Garrett biased opinion:

I would go with the simple baseplate model. I have been using a SIlva Explorer for years. I love how simple it is and it hasnt let me down yet. I have had a few lensatic compasses (both issued and owned( and I prefer the protractor/baseplate model. I even use it in the field. The only thing I cant use it for is to get direction in mils, but for scouts thats not an issue. I like the GPS model you showed, as I use GPS pretty heavily for driving and going on foot, but I always back it up with a map and compass, as I have lost signal before. The GPS model allows you to quickly plot your location on your map for resection or intersection.

So after I spew my opinion, it boils down to what you are comfortable with. If you have been using your baseplate, and you are pretty good at it, I would stick with it. That way you wont have to worry about learing about the new compass and possibly having an issue with it while you have your boys out in the bush with you.

Good luck,

Garrett
