Question: Will it work at a 45-90 degree angle at 50 feet?
Document: I read many of the reviews and didn't know what to expect at first. After using it according to the directions (yes, you still have to read them after all these years), I found that this product is good for Little League and Pony League baseball (46 to 52 feet), but you have to be close enough to the pitcher for it to work well (within 75 feet), and be directly in line with the pitch to limit the angle and get a more accurate reading.
Had seen this product in use so bought one for little league use. It works pretty good if you have the right angle. Best used from a scorekeeper's box with angle directly behind catcher shooting out toward pitcher. Or just to the left or right of catcher. If your angle of shooting is more than this it will not read correctly. This product will help players work on their pitching form by giving them feedback as to what changes are producing speed.
Works ok, got to make sure you're behind the pitcher no more than 5-10 feet for accurate results.
It won't pick up the speed of the baseball from ten feet behind the plate. Waste of money especially 85 dollars
Accurate? Yes, but it takes time to get the right speed reading. Also, range is pretty poor in my experience. It's about 250 feet. I like how it runs on K band though.
This is an excellent item. I wanted to see how accurate it was and set the cruise control to 55mph then had my passenger point it at the ground. Sure enough it was on the money. I changed speeds several times and it worked flawlessly. I have gauged over 500 AAA pitches. The U11 team pitchers tend to pitch between 40 to 49 MPH. There are several that can hit 50 mph and about 4 kids who can throw over 50, top speed 55mph strikes.
Appears to accurately measure velocity of baseballs, softballs, even wiffle balls. It helped me teach my kids that 50 mph vehicle + 50 mph vehicle = 100 mph impact. This radar gun is accurate only when the object being measured is on a direct collision course with the gun, but that's what I expected. So don't sit on the third base line at a baseball game and complain that your son's pitches are being clocked too slowly. Go back to physics class and recall vectors.
I bought this gun and am not able to use it at any games. I am not able to pick up any readings, even sitting directly behind the backstop. I have tried about 15 different parks traveling with my team. This has been a horrible experiment. If your sitting more than 8-10 feet behind catcher,as at most parks, this gun is useless. Don't make the same mistake.
The product description states the speed gun measures "Auto racing range: 6 to 200 mph (1,500 feet away)." On the package the speed range is clearly defined as 10-200 MPH. I purchased this product to help enforce safe speed limits on our job site. Because the product doesn't begin measuring speed until 10 MPH, it is useless on our 5 MPH site.
Got it for my 9u travel team. It works well. Great price. Gives me a gauge on different pitchers and their pitches. Easy to operate. I find it accurate enough for this age application. Kids are throwing in the 45-55 mph range.
Answer: I don't think so.  The most I've tried is 30 degrees and it works at that angle.  The instructions say it won't work at 45 degrees but I haven't tried.
