Hey guys,
Originally MOBALL came about because I didn't feel there were enough portable ballistics computers that work with G7 BC's. With all things there are pros and cons. Here's my no BS run-down of the pros and cons of MOBALL compared to other mobile ballistics devices.
Pros:
1) Size. Large easy to operate buttons and easy to see screen. If you've ever used a toothpick to push the little buttons on a smartphone or tiny touch-screen you'll appreciate this.
2) The TI-Voyage is not a network device like an iPhone or smart phone. Benefit here is it's not intended to work with a data plan/subscription meaning no commitment to recurring fees.
3) Batteries. It will run for months on 4 regular AAA batts. No fancy expensive rechargeable deal that you need another plug for (pet peeve of mine).
4) Features. In addition to the regular variables required for basic solutions, MOBALL also has the option to account for spin drift, coriolis, and multiple winds in up to 3 zones.
5) Accuracy. The MOBALL solution compares well with JBM and other 'properly written' ballistics solvers. See the accuracy report.
6) Versatility. The device isn't networked, but it's still very useful as a calculator especially if you're a highschool or college student in math/science classes. The TI-Voyage is an impressive tool even without MOBALL.
7) Support. Upgrades and bug fixes are made available to past/existing MOBALL users. Updates are sent out via email and there are clear instructions for the user on how to install the upgrade. I'm available to answer questions and assist/troubleshoot any problems.
Cons:
1) Size. Although its size makes for easier operation, MOBALL is larger (more to carry) than most portable PDA/cell phone devices.
2) There is no library feature that includes BC's for a list of bullets; you have to find out and enter the BC of your bullet.
3) You can't save a 'set' of inputs. Some programs allow you to save a set of inputs that's unique for different rifles. MOBALL doesn't have this capability.
4) MOBALL doesn't output tables, only a single firing solution (windage and elevation) for a particular shot. That's what it's designed for. Running tables is homework for a PC IMO.
5) Durability. The unit isn't fragile; it's as durable as any normal electronic device (think cell phone, walkie talkie, GPS, etc) but it's not waterproof. It was made for a classroom/backpack/school bus environment so it's tough but don't drop it down a rock cliff into a frozen river and expect it to work like some of the 'ruggedized' mil spec PDA's out there.
6) Cost. You can get away with a handheld ballistics computer for less money if you just want a basic, ballpark solution or if you already have a iPhone you can get several good programs on it inexpensively. But if you need a very accurate and complete solution, and you don't already have an iPhone (and/or don't want to change your phone service provider) then this is a very reasonable option.
