Choosing a barcode scanner for machine vision identification often comes down to balancing upfront cost, hardware condition, and the types of codes you actually scan. Right now the decision is unusually sharp: one option is a Honeywell 1991ISR-3-N ultra rugged industrial 1D barcode scanner sold as a lot of two. The other is a new Tera Industrial 1D/2D wireless barcode scanner model D5100. The price spread between them is roughly $190, which makes you pause and think carefully about your workspace layout and scanning needs.
Quick verdict
If you need two independent scanning stations and can accept seller-refurbished hardware, the Honeywell lot gets you a spare right away. If you need a new scanner that reads both 1D and 2D codes and want Bluetooth connectivity for less money, the Tera D5100 is the practical pick.
Side-by-side comparison
| Feature | Honeywell 1991ISR-3-N (Lot of 2) | Tera D5100 |

| Listed price | $210.00 | $19.99 |
| Condition | Seller refurbished | New |
| Wireless connectivity | Wireless | Bluetooth |
| Barcode types | 1D | 1D/2D |
Where the Honeywell lot wins
The biggest practical advantage is that you're getting two scanners in one purchase. If you have two stations or need a backup unit, that alone can justify the higher price. The "ultra rugged" wording in the title signals a design aimed at demanding environments, and it's a 1D scanner, so for basic barcode counting it should handle the job.
Where the Tera wins
The Tera D5100 wins on new condition, 2D capability, and lower price. You get a brand-new scanner that reads both 1D and 2D barcodes - important if you're scanning QR-style codes or newer label formats. Bluetooth connectivity is part of the package, and the orange and black color makes it easy to spot.
Product notes
Honeywell 1991ISR-3-N (Lot of 2)
The Honeywell 1991ISR-3-N is sold as a lot of two, and at $210.00 it's the higher-priced option. The main reason to choose this is the two-unit format: if you have a busy area where one scanner is always being passed around, having a backup unit on hand is a genuine workflow advantage. The title also calls out "ultra rugged," so it's aimed at industrial handling. The limitation is that these are seller-refurbished units rather than new, and the model is a 1D scanner only. If your labels include 2D barcodes, this won't read them. It does connect wirelessly, which keeps the work area tidy.
Tera Industrial 1D/2D Wireless Barcode Scanner Model D5100
The Tera D5100 is the new option at $19.99, and it reads both 1D and 2D barcodes, which gives you more flexibility if your labels include QR-style codes. It connects over Bluetooth and includes USB support in the model name. The orange and black finish is distinct and easy to recognize. Because it's new, you don't have to think about prior wear. The main limitation is that the price covers a single scanner; if you're equipping a team, you'll need to buy one per person. That still gives you a low cost of entry, but the total outlay grows as you add units.
Final choice by use case
Choose the Honeywell lot if you run a receiving area with two staff members, you're comfortable with seller-refurbished equipment, and your codes are all 1D. Choose the Tera D5100 if you want a new scanner, need 2D capability, and prefer to spend the lower amount - or if you want to keep one scanner at each of several desks without a large investment.
