You might be right, its probably where the PA4x gets deeper then the T5, where the operating becomes more advanced, The Tyros5 is a snorckling instrument, and the PA4x can do that to... but when scubadiving, the PA4x could become a little more confusing..


I also have to come back on my orriginal statement, as i missed the whole collection of instruments Bernie allready hsa, including the S970.... which makes the pa4x only the most naturall choice to make, if he wants another arranger...
