what is the range and distance of 2 Cobra marine submersable MMR425
364440
Hi I am not sure the total range. But I use it on ships because I am a harbor pilot. I am not a fan of it. It is very heavy. For me it seems it is best when in line-of-sight. They make this one in a lighter version that has orange on it. I wish I spent less and got a lighter one. This is NOT worth the price.

I use this radio regularly in a marine environment. GMRS range I have gotten about 2-2.5 mile range on average (this is over water distance for me). Marine is a much more difficult range to give, but I have had ranges over 20 miles on Marine VHF while talking to the Coast Guard (though they have really big towers on their end).Not what you asked, but I must say submersible is a loaded term. I am on my third replacement because the other two failed after submersion. (Though COBRA made the replacement process very easy, but reliability would be nicer.)

I returned my unit for a refund. The range of any radio will basically depend on the terrain in which you use it. Hilly/mountains etc. about a mile or less. Flat or low-rolling land about 1-3 miles. This radio just didn't perform as I had expected. I bvought a Midland unit which was three times better.

The answer for any handheld VHF/UHF radio is highly dependent on terrain and other barriers to the signal, like buildings. On flat land or on the water, I think you could expect a maximum 4 or 5 miles between handhelds. Heavy woods, hills, or urban environments can reduce the range to half a mile or less.

That depends on the type of environment your in. I have had up to 5 mile reception on marine side and up to a couple miles in GMRS in city environment. I'm sure both would be better if on the water. I give the radio 4.5 stars

Range that I have tested to is about 100 yards (Can hardly tell direction of the car). I don't have a boat. It is not water proof on its own the receiver needs to be in a sealed box and the controller I would not say is water proof either. Hope this helps it's a good controller for a great price.

I'm not sure I understand the question , but this is a great unit.I resold the 83/200 because works better in fresh water.If you use in salt water it is for maxis out at 300 feet .The 50/200 maxis out at 1000 feet but is no good for fresh water.

According to my manual Transmit frequency range is 144-148 MHZ. It won't hit the marine band. If U want a Marine band radio, look for a radio specifically made for the MARINE BAND. It is field programmable for the 2 Meter Amateur band.Tom, KB9KEC

I would say about 20-25 ft. I use mine on a belly boat and drag it about 10-15 ft away from my boat. This is a really neat device, however they could improve the blue tooth capability, which I do believe will improve with future updates.

20-25 ft. distance is what I have been able to get. Beyond that is very iffy.

I am based 10 miles from the Gulf of Mexico. This is a cheap Chinese built unit. the "water" pan shows signs of corrosion and the door seal needs constant cleaning. The unit is in a counter, under cover on a lanai within a protected pool cage. It is well protected. see my review on its failure after 14 months.

Yes I have installed three of them in a marine environment. The rudimentary problem is with the coaxial connection. It is faulty. As a marine engineer I find it sub standard. I believe, without going into my shop, the diameter is 13.125 inches (13 and an eighth). I believe it is functional but do your self a favor and replace the coaxial connector! You can get the tools and parts at any big box store fore cheap money without that fix it will be undependable.

The rating in the device is IP66. The second '6' means "Protection against string water jets and waves." For 20 foot depth, you'll need IPx8 where 8 = "Protected against prolonged effects of immersion under pressure." IPx7 is only good for temporary immersion to down to 1 meter.

I'm only using 4w (FCC reg.) on a Cobra 18 WX ST II in Red Bank, SC and have reached Gaston, SC 10 miles away.. With only a 3ft version. I put my Antenna up about 13ft, and have a large ground plane. All Homemade.

I think about 70 or 80 minutes at full throttle. The distance will depend on what size boat and how much load you're pushing at what elevation. With three adults on an Intex Mariner 4 at 6000 feet above sea level I can go about 6 miles on a tankful. The lower the elevation the higher speed and longer distance per tank.

The range is very well when looking through them in open water , which Is mainly what I bought them for navigating. And focus in very well for the price and the quality of them. Only problem I've had is using the range finder and formula given to figure out the range away other that just using a radar for the target I'm looking for .

Depends on the antenna you use. I used this radio several times in a caravan with another person who used a Cobra CB with roof-mount antenna, as well as some semi trucks. Here's what I found: Included "rubber duck" antenna -- probably 1/2 mile to 1 mile on straightaway, a few car-lengths on curves. (use "low" power to reduce echos) With 29.5 inch mag-mount CB Antenna from RadioShack (fine-tuned with SWR meter after install), about 1-2 miles (use high power) With 102 inch chassis-mounted CB antenna from RadioShack (fine-tuned with SWR meter after install), I reliably and comfortably chatted with trucks at 5-7 miles or my driving buddy at 2 miles (use high power) For comparison, we tried using FRS "family" walkie talkies and they would only work when we were immediately following each other without any curve or vehicles between us.

The information you are looking for should be in your Cobra instruction book, If not e-mail Cobra.. Get on their web site. If you have the cable? Should work.
