Rob Allen Bungee Float Line

The line that saved my $400 speargun from a monster amberjack. Shock-absorbing bungee stretch protects your gear when big fish make sudden moves.
Why This Earned My Trust:
- Saved my shoulder when a wahoo took off
- 20m sweet spot – perfect range
- Quality hardware after 100+ dives
- Handles tuna, dorado, and grouper
JBL Vinyl Float Line

Still using my original JBL line from four years ago as backup. Proves you don’t need to break the bank for reliable gear that works.
Budget Option That Works:
- Lightweight vinyl construction
- 15m perfect for reef diving
- Tangle resistant design
- Fits any gear bag easily
Neptonics Pro Spectra

Watched my buddy land a 40kg yellowfin with this. Spectra core stronger than steel, lighter than most lines. When failure isn’t an option.
Professional Grade Features:
- Spectra core – stronger than steel
- 30m range for serious depths
- UV resistant in tropical sun
- Professional crimps tested to spec
From my experience, 20-25m covers 90% of diving situations. Take your max dive depth and multiply by 1.5. Diving to 20m? Get a 30m line. Too short is way worse than too long.
You could, but when a 30kg tuna is testing your setup, you want professional-grade connections. The crimping and hardware quality on commercial lines is tested to specific breaking strengths.
For beginners and safety, float lines win. They’re simpler, more reliable, and make you visible to boats. I’ve used both extensively β reels can jam when you need them most.
