PowerMax Long Range Collar

thumb_PowerMax-collar_logoThe longest range tracking collar for Hounds, available anywhere, this  collar runs for months of normal use on common AA batteries. This means you can get your batteries almost anywhere and they don't cost $8 to $12 each! Collars run for over 700 hours on new set of batteries.

A small LED flashes green during normal use, and switches to red to warn you when only 5 days of life are left. You'll never again have a collar quit on you with your dog out in the woods, because you didn't know the batteries were almost dead.

Machined casing with tripled sealed waterproof construction for years of heavy use. The magnetic switch does not need the magnet strapped to the collar, but only requires a tap to turn on and a tap to turn off.

Best of all, the PowerMax is availible in any frequency you need from in 150.005-155.995, 173.005-.995, and 216.005 to 217.995.

Available frequencies: 150-155, 216, 217 and 173 MHz
Available light colors: red, amber, green, blue

Key Features

The case on the PowerMax Hound Collar is machined from a very hard aluminum alloy, not plastic. Therefor it cannot be cut or crushed like plastic. We start with a solid block of aircraft aluminum alloy and with several operations, work it into a precision piece of smooth sculpture that hugs the dog's neck with a curved design, unique to Marshall collars.

In one instance, an F350 pickup was driven over the collar with no damage, other than a slight rock mark on the side.

In the tracking collar market, every design seems to use specialized batteries in order to get the power needed for long range. While there's a good reason to design around some of these energy-dense batteries, there's also a downside: they are expensive and can be hard to find when you need them.

Our engineers found a way to get even longer range while still using common AA batteries. This means that you could drop in to any Convenience Store on your way out of town, or even a Wal Mart at three am, and find new batteries when you need them.

It also means that these collars are the least expensive to operate. In just a short time, you may save enough in battery expense to buy a second collar.


There are two great reasons behind having the high-intesity safety lights in your collar:

1) To be able to see what your dog is doing in the dark when you are within close range. Being able to see his movements, and direction changes, is a valuable thing with a young dog still in training.

2) As a protection out on a highway or County Road in the dark. Many customers have already proven that the Safety Lights have caused vehicles to slow down and brake for their dogs when they were nearby or crossing the road.


Never again will you lose a dog due to having the batteries go dead while out on a long hunt. The PowerMax collar keeps track of the battery voltage and warns you two ways (with a double beep on the tracking box and a red light blinking on the collar) so you'll always know when it's time to change out the batteries. When you hear the collar go into double-beep mode, you still have about five days of tracking time left so there is always that margin of safety every time you turn loose.


The anttenna has been carefully designed to require no special tools so that with a pair of snips, you can easily change out the antenna by hand with a new one. There is no need to send the collar back to the factory to have this done.


The PowerMax collar is triple-sealed so you can use it with confidence when you hunt around around swamps, lakes or creeks. The battery compartment is sealed, and all the elcetronics are completely sealed.


Your new PowerMax collar is backed by a Three-Year Warranty. If anything goes wrong with it, simply return it to us and we will qucikly repair or replace it.

Intended use


The Treed switch is designed to let you know when your dog is up vertical, and is not confused by hills. This collar design can take the ongoing heavy use and abuse that tears up most every other collar out there.


The PowerMax collar is much smaller than regular Hound collars, weighing only 5 oz with lithium batteries, yet still gives big performance.


Designed as the longest range Hound collar you can buy, the PowerMax collar reaches out in hill country and through swamps better than any other tracking collar on the market.

Where Houndsmen have a GPS collar, the Powermax is used by many as their "backup" collar as insurance for them when their dog gets out of range. They also prove the best insurance when Hunters have to turn off their GPS receiver during a Nite Hunt Competition, and the dogs get out of range so that when they turn back on and have only a question mark on the screen, they can still have their "beep-beep collar" tell them which way to go.


The PowerMax collar has saved dogs in the most extreme situations where a weak collar or a GPS collar would be the same as lost. One customer had his hound enter an unexpected small cave in an open field, follow a coon underground and get stuck for two days. However, he had a signal pointing straight down about 200 yards from the entrance, and hired a well driller who punched through 17 feet of rock to find the dog and save him.


Using the high-intensity safety lights certainly lets you see what the dog is doing, but having bright lights on the collar has already saved a large number of dogs out on remote highways at night.

Customers Say

"One of the super good things is that your little light tells you when the batteries are getting weak. That's one of the big downfalls of the other collars, cause they can be working fine, and an hour later it's just dead. You got it then you don't and that's real frustrating to a hunter to be beeping his dog and then be getting nothing. I've had one and I've sent back several times under warranty, but doesn’t help you when it’s gone for several weeks.

"My old Johnson collars just keep getting weaker and weaker till it's gone, but that light on my Marshall collar tells me when it's weak and then all I have to do is reach in my truck and change 'em, I don't miss the hunt, I don't have to be without it several weeks. Those others, if you use them they're going to go out and have to be sent back long before the warranty out."

