Any ideas for a troublesome sounder??

hey everyone were having some sounder troubles the souder is a furuno LS4100  

 

the problem was my grandad for the 1st time with this echo sounder(we havnet touched any settings) went to try toi locat a spot in roughly 50 metres and around 25k's out.

 

the echo souders problem was it would go to a max of 45 metres roughly and not show any deeper or any rocks/strucre/bottom type etc just one long straight line 

it works fine in shallower water

 

and he certainly went deeper than 40 metres as he eneded going out maybe 45-50 km out so that eliminate that possibility

 

so what settting do we have to adjust??, not a lot of experience with echo sounders

simple like that but

 

he like all the others from his generation suck with electronics hah so he doesnt know anything about the sounder and i dont know anything either lol

 

so i think all i have to do is press that +/- sign with "range" on it

 

i'am sure thats the prob

 

just can get annoying for the first time in 25 years he goes out there looking for a spot friends gave him and the souder stuffs up.

 

and plus he ended up 20km further out than he intended haha
