Choosing between a standalone metal detector and a metal detector plus checkweigher is really a question of how much verification your line needs in one pass. For product inspection checkweighing, the ADS ProScan Max II Digital Metal Detector Washdown Conveyor System comes in at $4,499.99, while the Mettler Toledo Safeline Metal Detector & Checkweigher Combo Conveyor System is listed at $15,000.00. The ADS unit concentrates on contamination detection for food production; the Mettler Toledo combo adds inline weight checking and reject handling. Both are listed as used units from the United States, so the practical difference is what each machine is built to do.
Quick verdict
Choose the ADS ProScan Max II if you want a lower listed price and a focused food-production metal detector. Choose the Mettler Toledo Safeline Combo if your line needs to catch contamination and reject off-weight packages in the same station.

Where each product wins
The ADS ProScan Max II is set up for a dedicated metal detection job. It is described as waterproof, includes three test samples, and supports auto-learn with different settings for pre-programmed items. That fits a food-production washdown line where the main check is contamination.
The Mettler Toledo Safeline Combo wins when you need both checks at once. The listed system combines a metal detector with a checkweigher, has touchscreen HMI controls and dual push-bar reject stations, and uses stainless steel construction. It is described as previously used for 6 oz and 15 oz containers, so it aligns with packaged-weight applications.
Product notes
ADS ProScan Max II Digital METAL DETECTOR Washdown Conveyor System Food Service
This is the lower-priced path in the matchup, and its listed feature set is aimed at food production. The washdown conveyor metal detector is described as waterproof, comes with a set of three test samples, and has an auto-learn feature that can apply different settings to different pre-programmed items. The listed opening is 12 inches wide by 3-3/4 inches tall, which points toward thin or low-profile packages. It runs on 115V with two standard plugs. The trade-off is the metal-detection focus; if weight verification is on your checklist, the combo system covers that part of the job.
Mettler Toledo Safeline Metal Detector & Checkweigher Combo Conveyor System
This unit, listed by merchant EJei2--Tgi, combines the two inspections into one inline station. It is described as a stainless steel construction system with dual push-bar reject stations, including metal-detect reject and light/heavy reject, which makes it useful for lines that need to confirm both contamination and package weight. The listed effective aperture is 10.5 inches high by 7.75 inches wide with a 2.5-inch conveyor width, and the description says it was previously used for 6 oz and 15 oz containers. The main limitation to plan around is the electrical side: it is listed at 480V 3-phase.
Final choice by use case
Choose the ADS ProScan Max II when your primary job is metal detection in a food-service washdown line and you want the lower listed price. Choose the Mettler Toledo Safeline Combo when you need one station to handle both metal detection and weight verification, with dual push-bar rejects for metal-contaminated and off-weight product.
