Davis Vantage Pro 2 model 6152.
« on: November 12, 2007, 10:07:34 AM »
Hi,
This is my first post.
I live in Queensland, Australia and am planning to buy my first weather station, a vantage pro 2 wireless.
Perhaps someone can answer this question for me please. If I buy my station from an American retailer
will it be suitable to use straight from the box in Australia or will the wireless bandwidth or anything else be a problem.
Suppliers from America sell the units for around US$400 and the Australian pricing is around A$1200, to me
an extreme variation.  Any comments re pitfalls I may encounter would be appreciated.

David.

David I think you could run into a problem with the radio frequency used, the US frequencies are not legal in many countries. Here in the UK for example it is illegal to use a US station and can result in confiscation if detected. I believe it may be the same in Australia. We have the same pricing issues here as well :( :(

Frequencies for the US units and frequencies for the Australian units are different.  I cant recall, but I think the US units operate on frequencies in Australia reserved for mobile phone carriers.

The frequency band for the VP2 in the US is slightly different from the EU version. US: 916,5 MHz vs EU: 868,35 MHz.
This relates to the frequency bands used for GSM that are different in the US and EU.
GSM in Europe (as well as Australia) uses the 900 and 1.800 MHz bands and those are off-limits for common citizens. GSM in the USA operates in the 800, 850 and 1.900 MHz bands. APMS (analog) in the US uses 800 MHz.

Buy the 6152C wired version, not quite so convenient but it will work legally anywhere.

Thanks for responses.

I guess the next question is can a US sourced 6152 have its radio frequency easily/cost effectively changed to the  frequency of TE923W or WMR968 or similar. I appreciate that if it is possible that it would have warranty implications with Davis but as the units are supposedly so trouble free warranty would not be a large issue.

I think the OZ distributor may change the freq of the units they import and sell, but they aren't likely to do it cost effectively for you. I doubt it's possible for anyone to do it without access to Davis proprietary info.

It got me baffled why the AU and EU version need to be so expensive, all what is different is the frequency.

The frequency will be interesting as NextG sits in the range area of the AU and EU version. NextG is the "competitor" of GSM.

I run a VP1 since 2002 without a problem, I know the ISS board has a bug but that does not worry me to much. It is a wireless, I like to go VP2 with solar and uv but cannot justify the price difference.

I am hinting towards the US version but I am not brave enough as yet, I might do it one day just to protest against the price difference. Honest it is almost double the price here than it is in the US, why?????

My station is based in Dayboro (www. dayboro.info or www.lyndhurst-hill.info) that is in QLD if you are in the area feel free to drop in for a cuppa and I show you how things can work (and do not work :-)).

It's not technical, it's just business. I think the biggest factor is that there's an exclusive distributor arrangement instead of everybody and his brother buying direct from Davis and selling competitively at a low margin - while relying on Davis USA to do all the support. Then there's some unavoidable extra costs like import taxes, and sales taxes which are generally higher than in the US (some US states do have a sales tax, but US prices are always quoted before any sales tax), and the higher cost of employing staff outside the US.

That's pretty much it in a nutshell, though there are one or two further factors. The cost of shipping stations by airfreight around the world is nontrivial. And the other key aspect is providing local warranty and support, which Niko mentioned but I'd underline because it is a very significant expense for local distributors and one which is not refunded by Davis AFAIK. Also in this context there may be a longer warranty, eg here in the UK all 'official' Davis supply has a full two-year warranty. Finally there's the issue of local market size. If you're a local country dealer selling maybe 30 or even 100 stations a year then you're just not able to operate with the same economies of scale as people like Ambient or ProVantage who I'd guess are doing 500+ units per year (and scarcely having to even consider after-sales support once the box has shipped).

But having said all this, if Davis could be persuaded to relax their veto on supplying local dealers direct (ie direct from Davis) raher than via a monopoly trade importer in many countries then you would I'm sure find retail prices very significantly lower in export countries.

For sure davis will have warranty and if the unit is broken than they will replace it.
Shipping cost is 9 out of 10 times paid for by the end user anyway.
I assume that dealers do not only sell davis, for sure they have a wider range of products.

Let me clarify: Yes - Davis will ultimately replace faulty hardware if under warranty (but only for one year), but the local dealer will have two sources of additional expense. First there's the staff cost of dealing with the support incident. If you've ever run a business you'll know that the overall cost that has to be allocated against staff time is very significant, say $100 an hour even for a small business. So for an incident that might take an hour all-told to deal with (time on the phone/email - often repeatedly and often 'false alarms' when there's no actual fault, actually dealing with a physical return and then shipping out a replacement) it's easy to rack up a $100 cost on a single incident. Second there's the cost of holding extra inventory to provide replacement parts plus the cost of shipping out replacements & returns to Davis. I know you might not want to believe this but in the real world all these costs do add up.

Well in one sense that's true - all costs ultimately have to be covered by the end user or the business goes bust. But the costs of shipping stock around the world are quite significantly higher than eg within the US.

Yes but the same argument applies to the other products too. A dealer for weather station products in the US will have a potential market of 300 million people or thereabouts and with one of the highest disposable incomes in the world. Other dealers in individual countries will have a fraction of that market size, typically with a lower disposable per capita income.

We are drifting way off topic here and know that Prodata has some very valid points for the UK, as dealers can only source supplies from the Official UK Importer.  However, I believe that it is the cosy arrangements made by overseas manufacturers and Official importers, to attempt to stifle direct retail sales from overseas to the UK, that is compounding the problem.  This does not just apply to Wx Stns but a whole host of other products as well.  The same cosy arrangements seem to exist in just about all other overses markets.  Usually, it is the product "guarantee" that is not upheld, or made extremely difficult in some way or other.  This topic is endless :( :( :( ....

This subject came up on another forum, as did that of the warranty of units bought from overseas.
Does anyone know if the warranty for an overseas unit will be valid in another country or does then unit have to be sent back to the original supplyer for warranty work to be done?
