So I've decided to bite the bullet and purchase a nice Kebiki gauge. It seems that as time goes on, they are harder to come by. I'm looking at those carried by Suziki tools. They sell the 150 mm with double locks and the 150 with magnet.
I've never heard of the magnet one, and so was going to go for the double locks. However I wanted to ask whether anyone is familiar with the magnet version of a Kebiki. Any reason I should choose one over the other?
