Daiwa Seaborg Dendoh Electric Reel 500MJ

Daiwa Seaborg Dendoh Electric Reel 500MJ

Why you need this:

The Daiwa Seaborg 500MJ is the electric reel for anglers who want compact size without giving up deep-drop power. With Magsealed bearings, 70 lbs of drag, and Mega Torque motor technology, this reel is built to dominate Alaska's deepwater species — from halibut to black cod to lingcod. Whether you're dropping 500 ft off Montague or fishing the canyons for rockfish, the Seaborg 500MJ gives you the speed, strength, and control to bring up the big ones.

• Compact size with serious torque
• 70 lb drag — one of the highest in its class
• Mega Torque Motor: fast, quiet, and powerful
• Jog power lever for precision retrieve control
• Magsealed bearings protect from salt intrusion

What’s this good for?

Targeting deep-sea halibut, sablefish, lingcod, and rockfish
Jigging or bait fishing in 300–800 ft+
Fishing solo or reducing fatigue during long drops
Electric assist for older anglers or multi-day charters
Compact boats where space matters

How to use?

Mount to a heavy-duty electric jig rod
Spool with 80–100 lb braid
Connect to a 12V DC power source (battery or onboard)
Use the LCD display and jog power lever for drop depth and retrieve control
Perfect for hands-on or hands-free operation

Why we love this one:

The Seaborg 500MJ packs serious muscle into a surprisingly small reel. It’s loaded with tech — from the waterproof Magsealed internals to the programmable autostop and digital readout — but still feels like a traditional reel in your hands. This is the reel for Alaskans who want power without the bulk, and tech without the complication.
