A TE system are only dependent of the TE-probe and non-leaking tubes.
A electronical system are dependent on correct dynamic- & static probes, the relative position of the two and non-leaking tubes. i.e a system which more factors to consider during installation.

I have chosen TE based on these factors:
- TE was fine with my previous computer (Zander)
- Static ports are known to have problems on old gliders (read any of the Johnson reports)
- My glider has dynamic in the nose and static on the tail boom, which is not good enough for electronic compensation.

I think that electrical compensation is only valid if you have an multi-probe in the fin. For the rest of us in the TE-compensation better.

Read Borgets guide for installation. All modern computers are of pressure transducer type, therefore is there generally no problem to have a mechanical and electrical vario on the same TE-probe if you follows the guidelines below.
