Viper Laser Throw Line Markers – Battery-Operated Precision Oche Lights in Multiple Styles

Works perfectly on the dartboard cabinet I made, In combo with the viper shadow buster light ,my game is more enjoyable to play. Mounted easily to underside of cabinet with 2 screws. A tip onadjusting the line: as you tighten the 2 screws next to the laser, the throw line will slowly creeptowards the dartboard face. So set the laser line back a couple inches and slowly tighten the twoscrews equally til the line matches your 93 1/4" mark.

Why did you pick this product vs others?:Was a little hesitant due to a few reviews overall quality is solid multiple of rounds, easy install and have left on for several nights and battery draw is minimal good for what it is.

The girl didn’t like the idea of an oche line in the middle of her floor, so I took a gamble on this. Very tricky to get both the pitch and distance dialed in, then have tightened down without the line moving. It will try your patience! Once you get it set though, it works really well. Very bright. Mounted mine a little lower (3 1/2’) than what’s pictured and it gave me about a 2 1/2’ long line. Laser is strong enough I imagine to be mounted anywhere and be good. Though the base and laser head seem solid, I worry anything more than a mild bump will knock the line out of place. All in all, great value for the money that solves a problem.

Great product, laser projects on the floor and is much cooler than tape on the floor. Getting it positioned correctly and having it tightened is tricky because it wants to move when tightening, but once you finally get it locked in at the right spot it does stay. Great product and excellent price!

The only room in my home suitable for a steel tip dart board installation was the bonus room. This room has carpet on the floor, which is great to hide any marks left by darts that fall to the floor, but make installing a toe line more difficult. The Viper by GLD Products 37-0108 Laser Throw/Toe Line Marker looked like the best solution that I could find so I picked one up on Amazon. It has worked great. I didn't buy the power adapter and opted just to use batteries, but one is available for purchase. It is mounted close to the floor (bottom of the board in the photo provided) to ensure no one, especially my kids, would have an opportunity to look into the emitted laser.It was very easy to install with just two philips screws (included) that mounted directly to the back-board for my application. I ran a tape measure from the wall to the throw line distance of 7' 9.25" and then lined up the laser to that position on the floor. The battery compartments are on the front of the device, so the batteries can be replaced without moving the device.The only downside is that it doesn't have an auto-off feature, so if accidentally left powered on it would drain the batteries.

I've got zero complaints about this toe line laser. Bought it three years ago and it's been a tough little guy under the shop dart board ever since. In the picture you can see the laser on the wall just below the board. By the peppering all over the wall & board you know 2 facts; 1) This thing has taken multiple and impressive hits. 2) Drinking and playing "trick shot HORSE darts" is not recommended for those that treasure their walls.That all said, it continues to work just fine despite getting hit more times than Tina after Ike came home off a weekend of binge drinking and 8-balls. Not only does it work fine, but the thing stays exactly where you set it. Unless, of course you hit it. And just like Tina, it will move if you hit it so....don't do that.Fantastic product. If/when it ever dies I will absolutely purchase again.

Works great, easy set-up, fast shipping.

This works and so I considered giving 4 stars but the setup was a bit frustrating and ridiculous.It mounted easily enough and it was lightweight enough to mount to my hollow wooden door without anchors. Due to the rotating nature of the laser you also didn't need it to be perfectly level to get the laser to be straight which is nice.My issue comes with setting up the laser to the precise line. The first time I set up the laser I had taken a few minutes to line it up and then I screwed down the screws to keep the laser positioned correctly. Seemed easy enough until I realized that screwing it down moved the laser up by a foot.If you line it up first then screwing it down will move the line. You can try to pinch the laser while you tighten the screw it will still move just a bit. If you tighten beforehand and try to adjust after, making the micro-adjustments necessary for precise alignment is a pain.Keep in mind that I did this by myself which makes it more difficult but my advice to people doing it on their own is measure out and then put an large book right behind the line. Then tighten down enough where the laser won't shake out of place but loose enough that you can make subtle changes to line up the laser precisely. The book will be a better reference point then just a tape measure on the ground but the hard part is finding the tension balance you need to line it up smoothly. It isn't impossible of course, just more of a pain than it should be.I would really like to see a type of scroll wheel you could use to make micro-adjustments after tightening the tension screws.So far it works well and although I have read some reviews saying that it is difficult to see in sunlight, I have found that it is manageable in all but the most sunny outdoor situations. I did put a fresh pair of eneloop batteries in so it's possible that even batteries with less charge would result in a duller less vibrant laser. Also regarding the batteries I have only used it for a few hours but will update the review once I have a better judgment on battery life.The laser is cool once it is setup but I think it is mostly unnecessary. It works well enough but I caution people when picking up bounce outs not to get a laser in the eye. Considering it seems of decent quality, isn't too expensive, and works I can recommend it if you really want a laser oche instead of using a adhesive tape line.Pictures description:The half carpet half hardwood picture shows the laser in good indoor CLT lighting.The marble picture is a close beam in good indoor fluorescent lighting on a light surface.The all hardwood picture shows the beam in a direct afternoon sunlight.
