ALVIN drawing compasses span a massive range of sizes, applications, and uses. Our traditional beginner and intermediate level compasses are sure to find themselves right at home in any geometry or art class. Our professional-level compasses are the perfect precision tool that any engineer, draftsman, or professor needs to add to their collection of drawing instruments. These metal drafting compasses can make precision circles from 1/8" up to 22" in diameter with added beam bar.

ALVIN compasses are made with German precision engineering that allows for the precise and consistent drawing of radii. Made from quality materials such as zinc alloy, ALVIN drafting compasses are sure to last the test of time. The more advanced models, such as the 205V and the 975K, have adjustable knee joints for rapid adjustment and even greater ability to draft with accuracy. Kits with pencil adaptors allow for the attachment of a drafting pencil, pen, or marker. Add one of ALVIN's model 958 spring blade pencils to your kit with a pencil adaptor, or buy the model 505V kit to take your drafting abilities to another level. This pen is finely honed to create precise lines with India Ink.

this is a nice compass, works well and keeps the setting. only bad thing is the screws for the interchangeable leg come out easily and can get lost. would be better if the screw would only loosen but not be removable. otherwise it works well for my needs

The quality of this product is wonderful, for what the price is... you just need to get the hang of using it, cause it is awkward at first... had to make circles for my design class and I got tired of it, so I free handed them... and she couldn't tell the difference... however, it does what it needs to and more... the extra tip where you apply more medium... is a wonderful thing... I like it just for that cause it creates a crisp clean line I never could.

First let me start by saying the seller was awesome and I got my compass set quickly and without any issues. Sadly, this compass set was a disappointment, especially when compared to an older 1980's Alvin compass. The smaller compass handle broke off the first time I used it and the larger compass legs won't stay locked and bow/flex at the worst possible times.

I use this for small woodworking projects and plans, it is compact and seems like very nice quality.

The compass and divider are probably great, but I wouldn't know since Amazon sent me a used and broken product. Not only was the kit clearly used, but it was missing pieces and came with a broken case since it was shipped without any wrapping or padding.
