Ventajas
Experience that you cannot get anywhere else. You get to break all the FARs you ever wanted to legally... You get to hear the coast guard helicopters try to bust you with ATC for low level over the metro area. Night vision goggles are a plus.
Desventajas
25.5k a year as an FO to fly with 200 gallons of economic poison three feet from you at 100-300 feet off the ground. Upgrade takes about a year. Amounted about 500 hours a year of flight time with about 50 hr of it counting toward FAA spray PIC over congested areas. The amount of money for the risk doesnt really make sense at the end of the day. On call every day. Middle management doesn't know what their managers do to control costs, IE cut benefits for Pilots. Maintenance is also sometimes sketchy, but most of the time is good.
