I have a Csx and it is a dandy little instrument. I bought it at PCNation for a good, good price...about $240 at the time.

Of all the bells and whistles it has, I use the electric compass the LEAST. As sophisticated as it is, the compass will not allow you to shoot an azmuth in order to triangulate a boat on open water (using two azimuths from two known points. Why is that important to me? Well, let's just say that if I see folks parked over open water and boating a bunch of good fish, I get a bit curious and want to know e x a c t l y where they are sitting.

Shooting an azimuth would be the easiest way, but I have adapted and have found other ways. lol

The 76 will do you just fine, but it does not have the memory capacity of the more sophisticated ones.
