Developed in the UK and distributed worldwide, the Prey range of equipment created by Detech Europe Limited is a continually developing and improving windows 10 based software interface combined with a quality hardware platform.

Based upon Detechs many years of experience in the electronics manufacturing sector, the Prey range is designed to offer customers what they want and need while keeping costs down and implementation simple.

The Prey AOI range offers a price competitive solution that makes full inspection capabilities accessible at almost every budget without sacrificing functionality and ease of use. Our systems have been optimised for remote support to enable us to get our customers answers fast meaning their manufacturing process can have maximum up time.


This benchtop inspection system, the Prey Merlin, offers all the capabilities of machines more than twice the cost.

Using a 5MP camera, the system gives the ability to inspect almost any component.

A robust yet flexible universal carrier system gives the user the flexibility to quickly insert a PCB up to 450mm x 350mm, clamp it and inspect with the press of a single button, once complete the PCB is returned to the load point ready for the next PCB to be loaded.


The Merlin includes full 1D and 2D barcode reading as standard to offer a fully traceable solution that can be combined with the user-friendly Prey rework suite.

The Merlin combines excellent mechanical stability with the latest in 64bit software to give one of the most truly unique inspection solutions found anywhere in today's global market.


Prey combines all its systems with our tried and tested rework and trace-ability solutions to give any user a complete picture of their manufacturing process.

The Merlin is an all new dramatically improved system for 2021 and is a constantly evolving system being tailored to our customers’ needs.

Latest updates (main improvments only):

1. New RGBW ligh􀀞ng unit provides uniform ligh􀀞ng over an increased field of view and improves detec􀀞on of shallower joints.

2. Op􀀞onal 12 Megapixel camera to allow either increased op􀀞cal resolu􀀞on or a larger field of view at the current resolu􀀞on to increase inspec􀀞on speed (available Spring 2021, will be fully retrofitable).

3. Inline Falcon system available offering complete program compa􀀞bility with Merlin benchtop.

4. So􀀡ware interface remains the same so no retraining of operators or programmers required from previous versions.

5. All systems have 3 fiducial correc􀀞on allowing for stretch, shrunk and skewed PCBs.

6. Unique Analysis bu􀀳on that allows the so􀀡ware to work with you and train component fluctua􀀞ons.

7. The Merlin is a fully CE Cer􀀞fied system offering unmatched value and reliability on a windows 10 coded software interface giving the user many years of use backed by a full engineering and software Detech development team.
