Certified GPS?

[RV9APlane]

If I purchase a Skyview system and plan to fly only VFR Day and Night, is there any reason for me to also install a GNS430 or now, the GTN650? I would like to have a two display system, probably 2 ADAHRS, and 2 GPS receivers plus the Dynon GPS Navigation Software, and the Dynon transponder, and a SL30 Nav/Com.  I'd rather not have to drop another 10-15k if I don't have to.  So are there any compelling reasons for me to do so given my VFR only intentions?  Thanks!

If you are in the USA and not flying IFR, then there is not much of a reason to go with a fully certified IFR navigator. Even without the SkyView, something like a handheld GPS would serve you well. With SkyView and the great database we have in the USA, I think you'll find that to be all you need.
