Yeah, but I watched other vids and when they are pumping the gauge isn't going into the red then dropping down to where the green line starts.Pumps are hard when you hit high pressures.
Seriously fella - a decent tank is going to set you back only a few $ (in the UK perhaps 200) and as long as it is in test then a refill at the scuba shop should be the price of a decent coffee.
What you are struggling with is a crap rifle. Move it on and get something worth investing time in. Or better yet go back to Dick’s and ask for a refund as it doesn’t work.
