My brother has sold and been an agent for all the main brands - for 4wd use - and has used them in the field and in off road comps for 13 years. He has always had GME and Uniden over the years, but in the last few years has moved towards Icom. I asked him which one and he didnt hesitate and said spend the extra coin and get the Icom. So I did and very happy with the all in Mic unit. Mine is the IC-440.
Cheers
