I drive by and mark structure aproprietly.
Then go to the front of the boat with a identical networked unit and try to navigate to that location.
My unit starts twisting and turning the map, if I change the direcetion (IE North always up or heading always up or whatever) it creates another twisting and turning of the boat icon. My refresh rate is already at max (1 second).
I have read to have a true GPS bearing you must have three points of intrest not just the one within the Lowrance unit. In reading how spot lock works on my Ipilot it mimicks a three point intrest then spaces itself X number of feet from each and corrects itself as needed.
Does anyone have working knowledge of and if so WTH?
I have added the external GPS puck and it is no better response than the internal puck.
Is this the best I can expect from 5k in electronics?
