Daiwa Seaborg 300J Electric Reels 2026
Daiwa's new Seaborg 300J takes the ache out of deep water. Where hand-cranking up from 1,000 feet leaves your shoulders wrecked the next day, this compact electric does the lifting, and at just 570 g (about 20 oz) it stays light and sensitive enough to fish hand-held all day. Off our coast that means dropping deep rockfish, reds, and lingcod without the workout, then switching to electric jigging for yellowtail and tuna on the same reel.
Power that lasts
The MAGMAX-G motor is the heart of it: strong, fast, and built with roughly 4× the durability of the previous MAGMAX, backed by a 3-year motor warranty. It fishes depths past 1,000 ft with ease and has the torque for slow, loaded lifts. The JOG POWER LEVER puts all of that under your thumb: a gas-pedal dial you feather with one hand while the other stays on the rod, so you can play a fish the way you would on conventional tackle.



Drag, gearing, and hand feel
The ATD carbon drag delivers a max of 35 lb (16 kg) with a smooth, shock-absorbing start that keeps light line honest. Cranking by hand, HYPERDRIVE DIGIGEAR keeps the 6.3:1 gearing turning smoothly even under load, 87 cm (about 34") per handle turn, and Infinite Anti-Reverse means no backplay on the hookset. A MAGSEALED ball bearing on the spool shaft holds off salt and grit right where corrosion tends to start.


Dialed-in electronics
A large dot-LCD counter stays readable in glare (meters or feet, nine languages), paired with a thumb-set fall-brake dial for drop speed, depth alarms, and a built-in jigging mode that runs three auto-jerk patterns hands-free. The thick-leader level wind passes an FG knot of PE5 braid to a #30 (roughly 100 lb) fluoro leader through its 3.0 mm aperture, ready for real tuna and yellowtail leaders, and the 70-80 mm handle arm adjusts between quick retrieve and maximum torque.


Right- or left-hand
Choose right-hand (SB300J) or left-hand (SB300JL) above. Like any electric reel it runs on a 12-16.8V DC battery. A Daiwa electric-reel battery is recommended (it will not run on household AC or 24V boat power).
