## Description

Mars drafting head for use with A3 and A4 drawing boards. Suitable angle range: 0-90°. Stop-and-go push-button for easy setting at desired angle and freewheeling. Transparent ruler arms with double-sided opposite-running scales. Can be used with one hand.

Review: Il tecnigrafo corrisponde esattamente alla descrizione che viene fatta, ottimo anche dal punto di vista della precisione e della stabilità senza tener conto della robustezza dei materiali di cui è fatto. Rapporto qualità prezzo eccellente.
Review: Along with the board, this item is top quality, easy to use even for a 12 years old boy passionate about technical drawings. The price is a little bit high, in my opinion, a fair price is about 25 Euro but I am not a professional, I am just the guy that owned and used the credit card :)) Nevertheless that doesn't mean that needs stars down, because functionality is everything. Locking mechanism on the ruler is very smart and thin. Also the locking mechanism on the rotating mechanism is very smooth. It has some kind of window magnifier, which makes the reading on the ruler faster I think. From what I understood it contains 2 special positions for "isometric" view, hope the term is correct. These positions and overall position are 100% repeatable so that is the hole point! I hope in time will have the same precision. Anyway my son is happy, so 5 stars also for this item!

*by P***G on 30 November 2024*

Buen accesorio combinado con el tablero de dibujo. Ha sido una grata sorpresa descubrir que viene con posiciones prefijadas con ángulos de 15, 30,60 y 45 grados que se enclavan automáticamente, lo que agiliza mucho trazarlos. Tiene marcados los ángulos de 7 y 42 para dibujos en un tipo de perspectiva bastante habitual. Se puede hacer con escuadra y cartabón? Por supuesto, pero para medir ángulos desconocidos o trazar ángulos y sus complementarios rápidamente viene de perlas. El ajuste es muy bueno, no se mueve fácilmente por lo que dificulta que arrastremos errores acumulados en diseños complejos. Puede parecerme algo caro, pero es cierto que es de calidad, Buenos materiales y ajuste, artículos similares me han parecido más endebles.
