Hello All
Yes. Actually the device hardware is made in Taiwan by a company called Sanav. The real name is ML-7 (for every second log) and ML7-S ( for 3 minute logs) . Both GEM and PATHFINDER take these devices, add thier own software and harness and sell it on. I sell the bare 3-minute devices for £55 on ebay. It comes with standard software (not the fancy stuff) but you do get google map tracks with the standard software in a basic way. For a small charge of £20 I can change the device to any time interval from 1 minute to 5 minutes and more (but who would want more?) . Plus I can also convert this to a fully waterproof version with magnetic switch and epoxy potting for another £50. I am now investigating on making them solar rechargable for longer life (using the best solar cell available commercially) This will decrease the logger weight by another 3-4 grams because then we can use a smaller battery.
