Hi everyone. I'm JP Stohrer from Raytheon Marine. Just wanted to respond to Steve's submission and put my two cents worth in to explain some of the waterproof acronyms you see flying around. JIS-7: Stands for Japanese Industrial Standard 7. A unit with this rating can be submersed for at least 30 minutes in 1 meter of water without water intrusion. This is quickly becoming the industry standard for handheld VHF's. Our RAY102 and RAY106 meet this requirement. JIS-6: Japanese Industrial Standard 6. Not quite submersible but considered waterproof. JIS-4: Japanese Industrial Standard 4. Basically splashproof (so don't get it wet). IPX-7: Similar to JIS-7. I don't know the meaning of the acronym. CFR-46: This refers to the US Code of Federal Regulations, title 46. Title 46 contains Coast Guard requirements. Part 110 of that title provides a definition of "waterproof" that says a unit must be able to withstand 65 gallons of water per minute through a 1" fire hose from a distance of 10 feet for 5 minutes from all sides. I've witnessed this test at our UK facility and it is impressive. MS810D: This is one that Standard Communications sometimes uses. I'm not sure exactly where this comes from but I believe it is the next step down from CFR-46...... but don't quote me. You'll also see references to "splash resistant", "water resistant", and such but those should definitely be kept in a drybag. Now after all of this, does a CFR-46 rated unit need to be kept in a drybag? Depends on the usage. Although I do recommend JIS-7 for paddlers (RAY102 or RAY106), the RAY100 should be fine in most conditions without a drybag. The only exception would be if it was kept in a compartment that has standing water. The RAY100 will take splash and rain with no problem at all. But as with anything else, the better you take care of it, the longer it lasts. Preference of the user. I hope this helps. If anyone has any specific questions, just shoot me an E-MAIL at John_P_Stohrer_at_raytheon.com.

Since the test modes are so different, any comments about which of the above two standards would indicate the most bombproof radio?
