It appears to be an expensive lesson to learn, if in fact that you did something "wrong." One potential source of "false triggering" could be debris within the saws housing, say stray aluminium swarf from using the table saw (with suitable blade - of course) to cut aluminium?? or bits from a previous activation???
The "second guessing myself" feeling while you are using a machine like a table saw is a distraction in itself and so is the "waiting for the next bang!" Not good while using machinery as you have created another potential hazard - distraction.
Having the ability to "bypass" the safety features and a fear of more apparently "false" triggering of the safety features will encourage a number of users to simply bypass the saws safety features all together.
I have been a "slow adopter" and have waited until the technology has "matured" with a reasonable history of use and user protection scenarios, false triggering etc, to be generated before making an informed decision.
I also have the added "hazard" of having an implanted cardiac device / defibrillator (ICD) and have asked very specific questions about the potential for the saw stop technology to interfere with the ICD and vice versa. So far the answers have been anecdotal with no hard evidence of any testing. I guess a SawStop will not be on my future shopping list.
As the "sensing" technology used in the Saw Stop is similar to that use to switch touch sensitive lamps it "should be safe" - so not reassuring at all.
ps The main reason that I am hesitant about the Saw Stop sensing technology is that leading manufacturers of ICD's have a clear warning "do not use" for devices such as "Body Hydration Scales" & "Body Fat Analysis Scales" which employ bio-electrical impedance to measure hydration or estimate body fat. The manufacturers of those BHS / BFAS devices have disclaimers in their product literature excluding the use of the product for individuals with a Pacemaker or ICD.
