Hi Jeremy,
Navionics is the same as “hot maps”.
This chip covers a six state region. (North Region)
The Lakemaster Pro Map chips are more state specific
with the exception of LOTW and Devils Lake ND.

Navionics will cost you more but you do get more info.
Navionics offers a Trade In program, Lakemaster does not.
You can zoom in closer with the Lakemaster chip than with
the Navionics which can really help find those fish holding
areas.
I can’t remember what the zoom difference was between the two.
I sold my Navionics chip awhile ago.
If you can swing it buy one of each!!
Good Luck,
Dan
