Chronograph recommendations

[Ryry]

Looking to get a new chrono and want some feedback on what models to look at and the ones to stay clear of.
Thanks for any feedback

The oehler is arguably the best on the market, but it still depends on light..I have one and want a magneto, I have been around the magneto a bit and like it.

Question. The V1 , as I read it should be able to handle a 12 gauge Rem 11-87 correct?
