +
Most anglers run 60-80lb test for sailfish leaders. That gives you enough strength for a bill wrap without spooking a fish on the bite. Check our trolling spread guide for leader length recommendations by species.
How does Momoi Hi-Catch compare to fluorocarbon leader? +
Hi-Catch mono is softer, cheaper per foot, and easier to crimp than fluoro. Fluoro has a slight edge in refraction but in most offshore trolling situations, mono works just as well. We carry both options in our terminal tackle collection.
Can I use this for wind-on leaders? +
Absolutely. Hi-Catch in 80-130lb is the standard for wind-on leaders on 30-80 class tackle. The low memory makes it easy to build a smooth connection. See our rigging guide for wind-on construction steps.
How much leader material do I need for a season? +
For a typical offshore season, figure 2-3 coils if you fish 20+ trips. Each coil builds 8-15 leaders depending on test and length. Grab the 50 yard spools if you want a smaller quantity to start.
What's the best knot for Momoi Hi-Catch? +
A 5-turn improved clinch or uni knot works well in lighter tests. For 100lb+, use crimps with double barrel copper sleeves. Our ballyhoo rigging guide covers crimping technique in detail.
Is this the same as Momoi Extra Hard leader? +
No. Hi-Catch is softer and has lower memory. Momoi Extra Hard is stiffer and better for hook rigs where you want the leader to hold a shape. Hi-Catch is better for general trolling leaders and wind-ons.
Does it work for bottom fishing leaders? +
It works but it's overkill for most bottom applications. Hi-Catch really shines in trolling and billfish rigging where clarity and low memory matter most. Browse our terminal tackle for bottom-specific options.
How should I store Momoi Hi-Catch? +
Keep it out of direct sunlight. UV degrades mono over time. Store coils in a tackle bag or drawer and they'll last 2-3 seasons easy. Read our trolling spread article for more leader care tips.
