the best ones have the moving distance, you don't have to click every time to get a distance. that price is fine, but look a little lower at homey depot or lowes for another model. i have never used the model in the picture, but the word 'professional' means mo money. i use the professional glm 20. bosch has the best red dot, but none of them can be seen in very bright daylight, that's why the moving distance can make sure you got it right. this model looks thinner than the 20, that's a plus. i gonna look at this one too.
If I was a women I would keep it and carry it in my purse and pretend its a Taser Gun and carry it as a weapon. When I was a young man some guy pulled a knife on me and said give me your wallet. I carry my Disto on my belt on the right side. I size him up and decide I am going to take him down. I get eye contact and slowly place my right hand on the Disto. I then slowly slip it into my hand and tell him that I have a (9 MM on my belt and to drop the knife or I am going to make your day. He looks and I pull the Disto out and point it straight at his heart and he has a black hoodey on. I smile and I say to him see that Little Red Dot on your chest ? Thats where the first bullet is going-to hit and the second one will be in your head. The clown actually looks down and sees the Red-Dot and he throws the knife and runs. Its also a great toy play with cats. My two Toms, love to chase that little Red-Dot on the carpet and walls- 1995 The Day My Disto Saved My Life : )
just looked at it. the glm 20 model is about $100 less. but i do like the brighter, larger numbers on the screen. the only aggravating part is always finding the red dot in bright sunlight. they are good for indoor measuring. i will pay more to have less aggravation, even 5 seconds less. i also like that it is thinner than the 20 model. i think i am talking myself into getting it. doesn't hurt to have a spare.
