i have three compasses: a lensatic, a baseplate, and a little baseplate like compass made by SUN that i wear around my neck on a daily basis. now i have heard that the lensatic is not all that reliable because it is not liquid filled. any thoughts on this? i like the SUN compass because i can wear it as a necklace as i said, and the basseplate i keep in my edc bag. can anyone re3commend a decent inexpensive compass to carry at all times?
