Hi there ,

Thank you for the reply, can I ask what exactly makes it a more robust commercial set. Is it the casing , waterproofing etc. and finally how much is this set.

thanking you

I just can't believe the people who liken boat radar systems to mobile phones - of course the frequencies are similar but what about POWER - a few milliwatts for a phone - RADAR has peak power of about 1.5kw - yes that's right - just like a microwave oven - same technology - a magnetron and waveguide - would YOU open the door of your microwave and use it - I wouldn't!!!

Microwave ovens came about because RAF pilots noticed their sandwiches getting hot in the lockers near the Radomes.

Of course with the inverse square law the power drops off exponetialy with distance but even so - I certainly wouldn't risk it.

There are plenty of documented cases of Yank Police getting testicular cancer from their radar guns - keeping them switched on in their laps whilst waiting for speeding motorists!!!

Why not, the yachtie magazine was trying to put things into perspective for those of us that don't have an hons degree in Physics.

yes this was their point, mobile touching your ear or radar 1 metre away.

oh I would, caught out in fog or rain especially at night time I would have no hessitation in turning the radar on. Bit of an over kill for a jolly around the Solent on a sunny day, but having been caught in fog on a number of occasions its very easy to become disorientated. The problem with radar is interpriting what you are looking at, at that takes practise.

Hi

The Furuno radar isnt on my boat but is fitted to i commercial boat that i sometimes work aboard.

Price wise, i heard talk of a couple of 'k' although dont quote me as it was fitted with a number of other items so im not sure of the exact cost. All i know is that it was quite pricey!

Id give a dealer a call and check it out...

As for quality, its in a wheel house so hasnt been subject to water but the whole unit seems very chunky and well made compared to its competitiors. I just personally feel that it comes across as being a very well made, heavy duty set that is built for work and will take some punishment - and of course it does all three essentials in one with overlay!! Echo/plotter/radar which saves valuable space!

Do a search, there was a thread a while back which compared Furuno and Ray kit.

Cheers

why not go for the Raymarine C120 . The same unit which you so enjoyed operating during our sea voyage to Poland. Also the 750 Baltic which you so refered to is also fitted with the C120. Why change to something different, it is a very good system and you know how it works

It definately says power output is in low watts not KW.

Sorry to disagree but I read it as 2KW peak output power. Power consumption is low watts.

Brian,
I believe the output power is 2KW. However I found this on the site.
Question
---- 08/02/2001 11:22 PM ---------------------------------------------
Please discuss the biological radiation hazard of a generic marine radar. I see a lot of questions on my listserv on this subject and most of the answers offerred are somewhat surreal and appear totally overly cautious. If possible I would like a technical answer so that I could pass your reply to my shipmates with some credibility.

Answer
At 08/03/2001 12:12 PM we wrote - Due to the relatively low power of leisure radar, concerns over harmful transmissions are generally not considered to be a problem as long as people are a few feet from the scanner unit (about 3 feet) and the scanner is positioned above eye level.

The following is an excerpt from our Radar handbooks discussing Radar safety.
