I am overly redundant on navigation tools, I carry a Inreach Mini 2 and Garmin GPSMAP 64sx that both pair with my Instinct watches and phone. To me its worth the weight to have a completely separate handheld. Bass Pro/Cabelas has the 64sx on sale for 229 right now.
The best deal around if youre looking for a handheld with inreach capability, S&S has some return 66i's on sale for 299 in their sale section. Normally a $600 unit.
