prisma phassed array

Prisma is single group only - For multigroup you need the veo or veo+, I'd recommend the veo+ a significant performance improvement over the older version.

Also with Prisma make sure it has the options you need installed - It may not be cost effective to upgrade a second-hand set - Fully loaded the options are as much as the base price (or used to be).

The Prisma is a very good unit for the right applications, I still do a lot of training with it and recommend it highly, but it can 'run out of steam' if you need high speed or complex inspections performed.
