Speedo and sounder query

[robrib]

I've almost completed the restoration of my old Searider 5.4 and I'm dying to get it in the water. I've now got a blank console and about to install electrics. As I'm new to ribbing do you think for navigation purposes I would be better starting on a basic speedo/log and sounder(if so what types). Or should I push the boat out and go for a gps plotter/sounder. My budget is about 300 -400 quid. Any advice would be most appreciated.

If you want a plotter, remember to budget for the cartography too.

I went with both, and it was a great choice. It saves time & fuel on longer passages because you can avoid weaving about your desired course.

I'd get a plotter 'cause that'll give you the exact speed without need for a pitot type tube (inaccurate - I found) or save you having to drill a hole for a paddle wheel (never seems a good idea!)

You can add the depth later for under £100 (i'd buy a fish finder - I think its the same money)

If you look at the chart it'll give you the depth contours anyway.

Budget options to consider:

Navman 4150 Fishfinder (speed distance depth)............. £125.00

Lowrance M52i (GPS/Sounder speed over ground/ depth)..£209.00

Jump to a chart plotter will cost in the order of £450 minimum )including cartography)

I reckon if you search around a bit, you could probably find a combined GPS plotter and fishfinder for not much outside your budget (but then you'll have to start saving again for the maps!).

Search on ebay/internet - be careful though:

(i) some of the units advertised cannot take external cartridges, and the 'background maps' are only useful for the US

(ii) be careful of 'GPS ready' fishfinders - which require add ons to become plotters... what you require is a combined plotter/fishfinder

(iii) GPS units sold from the US may only have a background map for the US - which will make the unit a bit useless as a plotter until you buy the Map cartridge. I would still work as a fisfinder/depth sounder, and basic GPS unit though.

(iv) check what type of cartridge the unit takes (ie Navionics, c-Map) - then check the catalogues of these cartridge map suppliers to be sure that cartridges are available with the correct level of detail for the areas you are interested in..

Probably a good idea if possible, when buying off the internet to buy from a source as close to home as possible (ie UK based...., better shipping times, UK compatible gear, support you home economy, and also for some odd reason - maybe a better feeling...). I bought a Lowrance 320DF (combined GPS plotter and fishfinder) for something around you budget (I forget exactly...) from a UK supplier on the net last year - works great.

I've just imported a chart plotter & sounder from the US. You might like to consider this:

It works out at around £360 inc shipping. Considering the cheapest chart plotter in the UK is £343 I think it is a good deal. Don't forget to add your charts!

Eagle is Lowrance's budget brand.
PM me if you want contact details of the supplier I used.
