outdoors gift ideas for DAD

i think i finally have an idea for my dad. Im going to buy him the upgrade to the Humminbird 899Ci Di unit that has the details on the lakes in the south.

My only problem is how do i 'implement' it. Anyone go thru it before?

BTW Lil sensei on thanksgiving weekend missed a buck, hit another buck, it fell and kicked..then got up and ran off. Never to be seen again.

Then I took him to Top Gun outfitters in Mer Rouge where he proceeded to lay some smack down on pintails, gadwalls, green wings and shovelers. He shot every bird on the wing.
And he killed a large pintail drake that is now at the 'dermist!!

We are going back after Christmas for more deer...(not sure if i announced on the board in october, but he harvested 2 does). For Christmas I got him a Diamond Infinity Edge bow. he is slightly jacked up to get it.
