Les,
Thanks for the good info Les,
Oh! I'm tempted now.

Very early SATMAP units took an age to fix on the Satellites. I actually rang the helpline one morning from the Pennines as it hadn't acquired a fix in over a quarter of an hour.

Shortly afterwards a patch was sent to all users which solved this problem and now,like Les, I switch it on upon arrival and well before I have my boots on and my gear packed it is all up and running.

With the power bundle I have used it for 2 full days away and still had the maximum number of charge bars showing. I do,however, carry a set of their own rechargeable batteries if I am out under severe weather conditions or in a remote area.

I bought a site-centred map based on the Tebay service station. This gives me coverage of all but the far western lakes, all the Pennines as far as Hadrian's Wall and a lot of southern Yorkshire. Expensive,but for me, worth it for the. convenience.

I have also picked up boxed SD cards for Derbyshire and Northumberland at £10 on Ebay. I checked before I bought them that they came with a SATMAP box

I confess I do not use it to plan routes by plotting waymarks as it is not the type of walking that I personally do. I can see how the yellow line would be annoying to those that do.

Thanks SC, food for thought.
Dave.

Think I'll stick to the good old map and compass myself. All that sounds like a fair bit of extra weight and expense, and I don't feel comfortable trusting my navigation to an electronic device for various reasons.

Each to his/her own. The calibrations on my sextant are becoming increasingly difficult to read now though.
