Official GHB/BOB rating scale (LONG)

Discussion in 'Survival/Preparedness Forum' started by WilyCoyote, Jan 18, 2008.

  1. It's funny to see so many people having trouble with not looking at it as a grade scale. Since there are so many variables, as well as what someone's idea of a GHB/BOB actually is, the scale was designed to compare apples to oranges. I tried to make it so people could see if they were apple people, orange, or bananna people, if you will. A 70 is not better than a 50, it's just different.

    I sacraficed in several categories for portability and ease of storage. ie, a two man tent is nice, but I can hack it with a fleece pullover and a poncho.

    Also, I recognize the importance of fire, maps, etc, but in order to include those categories, I would have to dillute the value of the others to less than a 5% varibale. I thought that would make things too vague for comparison. It seems it would be very easy to overcomplicate this scale.

    I do see your point Wily. For starters a GHB and BOB (while conceptually similar) are very different things and would score differently on these scales. For instance, a GHB needs only a day or two of high energy snack food whereas a BOB should have regular meals for at least several days if not a week or more.

    Also, people face different problems in their planning and that would also effect how a bag scores. If you're in a cold weather environment then you need a sleeping bag, bivy and a tent. For warm weather, sleeping out under the stars might be perfectly reasonable with only a poncho to keep the rain off.

    As for the actual scales, the rule of threes should reign supreme. Shelter, water, food in that order. However, I think there might still be room for some additions here. Fire making could be incorporated somehow under shelter because the main purpose of a campfire is to defend against exposure (but can also cook food or sterilize water). I'd also like to propose the following three scales be added to the overall system.

    First Aid:
    1. Rub some dirt on it, it'll be fine.
    2. Barney print boo-boo kit.
    3. Aspirin or acetaminophen, antihistamine, assorted band-aids
    4. Pre-made hiker's first aid kit (Ozark Trail, Coleman, etc.)
    5. Pre-made hiker's kit with useful additions such as moleskin for foot blisters, sterile pads and butterfly bandages
    6. First aid kit above plus needed prescription meds.
    7. First aid kit above plus prescription meds and personal medical info (blood type, allergies, conditions, etc.)
    8. First aid kit above plus a G.I. bandage.
    9. Clotting agent, pressure and triangular bandages for traumatic injuries
    10. Surgical kit or M3 Medic bag with scalpel, suture, disinfectant, antibiotics, clotting agent, etc.

    1. HELLO! Hello... hello...
    2. Signal mirror and flashlight or light sticks
    3. Signal mirror, flashlight and handheld flares.
    4. Signal mirror and hand launch flares or flare gun
    5. Strobe light beacon and/or portable FM/AM radio
    6. Shortwave radio receiver and some form of the above.
    7. Multiband receiver and/or handheld walkie-talkie under 5 watts (e.g. FRS/GMRS)
    8. Handheld/portable single-band transceiver at 5 watts or more (Ham VHF/UHF or CB).
    9. Ham radio handheld/portable transceiver with wide band receive and multi-band transmit at 5 watts or more.
    10. Radio bag with antennas capable of wide band receive and multi-band transmit at 40 watts or more.

    1. Where am I and what am I doing in this hand basket?
    2. Which way is the sun?
    3. Map? What map? I don't need no stinking map. I've got a keychain compass and the map is in my head.
    4. Rand McNally is my friend.
    5. Laminated street maps and decent quality compass.
    6. Laminated street maps with lensatic compass with preplanned route.
    7. Lensatic compass and topo maps with pre-planned route.
    8. Lensatic compass and topo maps with primary and alternative routes that avoid congested/ problem areas.
    9. GPS receiver with typical street maps.
    10. GPS receiver with detailed maps in memory of my AO and pre-plotted primary and alternative routes.

    How much these should be weighted in the overall system is up for debate. I'm thinking no more than 5% or 10% each. Where that weight should come from is also negotiable. I won't add these to the spreadsheet unless the group consensus is that they belong (and at what weight). I submit them to the group for discussion.

    P.S. I smell a sticky here...

  3. I like those scales and I also like how you incoported fire and light into shelter and communication, should make things easier. I agree that the main scale should be modified, but there should be some agreement as to the defenition that matches both the BOB and GHB, since some choose one over the other based on their needs.

