Confused on rod power by numbers

[GoneFishingLTN]

So I'm looking at a cranking rod with moderate action but it's rated as a 5 power does that roughly mean mh?

There is no standard for rod ratings.  Tell us what rod you are looking at and advise can be offered.

5 power usually means HEAVY- A rod that could be used for deeper diving crankbaits.

Is that 5 gm or 5 mg?...

good luck. no standardization. i have the same trouble and have been looking for a cranking rod for big baits for weeks. problem is no local shops have anything suitable and i dont know what im getting on line. oh and i dont want an 8 foot one.

Not much you cant do with a 7MH or 7M. I wouldn't buy a rod with a number as the action.

I believe that "5 power" is an older power designation that does indicate pretty heavy power, although I don't know if it's based on actual measurements or on opinions, as most power ratings (M-H-MH-H) are.  Not every brand's H is the same power.

 

The only objective power rating system is CCS, I believe.  https://www.common-cents.info/

 

It measures the weight that it takes to deflect the blank/rod to 1/3 its length.  Many of us builders use it to select blanks to build that meet our power (and action) requirements, once we have become familiar with it and many of the popular blanks.  A few blank manufacturers are starting to publish the CCS numbers for their blanks, Point Blank, Rainshadow Eternity RX10, and NFC to name the ones I know about.  I have never seen a CCS rating published by a rod manufacturer.  

 

CCS measures power and action objectively, but does not measure anything relative to sensitivity or response/recovery time.  But I have a simple, inexpensive,  process for that, if anyone is interested in measuring recovery time, true natural frequency (TNF)..  PM me for a tutorial.  (It requires an Android phone/Kindle/tablet + a free app).

This number is a power description, not an action description.  But whether power (L-M-H etc) or action (slow-moderate-fast-etc), they are very imprecise with not all makers rating the blanks/rods the same.   A recent example on another forum has a blank described as M, MH, and H by 3 different people.

True Natural Frequency made my life force crystal giggle, or maybe it's sympathetic oscillation, what's next? the Lowrance transformation?....

Glad you got some humor in your life.  Besides being humerous, it allows one to determine objectively whether or not his premium dollars are yielding any value.  How do you accomplish that now?  Advertising copy?

No, collecting purchase data and ignoring customer surveys, in the old days it required real work and time, today the algorithms do it almost real time, what's more, they create the feed back loop that feeds on it self. The only hard part is not spilling all the m&ms all over the baby carriages...

Sounds a lot like a Lorentz transformation.  Not sure  what a Lowrance transformation is.  Seriously, if you aren't interested forget it.  If what you have works, fine.

It does, I Fibonacci space the guides...

Which rod/brand are you talking about?

If its Falcon, then that's a medium heavy which fishes on the lighter side of Medium heavy compared to others.  Not quite as light as a true 'medium' in other brands, but not as heavy as a MH.

What lures are you planning to use?

5 power crank bait rods are moderate action, slower upper 1/3rd of the rod  designed for crank baits 1/2 to 3/4 oz, medium-deep divers rated 1/4-3/4 oz lures.

For example Dobyns MH, 705 series crank bait rods.
