Ultrasonic snow depth gauge

I am thinking of using a Mini-AE myself and tried to get SensComp to send me a quote for shipping to Canada. They couldn’t tell me how much it would cost and whether they can use UPS standard or express, until I put an order in. :?

mikeym, when you say occasional spikes, is that like several times a day? Also, from what I have read, the sensor does not reliably report depths until there is a build up of snow that’s at least several inches from the base?
