Seriously doubt it. First there is no provision in software to do whatever MG is doing with 2 gps receivers in the MK. I don't have a clue why MG would have two. I assume you are aware that both HB and L have an optional puck that has a built in compass which greatly helps maneuvering to a waypoint....a huge benefit for the way I fish. Price is around $200 and for L it's called Point1 but, I forget what HB calls it.
But, none of this is going to help spotlock!
