Newbie here! Pump or battery?

I'm new to prospecting/fossicking and have just purchased a high-banker which has 1 inch fittings to the spray bars.My question is, can a 1 inch petrol water-pump be enough to run it for a recirculation set up? I've seen the perfect pump($200) that weighs only 5.3 kilos,though I've never used a pump before so I wouldn't know how to treat it right or maintain it properly or is a 3-5 amp bilge pump 3.500 with a 105 amp rechargeable battery easier? Bottom tray is 700mm long 250mm wide.I will be trying to focus mainly on dry area's with recirculation as there tends to be no one around which I like. I guess my main issue is I don't understand yet the kind of water-flow I'll need with this high-banker and no idea how much and how fast the water transfers from the pump to the Hb or from bilge/batt to Hb.

The problem with bilge pumps is no umph,
they can't lift more than a meterísh without losing rated flows, friction severely limits the length they will pump??
However, like your saying your gonna work dry areas, means your carting water to the sluice?
if you can make it work at home, you'l be fine in the field

hmm thx good to know about that metre issue thx,so pump it is then,is the 1 inch pump enough water flow for the high-banker? And yes I will be carting water out to the spots.

I'm thinking to buy the 4 stroke Honda 1" but not sure if its enough water flow with the 1".The place I bought the high-banker recommends 2.5p 1.5" hope someone has some experience with this issue to advise me on. http://www.aussiepumps.com.au/PDF/specSheets/pumps/Products_pumps_QP%20pumps_1_Aussie%20Ultalite%20pumps.pdf