Marshall Loftin, LA

"I've tried just about all the brands... and there's no comparison. Marshall collars have a stronger signal and better direction, and use the easy to find, inexpensive AA batteries! And their receivers have amazing sensitivity and a three-step attenuation switch (Near/Medium/Far) so I can tell how far out my dogs really are. Quite simply, I go straight to my dogs.. and FAST ! Thanks Marshall Radio!"

Steve Lithgow, Way Cool Kennels

"I cannot begin to tell you how well the Marshall products have worked for us this year. At Grand Valley Kennels, we’ve tried all the tracking devices available on the market today. We can truly say with all sincerity, Marshall products outperform any tracking devices we have ever used. In a recent hunt, our dogs got deep very quick. We were able to not only track our dogs, but we were able to do so with pinpoint accuracy. When we finally got to our dogs, we were 8 miles from where we started!! In our neck of the woods, that is simply unbelievable! So it is easy for us to say that Marshall Radio Products are the absolute best tracking devices available. Simply put.... Longer range, pinpoint accuracy, less problems with collars and a company that stands behind its products. What more could you ask for. It's like this. You can track your dogs or you can spend all night trying to track your dogs. The choice is simple.... Marshall Radio Systems. The serious hunters' choice."

Tim Amey, Grand Valley Kennels

"I’ve used Marshall for 5 years now and this is the best system I’ve ever used. It’s got more range and yet it’s also easier to pinpoint the dogs. You can move it just inches to each side and tell, my friends that are with me are always impressed as hell. It’s pretty damn accurate. At first, I thought I’d have trouble with the quick-deploy antenna if I didn’t handle it with kid gloves. But I’ve used it (not abused it) for two going on three years, and it’s just click, click, click, open and close. It’s pretty damn durable."

RJ Marquart, Quick Silver Kennels

“Over the years, our agency has used every tracking system available, but when we started using the Marshall system last year, we were at first impressed with how small and tough the collars were. Others were made out of plastic, these are machined aluminum. Now we’re most impressed with how much range we get out of them. It’s just incredible. I bet over half the guys I watch using those tiny receivers head out in the wrong direction. Other friends still use the big blue box hanging around their neck and the hand-held yagi antenna with wingnuts. With my Marshall receiver, I’ve got the receiver out, found the signal, put it back in the holster and on my way while they’re still screwing together their antenna. Now they don’t even try, they just say to me, “OK, where’s the damn dogs.”

Tri-State Wildlife Management

I truly like your collars and so far nothing I have ever been around has tracked nearly as far. I always track one of your collars when my hounds get real far from me. The other day a hunter was with me and flipping through collars numbers and most of the hounds were real close. When he reached the hound that was wearing your collar he made the comment this hound must be in the truck! He even began looking right by the truck for him. I had to laugh at this and proceeded to explain the difference in collars. When I need to buy more collars you can bet I will be buying them from you.


I just wanted to let you know I am well pleased with the 2 collars that I received last week. They have great range 14 miles compared to quick track QTC XL .6 miles. And I like the design since it's not as bulky. I will be ordering more soon! Thanks

Q & A

Which is better to use in this collar: alkaline or lithium batteries?
Common AA alkaline batteries at 50 cents a piece are hard to beat for convenience and availability. But you can find AA in lithium (photo batteries) at most camera counters now, and they are extremely lightweight and last longer. The trade off is they do cost more. Both work well.

How long does it run on a set of batteries?
About 700 hours of tracking, and between 7 and 14 nights of hunting with the lights turned on.

Does it matter which type of AA batteries I use?
You can use any of the common batteries you'd find at any store, Energizer, Duracell, etc. Rechargable AA's are not recommended.

How far will it reach out there? What's the range?
There are many things that will affect the range, such as dense vegetation and mountains. But customers tell us they get anywhere from 25% to 50% more range than any other long-range collar in their hunting area. It's designed to be a very long-range collar and with a good crisp signal.

How does it turn on and off?
With the tap of a magnet, any magnet. You tap it once on the On/Off mark on the side of the case and it starts running. You see this if you're receiver is not on, because a tiny green light flashes on the collar. You tap it again to turn it back off. You tap the opposite side where the Light Bulb mark is, to turn the three bright lights on. Tap there again to turn them off separate from the tracking transmitter in the collar.

Will it work my receiver, the box I already have?
Yes, if your receiver is able to pick up numbers in any of the common bands, from 216.000 through 219.999, we can give you a number to match. We can make them in sets or set them to avoid collars you already have.

What's the Warranty on these collars?
Three years. There's also a 30-Day Satisfaction Guarantee where you can get a refund for any reason, provided the equipment is returned in like new condition. This allows you to test the collars to be sure it what you really want.

Can I get any number (frequency)?
Yes, we can send them to you in any number you want between .000 and .999, just let us know during checkout if you need a particular channel number.

What do you mean by "Down Dog Mode?"
There is another activity sensor in addition to the standard Treed switch the detects if your dog has not moved for 5 straight minutes. At that point, the signal slows down and the collar emits a longer pulse. This tells you that maybe something's gone wrong and you ought to go find the dog or collar immediately.
