Hi Charles,

Please see diagram below.  you measure to the bottom of the unit but you need to make sure that you have it as SLANT on the logger if you are using Topsurv.  Hope this helps.

I have a question, not being Topcon Savy when using a Hiper Plus unit do you measure your HI from the yellow arrow or from the base of the reciever?
