Topic: TM 360 Water Column

[kev-o]

I just  had this installed on my boat and yesterday was the first time I could mess with it, I noticed that the water column was very small in shallow water and it got wider in deeper water. I was reading the operation manual and it said that water column width will vary depending on the depth of the return. I'm just making sure that it is working properly.

Thanks,

The water column width indicates the depth of the water just like it does on a SI unit.
