General Mach Discussion / Re: Hall Effect or Slotted Opto?

Agree with Russ. The Hall's are more expensive, make sure you look at the specs as some have faster repsonse than others. The Hall's are easy to mount and align so you can get away with an installation that otherwise couldn't be done. The rare earth magnet I used was only 1/8" dia x 1/16" thick and was grazy glued to a pulley.
BTW, you only can use one / single slot and there is no advantage to multiple slots.
I don't use a BOB. Mach's rpm is good to probably 4 places is probably more accurate than your indicator.
RICH.
