I bought and installed a Lowrance Mark 4 depth finder and chart plotter on my boat.  All the reviews with the exception of one were favorable.  Does anyone else have advice about my new toy.  I do realize that it is obsolete, but it was not too expensive, and I have had good experience with Lowrance products in the past.

 

 

 

 

 

The Mark 4 is a good unit at its price point.  Here are some sonar settings to get you started.  First, put the unit in Advanced Mode.  Select the Shallow Water (< 60 feet) fishing mode.  Keep unit in Auto Sens. and Auto Depth, and run it in 200 kHz.  Set Ping Speed at Fastest.  I prefer the color white w/ bottom track.

Thanks, I will do that.  I plan on trying it out tomorrow afternoon.

Ignore my comment about sonar color palette.  I was thinking Elite series units when responding and forgot you had the monochrome Mark unit.

I love it!  For  two hundred bucks you can't beat it.  The GPS seems to work good.  I know it is obsolete, but it is way more advanced than what I was using.  The map seems fairly well detailed for an entry level product.

Thanks for your input Todd.
