fixing my eagle fish I.D. 2 fish finder

How do I open the plastic case ? Once I have removed the knobs and the only screw what do I do now ? do I use a thin knife and a hammer ? Or is it glued. Thanks John

Hi John.
You will probably find your Fish Finder,like most small power packs etc,are usually thermal welded,or glued,however they can be opened & you have to be careful you don't wreck the case.
The easiest way is to tap around the joints with a small rubber hammer to break the seal,then you can carefully prise the sections apart,with a thin bladed knife etc.
As I've mentioned be very careful,as the cases are easily broken & difficult to repair.
If & when you repair it,you can reseal it with Silicon Rubber.
Also if you have used it in Salt or Brackish Water you will probably find water at some stage has entered & caused corrosion.
Best of luck as you might be lucky.

Thanks Karma. I figured that was the only way. and this was to have been waterproof. I do think water got in and croded the contacks. so again thanks.

Hi John.
I should have mentioned,if you find,a green colouring,(vertigrease)to the joints & soldering on the circuit board,there are some spray paks which will neutralise it,don't try to scratch,or brush it off,as most people do,this can cause tracking,which is in essence means,upsetting the design of the printed circuit,on the board,which in turn,usually cooks the board,&/or its components.
