You might have picked up that I am doing some walking in Scotland this year, and I've been beavering away to get ready - I've got to do all my own planning including route, stops, food and gear (and travel) for a 2 week ~300km walk across the highlands. One of the things on my to do list is to sort out what GPS and mapping I will be taking with me. That investigation has led me to the conclusion that if I want to have good UK mapping on my GPS, my current Vista Hcx won't cut it. You can get good mapping for more recent Garmins though - the Oregon and the Dakota. Whilst checking these out, I came across another brand that looks to be gaining traction with hikers (hillwalkers) in the UK:
The SatMap 'Active 10'The unit itself is a toughened case, weather resistant PDA style gadget sporting a 3.5" screen and good, current GPS hardware (Sirfstar III) It has been designed from the ground up as an off-road sports GPS, no on road auto-routing capability is present. Battery options include AA or lithium polymer 2700mAh powerpack, as well as 12v/240v. Users are reporting several trail-days battery life out of the LiPol battery. Weight is 175g + batteries. The unit has been on the market for around 3 years and the software and hardware appears to be stable. The manufacturer offers hardware upgrades and repairs for older units that may have had an accident or that need hardware features that have been added to more current models. The front screen is replaceable, so when you scratch it, you can order a new screen and make it like new again. The 'plus' model which comes with the LiPol battery option costs UKP378 ($660) which is in the ballpark of the higher spec Garmins.
Of course, hardware is no good if it doesn't have decent mapping, and this is something of a 2-edged sword in the UK, because they have excellent state-controlled mapping which is available for the SatMap in 1:25k and 1:50k (for the whole country) which by all accounts works brilliantly. It also costs a lot. For instance the whole of the UK at 1:50k costs about UKP200.00 ($350) I haven't looked what the whole of the UK at 25k:1 is, but it would be a lot... Better to just buy what you really need I guess. One of the interesting map options for me is the custom trail maps. You can send in a GPX of your intended route and they will cut a stripmap for the Active 10, 6km wide at 1:25k and 12km wide 1:50k. Costs are far more reasonable, 300km costs UKP78.00 They also offer a custom map service where you send in your map data and they will activate it for your Active 10 - you cannot add non-SatMap maps to the unit yourself.
Prices here are list, and include VAT. My experience is that you can get the VAT off stuff from the UK, and it usually costs about the same as the freight. You can also often do better than list if you keep your eyes open.
On the whole, it appears to have an interesting feature set, and offers a pretty good alternative to the other players in the market. I'm especially impressed with the repair upgrade options, and the availability of custom options with mapping. I've ordered one to try out. If it goes well, I will take it to Scotland, after that depending on how well it performs I may keep it and put Aussie mapping on it, or sell it on ebay.uk.
And yes, I will still be taking paper maps and compass with me to Scotland...
