Accurate Weights for Records and Releases
Tournament anglers need accurate, repeatable weights. Recreational anglers want to know what they caught without guessing. The Rapala RDS100 delivers both with a 100-pound capacity and a backlit digital display that leaves no room for argument.
The memory recall function stores weights from earlier in the trip, so you can compare catches without writing anything down. The tare function is clutch for weighing fish in a wet bag or landing net, subtracting the container weight automatically.

100 Pound Capacity
Handles everything from schoolie stripers to large tuna and grouper. The digital readout provides precise weights without the guesswork of a spring scale needle.
Memory Recall and Tare
Memory recall stores previous weights so you can review catches later. The tare function zeros out the weight of a bag, net, or towel so you get the actual fish weight.
Backlit LCD Display
The backlit display is readable in direct sunlight and low-light conditions. Large numbers are easy to see from a distance, useful when someone else is holding the fish.

3. Hook the fish or container to the scale

How accurate is this scale? +
Digital scales like the RDS100 provide consistent, precise readings. Far more accurate than spring-loaded dial scales, especially for heavier fish. Check our tools collection for more weighing options.
Can I use this in tournaments? +
Check your tournament rules on scale requirements. The RDS100 is a solid portable option for pre-weigh-in estimates. Official weigh-ins typically use certified platform scales.
Does the tare function work with a net? +
Yes. Hang the empty net from the scale, press tare to zero it out, then add the fish. The scale reads only the fish weight.
What should I use to hold the fish while weighing? +
The Rapala Mechanical Fish Gripper clips to the fish's jaw and hangs from the scale hook. Clean, secure, and easy with one person.
Will the backlight work at dawn? +
Yes. The backlit LCD is designed for low-light conditions. It is also readable in direct sunlight, which is where most fish weighing happens.
How do I store previous weights? +
The memory recall function saves weights automatically. Scroll through stored values to compare catches from earlier in the trip. Check the manual for the exact number of stored readings.
