Guide TE421 Compact Thermal MonocularThe Guide TE421 packs a 400 300 12 m thermal sensor with 25 mK NETD into a 295 gram pocket sized chassis a compact alternative to the larger TD series monoculars when you want thermal in your jacket pocket rather than your pack. At $999 it brings 12 m pixel pitch into the sub $1,000 tier where most competitors still use 17 m sensors, with a 25 mm F1. 0 lens and wide 11 8. 2 field of view sized for close to mid range scanning. Key Features 400 300 @ 12

The Guide TE421 packs a 400 × 300 12 μm thermal sensor with 25 mK NETD into a 295-gram pocket-sized chassis — a compact alternative to the larger TD-series monoculars when you want thermal in your jacket pocket rather than your pack. At $999 it brings 12 μm pixel pitch into the sub-$1,000 tier where most competitors still use 17 μm sensors, with a 25 mm F1.0 lens and wide 11° × 8.2° field of view sized for close-to-mid-range scanning.


Key Features
  • 400 × 300 @ 12 μm sensor with 25 mK NETD — finer pixel pitch than 17 μm budget thermal scanners
  • 25 mm F1.0 germanium lens with 1.9x – 7.6x magnification — wide native FOV (11° × 8.2°) for fast acquisition; 4× digital zoom to extend reach
  • 1,300 m / 1,400 yd man-target detection — longer than typical 25 mm thermal monoculars at this price
  • 0.32" 800 × 600 AMOLED display, 25 mm eye relief — the longer eye relief is unusual at this tier and helps with eyeglasses
  • Compact 295 g / 11.11 oz body, 47 × 47 × 155 mm — pocketable; doesn't need a dedicated pack space
  • WiFi (2.4G + 5G), Bluetooth, 16 GB recording with audio — TargetIR app pairs for media transfer and ballistic profiles
  • IP67 weather sealing — rain, dew, dust
  • Seven image palettes — White Hot, Black Hot, Red Hot, Green Hot, Iron Red, Blue Hot, Sepia
  • Built-in battery, ~6-hour runtime — quick-charge USB-C support; covers a typical morning or evening sit
  • ±5 diopter adjustment — per-eye prescription compensation

Ideal For
  • Stand and tree-stand hunters who want pocketable thermal — pulls out of a pocket faster than reaching back for a binocular harness
  • Close-range predator and varmint hunters working under 200 yards — the wide 11° FOV beats a 35 mm scope's narrower view at typical hunting distances
  • Hikers, backpackers, and law-enforcement scanners — light enough for all-day carry without notice
  • First-time thermal buyers wanting to dip in under $1,000 — the 12 μm pitch and TargetIR app capabilities approach the experience of $1,500+ tier without the price

Accessories & Compatibility
  • Ships with lens cover, eye mask, wrist strap, quick charging adapter, USB-C cable, quick use guide, safety information manual, and warranty card
  • TargetIR app pairing for photo/video transfer
  • 10-year manufacturer warranty backed by Guide's US-based repair center in Texas

Difficult to destroy. Bounce really high.
Style: Squeaker, Size: Small (2 Pack)
Bought as a gift for a friend's small dog who dismantles tennis balls. He loves them. I have many years of experience with the product (in a larger size) for my big dog. He always had one either in his mouth or near him. They are pretty much indestructible.

High quality, wish it was just a little smaller
Style: Squeaker, Size: Small (2 Pack)
Love these. My dogs would play ball all day if I let them. These are very durable and bouncy. Love that it’s washable. They would chew up the small “tennis” balls to pieces so I love that they can’t destroy these. My only criticism is I wish these were just a little smaller (like the size of the small Kong tennis balls). My dogs can carry it in their tiny mouths but they can’t get their mouth around it enough to chew it to get the squeaker to squeak, which is their favorite thing.

The perfect ball for a small to medium dog.
Style: Ultra, Size: Small (2 Pack)
My dog's favorite ball. Perfect size for playing catch and return for a small dog. She loves to chew on the ball. Very durable she has not been able to shred the ball. A great entertainment value. This ball does not squeak.
