What is electronic float ?

This uses super-light lithium battery which has highly dense energy. It has long life and you can turn it on or off. It is echo-friendly and will replace chemical float which emits light from chemical reaction.

Advantages of using electronic float

· Highly dense energy (800wh/I)

· Can be used under a wide range of temperature (-40°C~70°C)

· Ideal operating voltage (3V)

· Long period of energy storage (more than 5 years)

· Lowest discharging rate (discharging rate: less than 1%/year)

· No leakage and good reliability(3years Warranty)

· Echo-friendly product which is free of heavy metals

BR TYPE: Lithium battery (Used for bobbers with built-in LED)

It has diameter size of 3mm, 4mm and 5mm There are different lengths for each diameter size. So you can choose the size you want. You can replace the battery in the bobber. [Voltage] 3V [Application] for fishing in plain water and in salt water

R type: Lithium battery with built-in LED (LED is built-in. Just attach the battery to the bobber.)

It has diameter size of 3mm and 4mm. There are different lengths for each diameter size. It has red, yellow, green, and pure-green colors. So you can choose the size and color you want. You can also turn it on and off. So you can use it longer. [Voltage] 3V [Application] for fishing in plain water and in salt water

JR TYPE: with separable LED light (Lithium battery and LED light are separable. Then can be assembled together when it’s used.)

It has diameter size of 3mm, and 4mm. There are different lengths for each diameter size. When the battery is dead you can replace it with a new 2A battery.  You can also turn it on and off. [Voltage] 3V [Application] for fishing in plain water and in salt water
