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.
The crucial part is " above eye level" - the point I am trying to make is that the Radome must be above head height - not only for safety but also for increased range.

Some Ribs I have seen do not fulfill such criteria and to me Radar mounted so low is a waste of time and dangerous(unless you remember to crouch down low)!!!

Of course I agree that Radar is a huge safety aid - would definitely fit it to a cabin type RIB or a commercial one with a high Radar arch!!!

The problem with radar is interpriting what you are looking at, at that takes practise.

Couldn't agree more - just remember to duck if it's down low............

It is strange to think that RADAR hasn't really advanced that much since the magnetron was invented during the war - alright the displays are better and much smaller but power/range etc are still the same - also the skill required hasn't really changed that much!!! Electronics can only do so much.

I seem to remember my Raymarine manual was particularly concerned about damage to eye tissue rather than brain tissue.

Brian cells Radars and Ribs

Well gentlemen ,

thank you all for the information........I have decided to go for the Raymarine C120 as per our Demo cabin Rib.

To alleviate all fears about killing the grey matter The radome will be mounted high on the second A frame Mid Ship to allow for the stability and of course range.

For those who are curious to look at the A frame set up take a look at our web site www.parkerribs.com and view the Baltic 750

Any views on this twin A frame set up are also welcomed.

Any chance of getting a slightly higher A-frame. It still looks a bit low to me if the brain fryers are to be believed.

Everyone else as well as David B.
I still maintain there isnt a problem. No expert has come on here to tell us that we are going to be death-rayed. The HSE police are quiet on the subject. Nobody has posted any actual anecdotal evidence of damage to humanoids.

I reckon we are OK.
