With the 18MZ you can set a Shaker (4 different vibrate modes) I use it for my Vne(never exceed) on the Eurosport telling me to slow down.

What the 18MZ does not have is an alarm duration. Once it gets to the setpoint high or low it goes off and continues to sound either with voice callouts or vibration. I just found it a little annoying as it was going off all the time during taxi. Also it was more helpful to go for a target airspeed on approach. Certainly not to slow but also not too fast. In all the full scale approaches I've shot I've rarely set the horn off but was still constantly monitoring the Airspeed shooting for 140knots to the Outer Marker 110 during the final approach and then 90 over the fence.

Undoubtedly this type of device would be great just as a stall warning device. Wow that would save a lot of guys from some very sad days. Stalls have got to be at the top of the list as RC Jet Killers.
