Bighorn 6-Inch Digital Angle Slope vs Klein Tools 935DAA Digital Level

The Klein Tools 935DAA is the better-built tool: IP54 sealing, a 6.6 ft drop rating, rare-earth magnets and the Angle Alert LEDs and buzzer that tell you when you hit your target angle without watching the screen. The Bighorn is a 6-inch digital level with a spirit bubble, a backlit LCD and four measurement units, so it doubles as a short level. Reviewers of digital angle gauges consistently favor the Klein for jobsite durability and repeatable angle setting; the Bighorn suits light shop and hobby work.

  • Choose the Bighorn if you want a short digital level with a spirit bubble, a backlit screen and readings in degrees, percent, mm/m and in/ft.
  • Choose the Klein Tools 935DAA if you set angles on conduit, pipe or saws and want drop protection, dust and water resistance and an audible angle alert.

What reviewers say

Klein Tools 935DAA Digital Level

Owners and reviewers treat it as a handy pocket tool for conduit and angle work, with the Angle Alert and magnet called out as the reasons to pick it over a plain digital gauge. Complaints center on its small size and the buzzer.

What people mention
  • Angle AlertPraisedUsers say the LEDs and buzzer let them hit a target angle without staring at the screen.
  • MagnetPraisedThe rare-earth base grips conduit and steel well enough to free a hand.
  • SizeMixedPocketable, but too short to check long runs like a full level.
  • DisplayPraisedThe reverse-contrast screen stays readable in bright light.

Questions and answers

Which is better for bending conduit?
The Klein 935DAA. Its rare-earth magnets grip conduit, and the Angle Alert LEDs and buzzer confirm the bend angle without you looking at the screen.
Which is more accurate?
The Bighorn publishes its figures: 0.05° resolution and ±0.1° at 0° and 90°. Klein does not publish accuracy for the 935DAA, so the Bighorn is the safer claim on paper.
Which lasts longer on a jobsite?
The Klein. It is IP54 rated against water and dust and rated for 6.6 ft drops. The Bighorn publishes no drop or ingress rating.
Do I need a spirit bubble?
Only if you also want to check level the traditional way. The Bighorn has vertical and horizontal bubbles; the Klein relies on its digital level function.
Is the Klein worth stepping up to?
Yes if you work outdoors or on steel and want hands-free angle confirmation. The Bighorn is enough for bench and hobby work where the tool stays clean.
