Good news and bad news about SPOT 2 devices

My SPOT1 batteries need replacement after more than a year (over 300
hours). So even if SPOT2 needs more frequent battery replacement it
may not be a real issue for most pilots.

Are you using the "replacement" or the "original" Spot 2?

One of the reasons for the replacement program was power consumption.
I have a replacement unit, but I haven't used it yet. Just curious.

To be anal-retentive clear on this, I don't believe that the issue was
power consumption per se, but rather an incorrect low battery warning
so people would be lead to change batteries earlier than necessary.
AFAIK there was no mod to improve actual battery consumption (just the
apparent consumption). See for example Doug Ritter's comments at

If somebody knows for sure else wise speak up...

It is a pity with the SPOT 2 that the hiker/general user etc. goal of
making the device smaller overrode long tracking battery life. I've
still got the original SPOT and never really had significant dropped
tracking message problems and am not sure I'll upgrade.

Hmm, I have no direct experimental evidence regarding SPOT 2 battery
life. However, Fernando Silva had a new one at Perry, and he had to
replace the batteries after just a few days. The SPOT website quotes a
battery life of between 3.5 and 7 days in tracking mode, and the SPOT
customer service representative I spoke to acknowledged that the SPOT
2 devices do have shorter battery life 'due to the stronger
antenna' (which I interpret as higher transmit power).

I am sticking with my old SPOT 1clunker - I know how to get it into
track mode reliably, and I only have to change out batteries once or
twice per soaring season ;-).
