Difference between ....

[11chaos]

Does anybody know the difference between the Construction Master IV and the Construction Master V? I would like to know if there is a reason I would need to buy the V. thanks

Oh yeah, these are calculators.

Don't quote me - but I think the major difference is the integrated case on the V.. but think you can get something similar for the IV. I've got the construction master Pro with an armadilla gear case.

Yeah, i've seen the case for the IV. I will continue to use my Const. Master IV and the calculators here. I am just glad to see the price going down. I remember buying my first one for $80 or so dollars. Now you can get one around $40.
