Ian,
as George pointed out, you need both. But there is one good thing: you don´t need to learn them if you don´t want. Just make sure the camera is set up correctly in Maxim, and Sequence will control everything. You don´t see PinPoint even running, it just has to be there. After the pointing model or MLPT is done, you might continue as before.
Nevertheless, once you have Maxim you might consider to use it for the whole acquisition Task, but this requires some learning.
Both programs arer available as 30 days Trial.
