Description & Tech Specs
Smart, fast, and safe! The LineScale 3i design was influenced by HowNOT2 and crowdfunded with the HowNOT2 audience.
SMART: It records 100 logs internally and we have created the easiest graphing software to use... just drag and drop at the bottom of this product page
FAST: It reads up to 1280 hz which is super fast enough for most drop tests. See how many hz you need for that in this VIDEO
SAFE: It is PPE and UIAA rated at 25 kN (10 kN recommended), WLL of 30 kN, MBS at 90 kN, and in our test, the body broke at 140 kN
See how it compares to the Rock Excotica Enforcer and watch us break test it in our video here

All models are now the LineScale 3i!
The "i" stands for "improved".
Improved, as in revised and thus better than the predecessor in terms of torsion resistance, and temperature stability.
The LS3i features a few minor refinements, such as:
- solid reverse side (no more inserted plate)
- slightly larger front label (but same OLED)
- less torsion and bending sensitivity
- less temperature sensitivity (almost perfect temp. compensation)
- 10kN higher true breaking strength (15 instead of 14 tons MBS)
- better IP rating (IP68-0.1m instead of IP67)
(the specs, electronics, OLED display, etc. remain the same)
EVERY LINESCALE INCLUDES: LineScale3, hard plastic protective case, charging cable, and firmware flash adapter.
FULLY EQUIPPED INCLUDES: everything in the base unit PLUS the 4 GB dual USB, rubber edge protector, and angled OTG cable.
