Description

ImmersionRC RF Power Meter V2.1FPV is made possible thanks to two RF links, a control link, and a video link. Without an RF Power Meter, a pilot has no way to test these critical RF links. Test equipment for microwave (GHz) links is not cheap. ImmersionRC changed this several years ago and provided their Power Meter v1 to the FPV community.

FPV is made possible thanks to two RF links, a control link, and a video link. Without an RF Power Meter, a pilot has no way to test these critical RF links. Test equipment for microwave (GHz) links is not cheap. ImmersionRC changed this several years ago and provided their Power Meter v1 to the FPV community. The v2 is the result of listening to customer feedback. ImmersionRC added an internal battery, an internal attenuator, and other features that every FPVer needs.

Accurate RF Power Measurements

Is the latest whiz-bang hype-train vTx really as good as the datasheet claims? Does it really emit 25mW on all race channels? Does it still emit 25mW 30 minutes later?

The RF Power Meter v2.1 allows these questions, and many more to be answered.

Back in the early days of FPV racing ImmersionRC pioneered low-power racing, where everyone runs 25mW. This became a world-standard within a few short months and continues to be the standard today. The Power Meter v2.1 gives you the measurement tool that you need to test transmitters before you get surprised at the next race.

Touch-Free Race Compliance

Are you ready to test your video transmitter before the hammer comes out?

With the included stubby dipole, the RF Power Meter v2.1 is all that you need to perform a rough power test on any FPV platform, even without unscrewing its antenna. Calibrate the meter on a known good platform, and walk down the start grid testing each quad ready to race. Quads accidentally set on high power (hammer-ready), or those with hardware/cable/connector/antenna problems emitting a few micro-watts are identified before the first gate.

We call this Scully Mode for a good reason. Joe Scully, the best FPV MC in the business, perfected this test technique to ensure successful race meets on all four corners of the globe.

PowerScope Mode

So you know that packets of data are flowing from your R/C Tx, or Long Range system, to your model€¦ but what if you could see them? The PowerScope mode of the RF Power Meter v2.1 presents you with a visual representation of the power being emitted from your radio. How fast are they packets emitted? are the multitude of antennas on your radio working? where are they? what orientation? You can even spot transmitters which comply with LBT (listen before talk), or Duty Cycle limitations.
Yeah, it is a geek tool, but it does impress the opposite sex!

Average and Peak Measurements

Analog Video Transmitters emit a steady stream of RF goodness. R/C Controllers emit a stream of pulsed goodness (which just happens to be heading in the opposite direction). The RF Power Meter v2 can deliver accurate power measurements for both types of RF signals.

Integrated Li-ion Battery

The v2.1 contains an integrated Lithium Ion battery, which will power the meter for at least 8 solid hours. With auto-shutdown after periods of inactivity, a single charge will power your meter for days at the race track. Recharged using a standard micro-USB connector in less than one hour.

Best Pillow Ever
Color: Blue-ice Plus, Size: Queen(Pack of 2)
Best pillow ever. Although it still gets "hot", it does take longer to get "hot". I love this pillow. I was buying a new pillow almost every 3 months. Other pillows would either remain rock hard or go flat. I was concerned at first when reading the description as I though the memory foam would be big pieces. They are soft fluffy pieces. I had to remove almost half of the foam to get the pillow to what works for me. I have not had to put any filler back in. Maybe in a couple of more months I may have to put a bit more in, but it is holding it's shape and not going flat. I do fluff it every night. This helps. I am a stomach sleeper. I have bought the expensive purple pillow and hated it so much I gave it to my daughter. This QUTOOL Pillow is the best! I bought a 2 pack. Have not used the other pillow yet, but I feel I may actually go years for once without having to buy a pillow as I have the 2nd one set aside if the first one gets to a point in need replacement. I have bought Dollar Store pillows. I have bought $300 pillows. None of them even come close to this pillow and the way you can adjust this pillow for you. The pillows came in a white mesh like bag. I keep all the unused "stuffing" in this bag. I have it hanging in my closet and I just fluff the bag once a month to keep the filling fresh so it is ready if and when I need it. Coming from someone who has trouble staying asleep, neck issues, a stomach sleeper who hate those flat pillows manufacturers think stomach sleepers like but actually hate, buy this pillow. Just buy it. Best Pillow for a picky person like me. Buy 2 or more so if you have to stay at a hotel, you can take your own pillow.

Foam Mattress NEEDs Foam Pillows
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
10 stars!! Quality foam, structure & price. Best bang for my buck.    HRV, readiness & total sleep score metrics increased drastically this week.  See screenshot :) Support: Molds and cushions every crevice under my neck and above shoulders. So comfy  Size: Adjustable loft but king length is perfect to hug and rest your head.  Love love love. The 1st 2 nights were uncomfortable with pillow as is, first night I was up at 3am half asleep pulling foam out but wasn't enough. The second night at 2am I pulled out more stuffing. I was getting frustrated..  my Oura ring showed both nights I was awake every hour.  Not good.  Before the 3rd night I pulled enough to fill the bag the 2 pillows arrived in. Boom -8hrs sleep and for the first time ii years I achieved 17% Deep sleep.  Huge. Weight: Perfect weight with adjustment. Squishy and molds to b the contour of my neck and shoulders Softness: Like the baby bear.. just right.   Comfort: Very comfortable after removing 30% foam in both pillows. I actually now have enough to make a 3rd pillow, replace old foam, or adjust OGs, Still to early to measure.  If you have a foam mattress that contours your body but not your head you'll end up with neck and/or back pain from head being elevated- not sinking/molding the body into a foam mattress.

These are not sized correctly - beware
Color: Blue-ice Plus, Size: King(Pack of 2), Color: Blue-ice Plus, Size: King(Pack of 2)
Edit: I was going to return these pillows but the seller contacted me and offered a full refund due to the size issue without having to send the pillows back. I am happy with this and happy to keep them on a spare queen size bed as they really are nice pillows. Just the wrong size. pros: they are a nice pillow and the cooling feature is really great, and you can adjust to your liking cons: absolutely wrong size. Ordered King, tag says king, all measurements on listing and tag say 20x36, in reality they are more like 20x30. Definitely Queen pillows being sold as King. I did not see any reviews at first about size issues but after I got these and did a search it does look like others have had the same problem. A shame, would have given them a great review if they were the correct size
