You may want to grab yourself an extra SD card, so you can backup the waypoints eventually, 256-512 meg is way more than enough. In case you ever need to reset the unit, which clears the memory.
The only thing I change is shells. I don’t ever change chokes from ducks, to geese, to snows, to turkey. I know many people do, but I stick with my 3 1/2 870 XCS with extended Pattern Master. That choke flat out whacks heads, and am most experienced and efficient with the good ol bead at the end
I bought my Stoeger M2000 to be a dedicated turkey gun, but it points so naturally for me and is so light, I use it for pheasants too. When turkey season rolls around, I change the choke, put on tri-viz sights, a v-pod shooting stick, and a sling and I am ready to go.
