Lakemaster vs. Navionics

Same for me. If running the big engine to troll I am going 2-3mph or so depending on the wind. The direction arrow works perfect. If using the TM and going speeds slower than that the directional arrow is a biotch and only pops up here and there which is a pain when one is using the TM to move a little here or there to ones waypoints that are in close proximity.

There is a "fix" but not cheap and more than likely not compatable with your unit. Humminbird released a new GPS puck several years ago that is directional/has a heading sensor. Meaning it knows what direction your boat is pointing even without the boat moving.

This receiver requires software 6.570 or higher in the compatible Humminbird product.

When the AS GPS HS (GPS and Heading Sensor product) is connected to the unit, the unit uses the Heading information (NMEA HDG) from the heading sensor (digital compass) for the boat icon direction and the Heading Line (if turned on). The GPS Course-Over-Ground (COG) always uses COG derived from the GPS output, not the Heading Sensor. The Course Projection Line always uses the COG derived from the GPS receiver. When only a GPS receiver is connected (internal or external) no heading information is shown. The only direction information is derived from the GPS COG information and the boat icon direction is based on the COG, not Heading (HDG).

Simply stated, Heading and Course Over Ground are separate and are not based on speed and when the heading sensor is connected to the unit the boat icon uses the heading information for its pointing direction and it uses the GPS Course Over Ground information for pointing direction when no heading sensor is connected.
