First saw these guys in London a few years ago. Did get the inclinometer and packaged for dredging application. Used rs-422 and had absolutely no issues. Very simple command set. Alberto Giva, Aqua Positioni.Sra.

Got EZ-COMPASS-3A for our excavator research project. Worked well. This was our choice as it worked on wide range of supply voltages without any additional modifications. Also very easy to use. G.U.

Purchased EZ-COMPASS-4. To all my marine nav friends.You should look at this baby. Small and crazy accurate in such a small size. Jeremy K.

Fast delivery. Professional tech support. Did feel that price was also reasonable. Compass worked well for our application. Small and nifty product. Mark Ortiz, Magna Corp.
