How to prevent wind noise in a handheld Mic ?

I was wondering if there is good experience on how to reduce windnoise in a VHF handheld mic ?

It is highly frustrating when all the equipment is working fine, but they still cant understand what you are saying because of the wind blowing into the mic. (or you cant understand what somebody else is saying.)
Particularly at speed, this seems to be a big issue.

I understand that water blocking the slits of the mike may also contribute, but what about ideas on windnoise.
The TV crews on TV have these big fluffy things stuck on their mic's but I dont think this will be a great idea on a rib.

Any clever ideas ?

Thanks

Slow down before using the radio! Then you can shelter it from wind!

Doesn't have to be big an fluffy; a sleeve of open cell foam will help. Other than that, find a position that minimizes air movement on the mike (duck down below the windscreen, or put the mic inside the flap of your parka lapel) before transmitting. Not much else you can do, as far as I know.

I find it's usually water pooled on the speaker cone rather than blockage. Water droplets keep the membrane from vibrating with your voice, yielding a muffled sound. When it's wet, a quick slap of the mic face against your thigh clears that right up.

Well thank you for all your helpfull comments. I am surprised that nobody really sees this as a problem. I agree that slowing down will help but sometimes when you are travelling in a group of boats, you cant really slow down or shelter behind your console as you wont know where you are going.

I also thought about some kind of cellfoam solution but I thought somebody else must have found a much more practical solution ??

QF,

I've never had a problem being heard by others, but at any sort of speed I struggle to hear others clearly. Because of this the automatic response is to slow down when using the radio anyway (and because you have fewer hands to steer / work throttle!).

If I was in a situation where I expected to need to talk whilst at speed often then I'd probably look at ear pieces. I've never considered the wind noise on "my" mike before - but I guess if it is an issue then perhaps the bluetooth headsets Bruce B was discussing a few months ago might help - especially if they are inside a helmet.

Ive bought and used ear pieces for my handheld vhf, worked well, I used for safety boat/regatta, cost about 15 each.
Just watch you volume control, someone always shouts in your ear.
