[Aluminum JOG power lever]

The new Seaborg Jog Power Lever system is designed for standup fishing techniques. With the standing fight concept in mind, the Jog Lever will allow an immediate response to wind the line. When standing with the rod/reel outfit in your right hand the lever can be controlled with your left thumb. Alternatively when using your left hand to hold the outfit, pinching the lever with your right hand will allow you to control the machine easily. This easy to use function will allow you to continuously lead the fight against your target.

[MAGMAX motor]

 The strength of Seaborg’s new custom motor is in the same class as the mighty Marine Power 3000. The power and speed are quiet and smooth, and with an output of approximately 1.3 times greater than previous motors. This is the ultimate battle machine. With all this power, the new aluminium composite housing is designed to maximise the release of heat and keep the motor cool, ensuring that the power is available all the time. This monster has a tough heart inside, to challenge any fierce battle in the sea.

[MEGATWIN-PRO]

Daiwa’s original Seaborg Megatwin reel design utilises a two-gear ratio system. The new Seaborg employs a totally redesigned system that allows the user to immediately switch between mega-power mode and mega-speed mode by simply touching a button. During retrieve or when battling a monster the new speed function switches smoothly and effortlessly. With this functionality, an angler can alternate to the best speed, depending on the situation.

[Fall brake dial]

・Brake system that can instantly set the device falling speed by dial operation.
※It is possible to adjust from MIN to MAX (* sticker 1 to 10) at about 180 degrees.
In addition to preventing backlash, stable drop speed control can improve bait attachment in drop fishing and capture the touch of squid during the fall.
※Accessory: Attachment of guideline sticker

[Dot Screen Display]

Out in the field it can be tough to read anything on an LCD screen due to sun glare or sunglasses. The Seaborg’s LCD screen displays large letters/numbers and uses a dotted LCD screen to make it easier for anglers to see the display. Line input procedures are selectable in Japanese or English languages. Just let the D-Vec letters on the start screen lead you to the exciting world of Dendoh reel fishing.
