photohiker wrote:I have always used the tracking feature. It costs $50 a year and friends and family can watch progress. If your OK message fails to get out, they can still see where you are and if you are moving, so the odd lost message doesn't raise stress. In your situation with the lost device, the tracking would either have stopped completely or stayed in the same spot. It might not have eased concerns, but it does at least give a point to start searching.

I always leave an itinerary stating what time I will be out of the bush etc and just treat the spot message feature as a bonus for letting people know I'm fine and the link to a location. If they don't hear from me assume I'm fine.
If I'm late by more than 24 hours and you haven't heard from the spot in a few days, Yeh then call S&R.

tastrax wrote:This is something that Parks have struggled with over many years especially with out duty of care to staff. We now use multiple devices to give us options on contacting staff whilst in the field. Staff will generally carry at least two devices from the following range.
- Spot
- Spot with Tracking
- PLB
- VHF Parks radio
- Satphone
- Mobile Phone
In the past they may have only carried a single device.
It also depends on the area in which they are working (remote or on a established track, radio/mobile communications available or not) and if they are walking with others. In general solo remote walking does not occur for greater than a couple of days and will depend very much on the ability of the individual staff member.
Like you, we generally have required check in times and a period after which we will commence initiation of a "rescue", however it will generally be after attempts have been made to contact the staff member via the alternate means (phone, radio or satphone). All this is documented, along with an itinerary and signed by staff prior to the trip.
Has this system failed in the past? - YES and it has cost us helicopter time to find the staff members involved but that is a cost we bear as we know that all systems can fail. Most failures occurred using just single systems. Thankfully it doesn't happen very often and we learn from each "rescue".

The issue I had is that the SPOT device was ripped out of the carry case that comes with it. I don't recall there being any clipping points on the SPOT itself. In future, I would be inclined to store the SPOT inside my pack.

Mark F wrote:I have been happy with my Spot 2. I have lost 1 OK message out of about 200 sent and that was in the bottom of a heavily vegetated steep sided valley. The GPS positions have always been accurate. I keep my Spot in the top pocket of my pack so it easy to get at. When not walking it is in my car should I be involved in, or come across, an accident on a remote road. I always carry a spare set of batteries on long trips or rely on the fresh batteries in my GPS and head torch. The Spot 2 will run on NiMH batteries in a pinch according a review on BPL.
My protocol with "Dear Leader" is one OK message a day in the evening. I also send an OK message at the start of my walk and when I get to the end of my trip. Raise the alarm ONLY if I have not been in contact (Spot message or phone) 24 hours after expected return.
If I am going to be late but am OK I send a Custom Message for each day I am likely to be delayed.
If I send a Help/Assist message it means that I need to be picked up somewhere other than my intended destination and to watch my OK messages until I hit a public road. If I am at my expected exit point (an OK message should have been sent) or on the road out then it means I need mechanical assistance with the vehicle.
If I need rescue I will hit the SOS button.
I think a lot of the reported problems are to do with people not letting the message sending process complete - it takes 20 minutes - poor choice of sending location and past issues with the satellite constellation.

I don't understand how your belief could have any exeriential basis, really.

Yeah, I wore mine on my shoulder harness, similarly.
Well, according to an EE mate of mine the GPS receiver can cause interference in other (improperly shielded) receivers. I presumed it had something to do with superhet mixing they do to extract the IF from the signal. So that's an idea of how it could be interfering, etc.

Oh, I dunno ... nothing says "I am not paying you any more money" like cancelling the CC.
photohiker wrote:In discussing issues people have with the spot with those very same people, both personally and online. I have found that at the most extreme case they did not read the manual, thought they could just turn it on, push the ok button, wait a minute and turn it off. There are plenty of failure modes that can be introduced by the user that will make any shortcomings of the device irrelevant.

Sure, you are delivering a message to them, no problem with that. The message is: I'm going into default on the contract I agreed to. Bite me!
Hopefully, they will just let you off. Like I said, good luck with it.
wayno wrote:my understanding is the satellites used with spots arent as numerous as the ones used for PLB's
i read somwhere they have an orbit lower on the horizon down under.
photohiker wrote:wayno, that is correct. The Spot uses a different sat network to PLB's.
Colinm, are you talking about a Spot1 or a Spot2?
Spot 2 came out in late 2009, and was almost immediately subject to a recall due to battery consumption issues. Replacement units did not appear in the US until around March 2010 and Australian Stock was in limited supply from about April 2010 as they were flat out dealing with warranty replacements. I managed to import one of the re-engineered from the US in April 2010 (I had a long distance walk coming up in May so I couldn't wait for AU stock). Your $300 arrears suggests 2 years service after your first year - that last $150 wouldn't be due yet by my reckoning if it was a Spot2?
