Antigravity Batteries Micro-Start XP-1 Now Available at Radioworld

Radioworld is excited to announce a new and revolutionary product to its ever growing line up.  The Antigravity Batteries Micro-Start XP-1 are now in stock!

The Micro-Start XP-1 is a pocket size Extreme Power Lithium battery jump-starter and back-up power source for vehicles and electronics!

Whether you are riding, driving, camping, boating, snowmobiling, on your ATV or hiking, the Micro-Start XP-1 is one of the most important emergency power items you will ever purchase. It offers safety and security in a world where we rely so heavily on our electronic devices and vehicles. The XP-1 fits in your backpack, glove box, storage compartment or pocket. It is truly a go anywhere device.

Weighing less than a pound (14 oz. or 400g) and small enough to fit in your pocket, you can take it with you anywhere and remain confident that you will be able to start your vehicle, make that important call, or power other electronic devices on that long trip or outdoor adventure.

It also has a built in flashlight with S.O.S patterns!

The built-in Extreme Power Lithium battery can hold a charge for up to a year and not only jump-start most Cars, Trucks, Motorcycles, ATVs, Snowmobiles and Watercraft multiple times, but can also provide hours of backup power to most of your electronic devices.

“Please note, some vehicles with highly sophisticated electrical systems may not jump-start using the MICRO-START.”

Does this all sound to good to be true? We thought the same thing, so decided to test it ourselves at Radioworld. We took our president’s BMW M3 and disconnected the battery. We then connected the Antigravity Micro-Start XP-1 battery to the car. To our amazement it started on the first try. We then shut off the car and repeated the same test 3 more times. The car started every time, each time with absolutely no trouble at all. With portable emergency power like this, in such a small package, you’ll never be stuck for a boost or emergency DC power again.

The Micro-Start XP-1 also has the following features:

– Charges and powers most electronic devices, including laptops.
– 3 on-board Power Ports: 19v for laptops, 12v standard output for all 12v Accessories, USB 5v output for charging or powering ANY 5v USB standard charged device.

NEW Hydrowave Mini

HydrowaveThere is a really cool new product coming out from Hydrowave in the next month or so. It’s going to be called the Hydrowave Mini and is geared towards anglers in smaller boats, kayaks, shore fishermen, etc. This will retail for under $130.

Here are the details on the Hydrowave Mini that I have so far…

2 Sounds pre-programmed which are Passive Shad and Shad Frenzy (the two most popular ones).

There will be an 8′ cable from the control head to the speaker.  There will be a volume up/down and pause and play buttons on the control head.

The Mini will be powered by a 9 volt battery and should last about 6-8 hours.

This sounds perfect for ice fishing as well!

Garmin’s New echo Portable Kit

We are excited to announce Garmin’s new echo 150 Portable Bundle and Portable echo Kit. This portable solution is perfect for anglers who go from boat to boat, or those who fish from small vessels, kayaks, canoes, docks or even through the ice.

The soft-sided carrying case with rigid support arm fits any model of Garmin echo fishfinder, and includes both a sealed rechargeable AGM battery with smart charger and a suction cup transducer mount with float.

The bundle includes an echo 150 with dual beam (200/77 kHz) transducer. The echo 150 features an 8-level FSTN grayscale display, Garmin HD-ID technology, 200 watts of transmit power and wide viewing cone angles (60°/120°) to help see more fish.

The portable echo kit offers existing echo users an exciting portable solution – just add their echo fishfinder, charge the portable battery and they are ready to fish. The entire kit fits conveniently into a 5-gallon bucket so they can easily take it all with them!

We should have these in stock sometime in November.


Get your Electronics Ready for Ice Fishing

I can’t tell you how many times ice anglers come into the store once the season starts and I hear, “My unit worked before I put it away but when I took it out this season it won’t!”.  Now is the time to double check all your ice fishing equipment is in working order so the first trip of the year isn’t ruined.

The most common issue we see is a dead battery.  Batteries that have been put away without a full charge, or not charged at all during the summer, could end up dead and unable to take a charge when you try and charge it.  Battery maintenance is very important for underwater camera’s and flashers.  We recommend charging the battery after each use and maintaining that charge at least once a month when the unit is not in use.

Should you run into a problem where your battery isn’t taking a charge, or its just time for a new, one we have replacements in stock.  They are available with or without a charger.  The DSC100 is a great product from MarCum to ensure your battery is maintained properly.  Its easy to read digital display and automatic shutoff feature makes battery maintenance a breeze.

While there is no way to accurately test a transducer out of the water without expensive diagnostic tools there is a way to get an idea if there might be a problem.  First, check to see if you can hear or feel the transducer pinging (sounds like clicking or feels like small pulses).  If you can’t hear or feel it that may indicate a problem with your transducer.

The second way to check it is to hold the transducer about 3-4 feet off a hard flat surface (like a concrete floor).  Turn the gain up until you see a reading about 3 times deeper than the distance from the transducer to the floor.  If its 3 feet off the ground it should read in the 15′ range.  If you keep turning the gain up you should see double, triple, or even quadruple echos.  The more echos you get the better the reading.

These are a couple of quick things you can do to check and make sure everything is ok before hitting the ice this season.  We stock batteries, chargers, transducers and just about every other accessory you may need for your underwater camera or flasher!
