Thread: Explain This

Something about the water and the ducer. Clean the transducer and then wipe the water over it when you first put in the lake. Can't remember where I seen that but worth a try. Ferdi

Greg explains "Max Depth" better than I do ...

In or out of the water the transducer will ping. However, if it is not getting a water depth reading it will wait for the maximum amount of time before it pings again. It has to do this in case it really is in very deep water. Setting the Max Depth menu will limit the unit in the amount of time that it will wait to ping again – depth reading or not.

With the Max Depth reading set to “Auto” it will adjust to the depth at hand if there is a water depth to be detected.

In 2d, I sometimes get double the depth readings in water <10' and certain bottom types on both my 788 and 988, but I have never seen it show on the water column on side image view. There must be something different with ping rates in the two views.

Turn down the sensitivity if everything else fails.

It would be worth a shot to turn down the 2D .... Seems to be reading exactly 2 times the actual depth and it may think the 2nd echo is the depth.

Ok! I'm a newbe here, but I think I can help. The lines on the image are "range" lines not depth. HB si pings straight down and to the sides 40 feet from Your boat. The boat is over 22.5 feet of water. The period between 22 and 5 is 30 feet to the left of boats path. Part of the school of fish are 10 feet to the left of boat's path.
