OCS-70 Memory function -- 75KG Waterproof Digital Fishing Scale with aluminum hanging rod for Fish Tournament

This's a waterproof fishing scale , a new developed product produced from my factory.

Not only can it be submerged for six hours and still function properly, it can also store 50 weights. Because there is an IC for storing weight inside the product than the ordinary fishing scale parts. The weight can be stored in any of 50 locations and can be queried and deleted at any time.

There are four buttons and two units, and the important thing is the memory button.
You can store the weight anywhere in the IC and pull it up when you need it.
Then press the save button to save the weight to any key, press the Memory button to select the sequence position you want, you can also press the unit key to delete the weight you do not want after storage. The stored weight can be adjusted when you need it.

Finally, press and hold the switch button to shut down!
