I believe this is what they call a "flasher" type sounder. When you turn it on you will probably hear something start spinning inside the case and you will see an orange light bar flickering between the center area that says Eagle and the white numbers on the face of the display. This orange light will indicate the depth. Depending on the type of bottom you're over you may see several light bars. I think if the bottom is soft and there is a harder layer below you will see the multiple bars.
I've never used one of these but I remember seeing a demonstration at the boat show one year.
I found unit to be hard to interpret especially in the sun. The flashes seemed to happen in different places on the face and you really had to practice.
Oh ok, I thought there was something wrong with my unit, it seems to work correctly then, If it wasnt in such good shape, I would most certainly have replaced it , but it was on the boat, and I just had to change the transducer, its kinda an unusual piece so I kept it on,
I have one of these. Altho they are old style they are very convenient to read. There are usually two scales. Mostly you would use the 0 to 60 foot scale. You do not have to squint at it to get the feet reading. You read it just like an analog clock dial. So if it is flashing at quarter past you know that is 15 feet. You can set a depth alarm to go off if you wish. I set mine at about 6 or 7 feet. Plenty of warning for my 4 foot draft.
