Harold, Most units rated at JIS-7 also pass the CFR-46 test but that's not a given since the two methods of testing are so dramatically different. Our RAY102 and RAY106 (rated to JIS-7) also pass CFR-46. I believe JIS-7 does have an edge but CFR-46 is a close second for paddling applications. It all boils down to, as usual, how much you want to pay. A JIS-7 radio is more expensive to design and manufacture than a CFR-46 radio. I hope that answers your question. Cheers.

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

Mr. Stohrer, I am a subscriber to Paddlewise and I wish to thank you for taking the time to educate us regarding the waterproof standards for radios. This really is most wanted info. I have some follow-up questions. We have had some people report problems with radios and GPS units which were deemed to be waterproof. It turned out that the units were indeed waterproof, however the battery compartments were not. Can a radio claim the JIS-7 rating with a battery compartment that is not waterproof? Do the battery compartments on your models RAY102 and RAY106 perform in a waterproof manner? Thanks, Bill Leonhardt *************************************************************************** PaddleWise Paddling Mailing List - All postings copyright the author and not to be reproduced outside PaddleWise without author's permission Submissions: paddlewise_at_lists.intelenet.net Subscriptions: paddlewise-request_at_lists.intelenet.net Website: http://www.paddlewise.net/ ***************************************************************************
