GAM 220 MF 4-in-1 Digital Angle Finder, Includes Leg Extension, 4 AA Batteries, & Carrying Case

Use this for stairs at my work. AWESOME!

Used this tool on a handrail project and it was extremely helpful figuring out tricky angles and mitre joints. Also got complements from other tradesmen on the jobsite on how cool it looks. Perfect accuracy. And also super sturdy and high quality. I can't recommend this tool enough!

This is an excellent tool, and if you work with angles and degrees a lot this can really help you out. I do metal fabrication work for a living and use this for measuring staircases and getting accurate angles. The older version does not have the locking knob on the front like the new one does. Excellent feature. Works well and does not move position.

This makes my DYI work around the house so much easier and it takes the guess work out of angles

Overall really good. Provides accurate readings and I find the built-in level to be very handy. There are only a few things I wish was different: 1. It would be great to have a second 90 deg. level 2. A bit heavy so hard to maneuver around especially with one hand if you’re trying to draw a line or something. 3. A constant humming noise coming out of the digital unit when turned on. 4. Hard to draw accurate corners given the round end of the unit. So for instance if you’d like to draw a line with a certain angle that meets another line at a specific point this might not be the right tool. It could’ve been though if there was a built-in laser projector. Wouldn’t that be great?

This product is great well-made and well thought out. The cost seems a little high, but it is quality and will last for a long long time. This is something that you only buy once and get to hand it down to your kid if you have one.

Very solid and accurate. The miter calculator works great

Been useing these for sometime so I wanted one for my own. Can't go wrong with Bosch in my opinion.

La robustez con la que se siente es muy cómodo material de buena calidad fácil de usar y muy practico

Arrived 4 or 5 days late and was disappointed that the product appeared to be a demo, or possibly a returned, product. A few slight scratches and the manual was wasn't in the original packaging. It was loose at the bottom of the shipping box. Brad at Sitech was quick to reply to my concerns, apologized for the inconvenience, and offered to organize a return as soon as he could figure out a method of paperwork through USPS. That was two weeks ago. Haven't pushed too hard, but It'd be nice if there was some compensation. Further dismayed that a local tool supplier (Summit) had the exact same model on an unadvertised sale for $199 (CDN) when I was in their store last week. Oh well, that's on me for not calling them. As far as the Bosch 220mf, I used it once for a baseboard/crown molding job in a hallway with 14 various inside/outside corners. Took about 5 minutes to get all 28 angles for both crown and baseboard. Another nice feature is the angles on the LCD display are large enough that they can be read with ease. In the unlocked position, the protractor hinge has just the right resistance to be manipulated smoothly and will keep its place when withdrawn from a measurement. You can also easily lock the hinge with a quarter turn if desired. Moving forward, I have approximately 45-50 more corners to measure along with 3 flights of stairs and this product makes the task quick and accurate. Before I started my project, I needed some better gear to work with and the Bosch GAM 220MF is a terrific addition. Along with the GAM 220 MF, I also upgraded my miter saw to a Dewalt DWS780 double bevel slider with XPS and got a Bosch GLM 35 laser measure. The Dewalt LED XPS is awesome! I would highly recommend the GAM 220 MF.

For steel stair and railing, it's a great relief to have an accurate tool like this. I guard it jealously and treat it carefully.

Great product. Only negative comment is that they cannot be calibrated.

Design and accuracy. Bosch builds the very best!
