The GPS puck with a heading sensor was released when the 360 sonar got released. It is required/needed for that sonar system to work properly/be displayed correctly on the screen (I'm about 98% sure on that analogy).
If one purchases a system that has a "normal" GPS puck (typically the Humminbird 800 series units and above) you can send in that puck in it's unopened/never been used condition plus the $$ difference and maybe shipping, I can't remember all the exact details, and get the upgraded version with the heading sensor. So really only a $50 buck or so upgrade if one has the "normal" puck in never been used condition. (At least Humminbird use to do that stuff. Haven't checked into it for years. One use to be able to send anything in in never been used condition for a upgrade/change. Like changing up a transom mounted transducer that comes oem with a unit for a trolling motor mounted version, etc.)
Just like I have mentioned before I couldn't imagine running that lake without a map/GPS I really have no desire to have a system with mapping w/o a separate GPS puck. When I mark my waypoints I want the mark exactly where the item of interest is. Thus my GPS puck is mounted on the back corner of my boat as close as possible to the location the transducer is at. That way no matter what direction I come from to the waypoint once my GPS says I am there I am there since the mark is exactly where the transducer is at that saw the item I am looking for. Works especially well from the front of the boat too. If I mark something with the console unit the mark is exactly above the item of interest (below the big motor per se). My front unit is internal GPS so when the front unit says I am there the spot of interest is right under the bow of the boat where that unit is at (I can see front/rear waypoints on both units since they are connected together via a Ethernet cable). Small differences but in all reality can make a difference. Trying to get exactly on top of a rock pile for example if I wasn't set up the way I am I could be 16 foot away from the item or more.
I know lots of babble. I think I made sense. I'm just a little detail oriented now and then [cool]
