Ok thanks Doug, I think sometimes it's worth paying a little more like ACR to get a solid performing device, I know company's work hard to get bugs worked out of earlier failures and sometimes end up with products more superior than others, but I don't think this will be the case with this manufacture, I think Spot has the best chance of getting into this market with a new model that has a user replaceable over the shelf battery, works dual mode with the COSPAS-SARSAT satellite system and 121.5 MHz frequency for free and then have the option to pay if you want for the other services. Plus it would be nice if they incorporate a external power plug in to use solar cells or a vehicle battery if a battery failure or a long rescue attempt is needed due to weather restraints or what have you. I know most of the gear I carry can run 100% off of a 40 watt foldable solar cell with no batteries needed and it's a nice feeling for a back up with solar cells when traveling.
