The Fox Digital scales are more compact and light than most other scales while also having a bright display to easily weigh fish in the dark. The scales have an on/off switch to maximize battery life. The operation is simple: press the button to set to 0.00, press once after confirming the weight of the wet weigh sling and you can weigh your catch. The Fox Digital Scales features a metal ring at the top for use with a weigh bar and a large hook at the bottom to attach a weigh sling.
