Bravo pressure gauge questions

Bought a Bravo pressure gauge to use on my Zodiac classic with semi recessed valves. Never used a pressure gauge before. Put the valve adaptor on it and then put the hose on the topside of the gauge. I have a Bravo 5 footpump and when the gauge shows 2 psi it is really hard to pump.
I normally just pump it up without a gauge and when the tubes feel tight stop pumping. But the pump never gets difficult to pump.
So have I been under inflating without using a gauge or has the gauge given me a false reading.

I had the same issue you did last year with my MK2 GR as well. I had been using foot pump to get the tubes tight, then i would stop.
I bought a gauge and thought for sure it was broken, because it was showing 1.5 ish psi even though the tubes were pretty tight.

I then bought a bravo 12v pump and dialed in the psi to 3.4 and oh wow.. I wasn't even close to getting the tubes to the correct psi. The gauge also read the correct psi suddenly.
I learned that the foot pump really is useless as it would take so much effort (and weight) to get to 3.4 psi.

Hope this helps.

I would suspect brveagle is correct.

cheers for that info......certainly sounds like I've been under inflating yet the boat seems ok. Looks like I will have to get a power pump instead.

I second that. I have mk2 future. The foot pump needs a younger man than I am. The electric pump with shutoff is the way to go.
Also once you launch the inflatable keel cools and I top it off since the keel is what tightens the bottom fabric.
