fish finders

Hi there

Just looking for some advice when using my raymarine a65 in water deeper than 80 to 100 meters. Havent been using the bottom lock feature much but talking to someone on the weekend he suggusted that in these depths and deeper if you dont have this on there is just to much information being compressed onto the screen, therefore fish just wont show up. This seems to make sense but havent tried this as yet. Does anyone have any suggestions.

Cheers

You want bottom lock for sure, its one of the features you might buy that unit for.

totally with till on this one. bottom lock eliminates discrepancies caused by swell, etc. mine is focussed on the bottom 5m, as this is where all the fish i target live. its basically a "zoom in" function. you zoom in on the last few meters of the sounding.

its probably the only function i permanantly leave on.

agreed i use bottom lock

agreed

i use bottom lock permanently, at any depth , as it lets you see exactly whats growing above bottom trace  . i also use shift mode on right side set at 15 meters and a scope too.

not too sure on that unit

not too sure on that unit but on the 585 i use 5mtrs bottom and 15 range on right. makes a huge difference when looking around. found some great fish in coral bay using it that way.

Techincally information doesnt get compressed into the smaller screen. With bottom lock you are only looking at the bottom portion of the ocean. It also "flat line" the bottom structure and take away any discrepencies between fish and structure, ie coral and weed.

I recommend using the bottom lock function 20m and over.
If you are not seeing the fish that you'd see on the right hand side then its probably out of the bottom lock range.

Eg bottom lock set at 5m and fish is 8m off the bottom.
