Colour differences in bottom readings
Submitted by CC106 on Sun, 2017-02-12 14:36
hi all
Would love to know what everyone's opinions are on the differences in colours on bottom readings are.
I run a Garmin 1020xs and I am still new to the unit, I would like to know what colours are associated with what type of bottom I am reading. What colour does soft coral show up as, sand, gravel etc.

The way it goes with
The way it goes with sounders usually is lighter the colour the softer the bottom and deep dark colours are strong soundings from a hard bottom.

Funny you mention this as I'm pretty sure one of the spots I have pegged up north for Reds has a spongy bottom. It shows a darker colour as its apparently only a thinish layer. I'll have a closer look when I'm up there next time.

Agree with Sea-Kem. My experience is light colours eg yellow are typically sand, clay, mud etc moving to darker colours eg reds, darker greens etc typically reef, rock etc

Tony, is the above based on your experiences with the Northstar product? If so, you have saved me a lot of time in differentiating the colours on navman/northstar sounders!

i might be wrong but
Sponges, ribbon sea grasses would be yellow baseline with light red line mixed in. others might provide a more expert opinion and guidance.
Kev, honestly I dont actually 100% remember what it was on the 650 unit but am reasonably confident it was what I've described ....my lowrance is yellowish soft bottom and red hard bottom, so sure it was the same.

I suppose is jump over the side with a tank on and have a look! LOL. ...probably also wearing a SS too would be the go

I tend to focus on the thickness of the bottom and the 'tails' underneath the bottom sounding.
Sand tends to have a thinner bottom return, reef tends to have a thicker return with tails underneath the bottom sounding.
