Desert notes, from the spec sheets only. Iridium does not need a cell tower. Heat ceilings sit at about 60°C across the set. Mini 3 publishes IP67 dust protection. Messenger Plus and 67i do not. Battery numbers assume a full sky.
Will they last. One-year limited. Repair or replace. Authorized US reseller. You pay freight.
Can they be fixed. Through Garmin, with a receipt, inside that year. Damage from unauthorized service isn’t covered.
What it costs to own per year. A subscription. Live rates are not listed here.
Worth it if you leave coverage on purpose. Skip it if you want SOS without a plan. That product is not in this log.
Nikon PROSTAFF P7 8x30 is the glass. Casio W-221H is the backup clock.
