Radar options

We need to replace our old radar and have several choices. First I should say that we rarely use the radar and it was on the fritz from Australia to South Africa and there were only a couple of times where we felt like we were missing it. In tropical and semi-tropical areas it is nice for seeing a way around storms. When we return to temperate areas where fog occurs it would be good. Also good if we want to go to Namibia next year since it is foggy there. Anyway, the short version of the above is that I don't want to spend too much.

The options seem to be:
1. Get a radome (non-digital) that I can link to our 'classic' Raymarine chart plotter. Would have to get one on eBay since these are no longer made.

2. Get a Furuno monochrome radar, model 1715. Are these weatherproof for installation under dodger?

3. Get a Lowrance HDS system which apparently has very low power consumption.

4. Get a Lowrance dome and a Standard Horizon display. Does the SH display have any advantages?

5. Get a Ramarine e7 system which seems to offer some interesting networking capabilities.

What do you think?

Go with the Raymarine setup. I've looked at many in the last two months and Raymarine has the edge right now. Defender has a deal on item #259576 if you want the e7 and the radar unit is packaged in. You have to look at the price in the cart, not the listed one. Be aware this is not the HD radar, but on a 7" display you wont know the difference. The e95 would would be a step up with HD radar, but it will cost more too.

Re: Radar options

I'm a fan of Ray, but is simrad has a huge edge with the 3G broadband stuff they have on the market right now.

Re: Radar options

I'm old school and prefer stand alone instruments, and I'm also a big fan of Furuno radars. I've had several (mostly the CRT models, and one older LCD) and all have been excellent and completely reliable. Having radar overlaid on the chartplotter would be great, but if the chartplotter display dies...
The 1715 is weatherproof so it would work under the dodger. Here is a link:

Re: Radar options

Don't matter what get one with MARPA. I had one with the system and now I have one without. It makes a huge difference.

Re: Radar options

Just did the final spec sheet on new boat. Went with the Ray HD 48m with the smaller dome. It has less draw and weighs less. It's going on the mast so mounted on a self leveling mount to make up for the smaller band width. As regards chartplotters - put in several. Any one of them can serve as "master". Can see output from any input on any chartplotter or the smart phone/I pad. Redundant redundancy. I think new networking boat systems make dedicated single use screens unneccessary. Remember at looking the north up green haze under a hood and having no idea what was going on.
P.S.- still have a meteoman,sextant, sight reduction tables lead line etc. but amazed by the new technologies.

What do you think?
Your list is diverse in both price and technology..
1)
Probably the least expensive, no experience with those radars.
Sure it is the old radar that is the problem?

2)
Standalone systems is just that... If you want to have radar & chart plotter at the same place - do you have room for both. Don't think that you will find stand alone radars with the newer technologies.

3)
Lowrance, Simrad and B&G are all companies in the Navico group Navico - Leader in Marine Electronics
All these brands share the same radar technology Broadband 3G™ and Broadband 4G™.
The broadband technology is different from what the others have. Broadband is better for detecting targets close, not so good at detecting squalls read more here. http://www.lowrance.com/Global/Lowra...Guide_3406.pdf

4)
Can you combine Standard Horizon with lowrance radome?
I don't think you can, radars can't use NMEA (0183/2000) to transfer radar pictures to a display - so all of these use proprietary protocols.

5)
All the suppliers have "interesting networking capabilities" in the newer models.

Some points to consider
Budget
Stand alone
Integrate with existing
Replace existing

Which features are most important?
For radar Broadband/HD/Marpa/arpa?
For chart plotter integrate with AIS/VHF/sensors/autopilot

Not an answer - but hopefully food for thought

Re: Radar options

If you decide to stay put and go the least expemsive route I have a an in the box Raymarine analog Radardome which I am selling for $600. It was installed for 2 days on the boat with our old C80

I have a newer c95w so I had to replace the radar as it wasnt compatable.
