Garmin 120 Fishfinder

[diverdad]

Hello all, I have a question; today I have been out on the sea in the best conditions so far this year. I went to dive my favourite wreck from my RIB for the 1st time. I arrived on the scene and was not able to locate it just a flat sea bed at 45m, nothing, nada, didley squat.

Luckily for me and my dive buddy we had another rib shadowing us on his 1st ride out of the year. I gave him the numbers and he was straight on it.
I dropped a shot line in and went over it..... nothing, just a flat seabed!
The wreck stands 4m high and 80m long.

I had a fiddle with the menu but nothing seemed obvious and still no joy.

OK, buddy and I kitted up went down and had 45mins on a huge wreck in tropical 6 degree water.

The thing is accurately giving sea bed depths at all levels but not the rusty stuff.

Is the clue in the name "fish finder" does any manufacturer offer a "wreck finder", (joke)!!

My question is (serious now), am I missing something, (menu item etc)?

Constructive replies appreciated.

Thanks in advance.

Hi Lee
have you used the zoom function - at 40 m zoom at 4x is ideal - basically this will show the bottom 1/4 of the depth and any bottom trace (inc wreck) will look 4x taller on the screen
Dont use the split screen
Hope this helps - but you may have tried this already.
Just one other thought - is your transducer horizontal ?
Out at Whitby todat - spookily smooth wasn't it !

Hi Jeff, thanks for the post, the transducer was one click from horisontal so I have put it straight.
I am out next Sunday so I will have a look at the zoom functions etc.

Thanks again
