Congratulations on your new purchases. They are both wonderful tools. Isn't the handle of the Mk3 really cool looking? The knife is much heftier than some might expect.
As with all of Doug's knives, make sure you sharpen them at 15 degrees to keep the original angle. I highly recommend the Spyderco Shaprmaker, if you don't already have one.
Though you may not need it, you may have already noted that the GPS connector that comes with the AeroFix has bare wire ends. If you want to purchase the one with the serial connector, contact Sandy at ACR Electronics, (954)981-3333 EXT 2110, [email]sgopie@acrelectronics.com.[/email] The serial connector is part #9391 and costs $37.00 plus shipping. I e-mailed the details of the order to her and the ncalled her with my VISA card number (I didn't want to e-mail a credit card number).
At some point I might find a local store with Otterboxes and find one that fits well.
