Description

Spectra Prescision HL450 Laser ReceiverThe HL450 Laser Receiver features a digital readout of elevation that provides a numeric display of 40 mm or 1. 5 inches. The readout is displayed on the large front and rear LCDs and shows exactly how far the elevation is from on grade. Accurate measurements can be made without moving the rod clamp, saving time, and increasing productivity. The patented anti strobe filter eliminates false readings from LED lights that are commonly found on the job

The HL450 Laser Receiver features a digital readout of elevation that provides a numeric display of ± 40 mm or ±1.5 inches. The readout is displayed on the large front and rear LCD’s and shows exactly how far the elevation is from on-grade. Accurate measurements can be made without moving the rod clamp, saving time, and increasing productivity.

The patented anti-strobe filter eliminates false readings from LED lights that are commonly found on the job site such as vehicle hazard warning strobe lights. And with the digital readout models which have the prefix HL, you do not even need to get the receiver to the on-grade position because it displays how far from on-grade you are - allowing you to work faster and more accurately. You can quickly estimate how much material you need to cut or fill.

  • Reliable Accuracy: All our models have different settings to suit your jobsite tolerances. The units of measure can be displayed in millimeters, centimeters, feet & inches and fractional inches.
  • Crazy Simple: The laser receivers all include a display on the front and back for easy visual indication of detector status and grade information. The display shows proportional arrows to help you find the on-grade position rapidly. An adjustable audible tone indicates high, low and level. All basic functions are a single press away. Set your accuracy and loudness levels and get to work.
  • Operating Time: Equipped with 2 AA batteries, all the models deliver long operating time to keep you working on the jobsite.
  • Reception Length: The longer the reception zone, the quicker you can acquire the laser beam allowing you to get your work done faster. When used in vertical, a longer pick up zone allows more control when doing tilt-up or curtain walling.
  • Tougher than Tough: Designed to withstand a direct drop up to 10 feet* (3 meters) onto concrete meaning less downtime due to damage and service requirements. In addition, the IP67 waterproof housing protects the unit from the harsh environment it is used in. Drop it in a puddle or get concrete on it, just wash it off with a hose. It is that good we back it up with an over-the-counter exchange policy for all warranty claims within the defined warranty period giving you peace of mind.

3.5 Stars -- Sturdy but Limited
Color: Purple, Size: Large (Pack of 1)
I got the Barnacle toy in size Large for my ~45 lb mutt. She enjoys food toys, and I wanted to find one sturdy enough that I felt safe leaving her with when I left for work since she tends to destroy her toys quickly. First thing -- there's no way any dog is going to be able to destroy this. The "rubber" is super thick and a good balance of flexible and sturdy, so she can't do her favorite "pick at a weak edge and slowly disembowel it" trick. I've had it for a couple months now and it looks brand new. However, it isn't great for feeding her kibble. She eats 1 cup at morning and at night, and none of the compartments fits that comfortably. I don't really feel like dividing her food into 3 portions every day to split it between either. The bigger problem is the hole size, or rather the ratio of kibble-to-hole size. The holes are very big with rubber "fingers" inside to slow the food spill. I've still found that it tends to dump a fistful of kibble all at once, or not let anything go for a long time. This may have to do with my dog's "technique", as described below. Another problem is that since this has three separate chambers, this toy is not hollow and is surprisingly heavy. While my dog has no problems throwing a kong around (and I mean THROWING a kong around), the weight and asymmetrical shape makes it difficult to throw or roll, which is my dog's preferred way to use a food toy. This toy works best when a dog slaps it with her paws or picks it up and drops it, which may be why my dog gets frustrated with getting her food from it. What this toy is really great for, for us, is high value treats. If I am leaving at an unusual time and anticipate that she's going to fuss, I can put "the good stuff" in this toy and then she doesn't mind the struggle at all! The different size chambers make this especially nice if I'm breaking up odd sized or home made treats and want her to stay busy for a while. Since it's so sturdy, she can chew on it all she wants, but she has to do the work to get the treats. All in all-- this toy isn't great for my dog's daily feedings, but it's great for high value treats and a change of pace.

Actually a challenge for my genius dog!
Color: Purple, Size: Large (Pack of 1)
I am pretty sure my dog owns every puzzle toy and treat-dispensing dog toy that exists, and he's able to figure most of them out in less than 5 minutes. Many last no more than 60 seconds before he's solved them. The Barncle, however, is actually a challenge for him! The Barnacle has three "compartments, " none of which are connected. All three have a rubber "mouth" that helps keep treats inside. The rubber "mouth parts" are very effective and make it quite challenging to get treats out once they've been placed inside. You can trim the rubber "mouth parts" to make it easier to let treats out, but I'm not doing that. I'm glad that it's not challenge! The Barnacle keeps my dog occupied for at least 30 minutes, which is a LONG time for my dog who usually has a "What next?" attitude towards toys. Th only "bad" thing about the Barnacle is that it's so hard to get treats out of, even for humans. Therefore, it could attract vermin if you're not careful to clean it out.

Great toy for dispensing dinner!
Color: Purple, Size: Large (Pack of 1)
This is one of my puppy's favorite toys! We always try to use toys to dispense his meals, but many of them become too easy for him. Kongs take no time at all to empty. This one seems to provide much more of a challenge, mostly due to the three different sizes of compartments and openings. He'll empty the largest compartment fairly quickly, but the small one almost always has a piece or two of kibble that he just can't get out. This helps to keep him interested in the toy throughout the day. We use a large breed dog food with larger sized kibble which helps to add to the challenge. The fact that this bounces erratically and doesn't roll smoothly makes it difficult for my dog to develop a method for emptying it quickly. With some other toys, like the Kong Wobbler, he quickly learns to just push it around with his nose. This toy makes him work much harder! The construction of this toy is very sturdy. We usually feed one meal a day in this, and it's held up well to heavy chewing. I (and my roommates) appreciate that it's made of softer plastic which doesn't make as much noise on the hardwood floors as some of his other toys. The prongs on the openings can be cut to adjust the difficulty, which is nice if you're using different sized kibble or treats. It is a little harder to fill than other toys, but still not terribly difficult. Overall I've had a great experience with all the PetSafe toys I've tried, and this one is one of the very best!

Great chew toys!
Color: Purple, Size: Medium (Pack of 1), Color: Purple, Size: Medium (Pack of 1)
Keenan LOVES this toy! He will play with it all day. Running around the house, chasing as it bounces in different directions. And he'll be so content chewing on it for long periods of time. It makes an annoying sound when he chews, but I can live with it if it's keeping him entertained. This is the second purple rubber toy from this brand that I've purchased, the other being the squirrel one, which was his favorite until I purchased this for Christmas. They are super durable, his squirrel is still going strong. Even without putting food/treats inside, these are great toys for dogs that enjoy the softer rubber type chew toys. My only con is that it's a little big for him. He weighs 70lbs and I got the medium. It's fine but he has a hard time carrying it because of its size/shape, and he can't catch it when I toss it to him. Think I'm gonna buy the small size to see if it's any better.
