Hi Mark,
For clarity sake, I'll start by letting you know that I do in fact work for Fortress Technology metal detectors. So, of course i do recommend our brand and yes, I know this post will be perceived as biased. We have built our brand on keeping the end user needs in mind by building equipment that is extremely reliable, simple to operate and provide we excellent support.
Furthermore, the best unbiased advice that I can give you is; Whichever brand you decide to go with, just make sure it is a reputable brand that you will be able to easily get support/parts for (including annual or more frequent certification), now and into the foreseeable future. Without good support you may be dead in the water if you run into issues. Especially true if this is a CCP.
Regards,
Eric
