I have two separate setups using my Deus 2, one using the remote set up with the 11 inch coil and one set up with the puck using the 13 inch coil. The remote with 11 inch coil is my go to detector, but today I went with the puck with 13 inch coil. I am on the beach at 430am and found out that the puck has no backlight to light up the display. I know I could just use a flashlight or headlight but for a $1600 detector is that asking too much. I guess to much of a power drain on the puck would be my guess, anybody know why?
