Thanks for all the info eveyone. I guess I should have figured on finding some knowledgeable compass folks around here! Looks like I'm probably better just sticking with the baseplate compasses I currently have (or maybe upgrade a bit). Sounds like the lensatic I was originally looking towards might be a more specialized model and not quite so good for general navigation compared to other types (I think I already knew that - and everyone here just reinforced it). I still may try one someday.
