Helmet Intercom

[Nick]

I purchased the Terratrip Terraphone Intercoms.  I’m sure that it’s a great intercom for rally use.  The microphones and speakers (two per helmet) appear to be high quality.  All three should be velcro’ed in each helmet.  Their cables are coiled (a good thing) and use large headphone jacks (another good thing).  The main unit is 5�?x3�?x2�?, a compact size to be mounted in a car, but a little bulky for an Instructor to carry from car to car.  The unit requires a 12 volt power source so there are no AAA batteries to replace.  I am in the process of adding a cigarette lighter adapter to the power cord. 

 

Having a student with this device mounted in her car with the speakers and mic mounted in her helmet would be a dream come true.  Carrying the unit from car to car, plugging it in the lighter and fishing the wires through her helmet is less desirable.
