Hema HN5I vs HN6

Good morning all. I would like to hear from people who have experience with either of these two GPS's. Apart from the screen size & cost, what are the main advantages & disadvantages when comparing these two units. Cheers.

Thankyou, Yes I have seen that, but don't fully understand the "Preloaded raster mapping".

Hi Allan,

Preloaded raster maps are just electronic maps made from a photocopy of a paper map. When you enlarge, the image gets bigger but no more detail shows. The HN6 has all of Hema's detailed outback maps, about 80 in all, preloaded. You can use Aust Topo 250 to get to a remote area then press a button and select the very detailed map of the Park of where ever you are.

Hope this helps.

Greg.

Hi

Just to clarify "raster" simply refers to the image format ..in this case being made up of thousands of colour pixels, same as a digital photograph. These days it is possible to create and save a map in raster format without the need to first create a paper version and then scan ("photocopy") it. You only need to scan a paper map if data required to make the map is not available in some sort of digital format i.e. only paper version available.

The raster maps supplied standard on the Hema 6 are not scans (photocopies) of paper maps...they are direct conversions to raster format from original digital data. Other commercially available maps that will work on the Hema are however scans of papers maps that have been saved in raster format eg 50K Kimberley/Pilbara raster maps available in the ExplorOz shop.

This is in contrast to "vector" maps which are created on the fly by the GPS/Computer from a database of points (with geographic coords). The points are shown as locations (i.e a single point), road/rivers (i.e series of points joined to make a line) and areas (ie points joined to form a polygon). IGo on the Hema uses this format as do all other street navigation programs.

Cheers

Hi Allan

I can only comment on the original HN5 v the new HN6

There are a few differences between the two, some good, some OK.

Firstly the screen size does make the biggest difference and if you are looking at buying one, pay the extra and go for the 6" screen and you will not regret the purchase.

My original HN5
Screen size 5", still good.
Maps very good, complete with the original Natmap 250K of Australia, but broken up into zones due to the full version being over 8gb in size. I tried to add the one complete Natmap to the Maps folder, but being over 8gb, the unit would not read the maps.
Still very user friends and a very reliable unit for me, that I still keep for the 'just in case' situation. The biggest downside was in my opinion the Route 66, which Hema did see the light in the end and gave it the big flick.

My new HN6
The bigger screen size is great and it did take a little getting use to the new layout.
The first biggest thing that I personally do not like is that Hema have gone away from the Natmap 1:250 Map zoned areas and instead have made their own. Hema claim that is has the same detail, but I personally do not agree and have loaded the old Natmap's series of zoned maps into the new HN6 and use them instead. They now use iGo for street navigation which is fare better that the old Route 66.

I have found a few sections when for some reason, sections of road are complexly missing on their 1:250, but are in full on the Natmap series.





The new HN6 now has the ability to load saved tracks and waypoints easier compared to the old HN5, a new feature that I really like. The old way you would have to open folders, add waypoints or track and then they would be able to be used when required. The new way is just like using OziExplorer, send selected tracks and waypoints on the map direct to your HN6 and it is that easy.

Either way they are great units and are perfect for where I use mine, out in the bush.


Have a Great Christmas.



Cheers

Hi Allan
I use the HN5i (originally a HN5 that was upgraded by Hema to an HN5i). Firstly the on road mapping is very good, easy to use and search and a big improvement on previous versions.

Most of the time though I use it for off road travel (Ozi Explorer) and use it for plotting and planning routes through the bush and then navigating along them.

I've always found it very reliable and while Ozi Explorer is fairly complex you get used to it after a while.

I would definitely go for the larger screen - especially as my eyes aren't getting any better and when you're bumping along a bush track it can be a bit hard to click on the right button!

Highly recommend the Hema Navigators - I had the original and they just keep getting better.

do you already have ozi explorer compatible maps? or can you get some of friends?
if so the cheapest option is to get a 7 inch navigator from ebay and install ozi CE onto it and the maps onto an 8 gig card (make sure you get a navigator that takes 8 gig cards, some just take 4 gig)

I recently did this so for $120 ive got a navigator that does street nav using IGO8 and off road mapping using ozi explorer and an 8 gig card for $120

well why would you buy new maps every time you get a new device?

I run my maps on my laptop, my phone and on my navigator - explain why you wouldnt ?

..? Come on Dave - Why are you suggesting someone get maps they don’t have off a friend? That was my point. Nothing about re-purchasing maps they already own. Depends what maps you are talking about of course ...some are free game.

Would be interested to see if you are brave enough to name the maps you hand out to your friends. Look forward to your reponse:)

Cheers

No problems. They don't actually have a name because there not commercially available.
There known as C.A.L.M maps and I guess we're originally produced for them. They are 50 k maps but are a lot more detailed than the commercially available 50k maps and are my first choice when travelling the Sw.............
Any other questions?

mmm nice try...but they are commercially available just not specifically advertised anywhere - cost a fortune (~$500 per set), you have to contact DEC mapping/GIS department I think, from memory. Referred to as CALM Operational Graphics (COG), also available in booklet form or map by map. Apart from DEC inhouse use also used by SES, FESA etc. I am also aware of a few environmental consultancies which have purchased a licence to use them.

They are sold under very strict copyright (you have to sign a form acknowledging copyright (which among other things forbids “sharing” the maps)...do you remember that bit? :) Because of the high cost, not surprisingly, lots of people steal copies.

Bottom line - I wouldn’t be publically promoting the piracy of these maps (or any other maps you have but failed to mention that have copyright) on this forum…thats all, nothing else....but that’s just my opinion.

Cheers

All I'll say is he who is without sin may cast the first stone

I'll freely admit I've got plenty of maps. Some paid for some not
I'VE recently spend close to $200 on maps

You missed my point again...I don’t publically suggest people should “share” copyrighted maps (as you seem to have done). In this respect I am a Saint :) That’s is my advice to you (and others). With all due respect I dont care what maps you have or how you got them. What you do behind closed doors is your business.
