I have some expertise on the Fury Speedo..
Since I've taken it apart 3 times now trying to replace the red led's..
The plastic cover is the problem.
You cannot get it removed without trashing the digital display.
Look at this picture, you can see the flat LED's. View attachment 1747
They are encased under the plastic cover and I cannot get it removed without trashing the LCD display on the right corner. The LCD is encased inside the plastic cover prevent it from coming off.
If someone can come up with a way of removing the pastic cover without damaging the LCD in the process I would like to know.
