Humminbird 787 C2i Set-up

[Hoareboy]

HI Guys,
Does any one have some good tips for setting up this type of unit for reef fishing. I have brought the unit with the boat but no manual. Also tips/tricks on how to read it correctly.

with the 83khz on our 787 sounder its not really reading that well as in it is pretty much justshowing red all over or is not reading at all? with the 200khz it reads fine would there be a setting that is wrong or would it be playing up? it plays up in like 20m and over but still can play up below that.

their standard settings or Default settings should be good enough for you to use on the reef straight out of the box.

From there the only 2 real major settings you should touch.

Sensativity - Depending on the water clarity will depend on how high you can have this set.. Higher the better generally speaking. increase the sensativity until clutter starts appearing on the screen, then back it off to where that clutter is only just showing. If it's a perfect clear day you should be able to increase this almost to maximum.. for eg. In a creek on my Lowrance unit i run my sensativity at 64%. Out at the reef i have had it up to 92%.

Colourline - probably just as important as sensativity... This must be set correctly so you can make out whats what under your boat without everything being a big RED mess. easiest way to set it up is to take your boat over what you know is sand and adjust your colourline so you have about 3mm on the screen of a solid red line showing as the bottom. Then go over rocks or reef and you should see this red bottom colour line increase in thickness and even double.

from this you should get a better understanding of your sounder and yes there is a lot i haven't covered, but this should get you in the right direction.
