I will need this initially for connecting rod bolts while under the vehicle. I'm sure I will use it for other tasks but will need it primarily right now for the rods. I keep seeing the OTC, but I don't mind spending a little for a higher quality gauge. I like the dial gauges since there's less to go wrong, but some digital gauges have great reviews. I never wanted to rely solely on a magnet mount digital gauge but I've never used one so I cannot base much on my thoughts. The thought of breaking a rod bolt when trying to change a bearing makes me want to spend a little on a quality gauge. All input appreciated.
