Review on Rack Tiers 52300 Studball Colors by Derek Jha

By far the best spike finder I have ever used for finding the centers of metal spikes. I've used many other neodymium magnets and any of them are good for finding the bar, but they're not accurate enough for finding the center and unprotected magnets leave marks on the walls. The spherical shape of this magnet allows you to move the magnet around to see where it sticks best and place it right in the middle. The magnet is strong enough to stick to a steel rod through 5/8" thick drywall. It will stick even stronger to the screw/nail heads, which can also help with finding the center, but the screws aren't necessarily in the Center, so I try not to rely on the location of the screws when drilling a large hole for a lever bolt.I do a lot of plumbing work that requires drilling a 1/2" hole to insert a wide metal bolt , which leaves very little room for error. Since I've had my spike, I've never failed to find the center of the spike on the first try. And the rubber case leaves no marks on the wall. Yes, it's a bit overpriced and I wish they were cheaper but it's worth it. I've already bought a second one and if I lose I'll buy more. They're great for wooden or metal spikes. T9) It's a good idea to start with the S finding peak, it speeds up the process, and then I use the peak to confirm and find the middle. If you just need to find cleats occasionally and aren't a pro, then a cleated ball alone is all you need. Conclusion: buy it, you won't regret it. (Only downside - I still haven't found a good way to store it so it doesn't stick to other metal objects or my other magnets. But that goes for most neodymium pin finders. I could end up making some sort of protective styrofoam case, I wish , there would be something included or would have a protective cover as an accessory)
