Cell coverage can be spotty along some shorelines and non-existent if far enough off shore.

Using a VHF gives paddlers access to Channel 16, which is monitored 24/7 by the USCG and commercial vessels. Channels 67 and 68, for example can be used for nonemergency communication betw. vessels, even two groups of kayakers. I have seen trip leaders on Lake Superior confer via their radios. They agree beforehand which nonemergency channel to use.

Equipment is no substitute for skills and judgement. But if you need to communicate status and position, a VHF is overwhelmingly better than a cell phone. Plus a VHF w. a waterproof spec of JIS 7 or 8 will work when submerged, a cell phone? not likely.

Here is a link to a quick overview of JIS ratings:

Still can't figure out where to keep the radio on my person without it being in the way.. No real place on my back to clip it on my Solquist. I think Kokatat has a new jacket coming out I will look at and see if there is any where good for the radio.

Just bought the newer model Standard Horizon today as I thought the one I had was messed up. Turns out is was locked on 16. Now I have two one for the boat and one for the kayak. I could have one for each kayak if the GF is with me or take both if I am going long next year. New one has nav in it also. They have decent basic radios for 85 and they all have 3 year warranty. I could also call the GF when coming near the house for dinner update.
