spyder 2000 with a boo yaah elcd, dye ss barrell, exp chamber, lots of other stuff.
it makes a spyder fully auto matic that alone is worth it enough. it has full auto, burst fire 2-10 round burst modes, regular semi mode, turbo mode, and safe. plus it has a tournament lock on the circute board and the rate of fire can be adjusted rom 5 to 15 balls a second. you can also adjust the trigger pull. it has a countdown or up game timer and a shot counter
and the whole thing runs on a 9 volt battery. its very easy to learn how to use even with out the instructions.
i have the original boo yaah version i dont no about the mako 1 but mine came with a car gharger. it is kind of a pain to have to plug it into my car the night b4 a game but its ok. it would b nice to have the wall charger.
very nice definately a good upgrade. ive had mine for a month and have not had any real problems with it. if you play around with it you can get your spyder to do 15 b/p/s with no chops. you can probably out shoot cockers, shockers, impulses mags u name it!
