Product notes
Honeywell 1991ISR-3-N (lot of 2)

With the Honeywell 1991ISR-3-N, the purchase is designed around coverage. The lot of two means you can keep one scanner on a receiving line and another at a packing station, or hold one as a backup. It is positioned as an ultra rugged industrial 1D barcode scanner, which fits plant-floor and warehouse environments. The price is USD 210.00 for the pair, working out to USD 105.00 per scanner. That is the clearest reason to choose it: if you need two devices, this is a way to get them in one purchase. The limitation is the higher total spend. You pay more upfront than you would for a single Datalogic, so if you only need one active scanner, the two-pack is more than your workflow requires.
Datalogic POWERSCAN PM9501

The Datalogic POWERSCAN PM9501 takes the opposite approach: one scanner at a notably lower price of USD 59.98. It is positioned for both retail POS and industrial scanning, so it suits checkout counters and industrial scanning tasks. The package includes the OEM battery, a useful convenience because you can scan right away or swap in a fresh battery when the first one runs low. That battery inclusion plus the lower total price is the main reason to go this route. The limitation is that you get a single unit, so simultaneous scanning at multiple stations means another purchase. The unit is seller refurbished, which matches the condition of the Honeywell, so the choice should come down to coverage and spend.
Final choice by use case
Choose the Honeywell 1991ISR-3-N lot of two when your machine vision identification workflow needs a spare scanner ready to go. Choose the Datalogic POWERSCAN PM9501 when you want the lighter buy-in and the included battery gets you scanning right away. In short, the Honeywell lot trades higher total spend for coverage; the Datalogic keeps the initial outlay smaller.
