What is Reddit's opinion of Astatic (302-PDC2) SWR/RF/Field Strength Test Meter , Black?

From 3.5 billion Reddit comments

For these types and a 25 watt car transceiver should i get a antenna tuner or at would it be worth it? like this one https://www.amazon.ca/gp/product/B000KEUFME/ref=s9_simh_gw_p263_d0_i2?pf_rd_m=A3DWYIK6Y9EEQB&pf_rd_s=desktop-2&pf_rd_r=TKWXQZQHK4EJ9YC7J50B&pf_rd_t=36701&pf_rd_p=2055621962&pf_rd_i=desktop#productDetails

I will try to address all of your questions:

1. SWR (Standing Wave Radio) meter measures the efficiency of your antenna, higher the number the worse its doing, it will affect range and could even damage your radio if its too high.
2. The internal SWR meter will work but an external is always better. You can pick one up for ~$20 on Amazon, just make sure it either comes with or you buy a jumper cable (short usually six inch cable for connecting the radio to the meter). This is the one that I have used (link)
3. The Wilson Little Wil is a decent antenna. As long as you are not trying to get maximum range (i.e. you just want to use it for local, like find out whats happening on the highway sort of thing) then you will be fine.
4. As far as mounting the quickest and easiest is to get the magnet mount. Put it dead center on the roof of your vehicle. This will give you the best range and an even signal all around you.
5. Finally for the power again go to amazon and get an adapter for your cigarette lighter. Something along the lines of this (link). Strip the CB power cable and the adapter and solder together (red to red, black to black).

For help on tuning there are many good videos on youtube. Additionally if you need to order things take a look at Right Channel Radios. They have all of this (antennas, meters, radios, mounts, etc.) and they have nice instructions on how to tune your antenna.

Let me know if you have any other questions. Always happy to hear people are getting into CB. Would love to see it grow again.

I was looking into this one I found on Amazon https://www.amazon.com/Astatic-302-PDC2-Field-Strength-Meter/dp/B000KEUFME/ref=sr_1_4?crid=WL7U0B4DUP5R&keywords=cb+swr+meter&qid=1556484543&s=gateway&sprefix=cb+swr+%2Caps%2C157&sr=8-4

Is this a good meter, or is there a better one you would recommend?
