CATIGA Graphing Scientific Calculator — Graphing & Scientific Combo
Product description
Combines scientific and graphing capabilities in a single handheld unit — plot curves, inspect graphs, and work with the matching equation displayed simultaneously. Designed for a range of classes from algebra and trigonometry to calculus and statistics.
An economical midpoint between a basic scientific calculator and large, costly graphing models. It covers plotting, solving equations, and many advanced operations so students can step up to graphing without a steep investment.
Provides more than 360 functions and three flexible modes for angles, calculations, and display formats. Functions include fraction handling, complex numbers, statistical calculations, linear regression, standard deviation, and variable solving — sufficient for early math through advanced coursework.
Built for portability: a compact 7 x 3.3" chassis that fits in a hand, on a desk, or in a backpack. The housing is designed to resist drops and comes with a protective slide-on cover to shield keys and the screen while traveling. The unit weighs about 6.4 ounces for comfortable all-day carry.
Includes a 365-day limited warranty and customer support response within 24 hours. A small reset button on the back can revive the unit if it will not power up.
Pros

VerdictA capable, budget-friendly graphing scientific calculator aimed at high school and college students. It combines graphing and scientific features in a small package with hundreds of functions and adaptable modes. Good for algebra through calculus, though occasional build and usability quirks were reported.

Easy upgrade
A good upgrade — my old calculator was three decades old.

Pleasantly simple
Nice calculator!

Read the manual for quirks
The exponential (e) entry behaves differently than some other scientific models, so consult the manual. Occasionally a key press needs a second tap. It does allow entering operations in natural order, just remember parentheses for correct results.

Michael Kilinski 3/5
Functional but average build
Overall it works. The cover is oversized and slips off, so it doesn’t protect the unit well in a bag. Buttons can feel loose and rattle. Instructions are brief and require experimentation, but the calculator completes the needed tasks.

Handy for schoolwork
Very handy — exactly what my daughter needed.

T. Linz 4/5
Does the job; a bit flimsy
It gives correct answers and the keys are legible. The body feels fragile and might break under heavy pressure. The included batteries arrived depleted, so I replaced them — a minor annoyance.

Excellent and intuitive
Excellent calculator, practical and intuitive.

Gareth Greenwood 3/5
Not as powerful as high-end programmables
Fun for nostalgia but limited compared with premium programmable models. It’s probably the most affordable option with some programmability, but serious users will prefer top-tier brands.

Graphing is unclear
Labeled as a graphing unit, but I couldn’t find how to produce graphs. Several teachers tried and we still couldn’t figure it out.