    How about this:

    A BOB (Bug Out Bag) or GHB (Get home bag) is defined as a person portable collection of equipment preassembled with the specific goal of assisting a person or persons with rapidly obtaining a short or long term overland goal. It's contents include equipment needed for sustaining life or otherwise assisting the user in acheiving the overland goal.

    Below is an ammended list of category values based on user suggestions. I'll go ahead and edit the list at the top, Gecko, can you edit the spreadsheet?

    Shelter-25% BASIC3
    Hydro Power-20% BASIC3
    Feedability-15% BASIC3

    Navigation 10% (Necessity to achieving overland goal)
    Portability-10% (Necessity to achieving overland goal)

    Combat-5% (Contingency, may or may not been needed)
    First Aid 5% (Contingency, may or may not been needed)
    Comms 5% (Contingency, may or may not been needed)
    Durability 5% (You aren't getting anywhere if your stuff falls apart or fails in the field)

    Awright, I'll play, but I need a little HELP in getting my base score on some of these....

    If I did it right, and based on my "best guesses" at some of these, I rank a 68 maybe?

    Open to "quibble room" on the things I'm not sure about...

    FWIW, it's for a GHB. The trip from work is only 15 miles (YAAAY!) but most of it is up and down pretty steep hills (BOO, HISS).

    I think I do pack too much stuff in there, I need to trim it down a bit.

    Anyhow, hard as it was doing it (which wasn't that bad really, even before the spreadsheet), it must have been a lot harder CREATING it! Hats off to WileyC!

    Alright, I've incorporated the above recommendations and promoted its status from "unofficial" to "semi-official".

    P.S. This really deserves to become a sticky at this point. Imagine, no more fumbling in the dark to describe your bag. Just rate it against these scales!

    Geko45, I really like the idea of combining the shelter / firemaking, but I don't know if they can even be combined. Some people might have different needs depending on location and such...

    To all: I think that we need to rethink the grading scale. Maybe 100 points for the basic three (because they are truly the most important), and then after that there could be bonus point categories? It will still be difficult to reach 100 points even with the bonus points...

    In the "basic 3", we can have a separate category for firemaking since it is vital to food, water, and shelter... so essentially they are 4 categories sharing the 100-point scale. Then as bonuses, the Navigation, Communication, and I really think we need to do something about medical / hygiene, and something about environment adaptation (such as respirators, KI tablets, gloves, etc in case of a NBC attack or situation. I think flashlights and NVG's can fit in here too since they are for adapting to a dark environment).

    That actually sounds like a pretty solid scale - making the basic 3 (in our case 4) making the 100-point scale and everything else is bonus...

    I suggest a different scale.
    If you have tested your BOB/GHB, you pass.
    If you haven't, you fail.

    This is an apples/oranges/banana thing.
    My bag is good to around 20, below that it gets cold.
    Guys in FL, your bags are setup for what 40-50s?
    Guys in AZ, how much water do you have to have?
  8. Ok I'll workout a firemaking scale tomorrow, but those points hafa come from somewhere. I'll likely have to take down the percentages in the big three down to less than a 5% variable.

    Ok, I did a spreadsheet for your rating system too, but somehow I don't think we'll have as much fun with it.

    Or maybe we will! Here's a screenshot:

  13. Ok fire making ability category has been added by popular demand and the category values have been adjusted accordingly. Geko, if you would be so kind, please update the spreadsheet. :cool:

    Done and done. We now have 10 categories of BOB/GHB rating goodness!


    Semi-Official BOB/GHB Rating System Calculator Version 2.2

    My GHB score under the new system went from a 68.5 to a 66.5 so I don't think we've skewed anything to badly with the new categories. I need to rate my BOB too at some point, but am dreading pulling everything apart for inventorying. That suckers PHAT! (figuratively and literally)

    Nah, the minimum possible score is 10. You get points for maintaining a pulse and having the ability to form words...

    i got a 59.5.

    this is pretty neat.
    if i decided to carry my 2 person tent then my score would be 72.1

    Version 2.1 I score a 62.1.

    Lowest rated or portability and navigation, each at 4.

    Just a note: It is, of course, impossible to actually score 100. You arne't going to have a rifle/shotgun, shelter, weeks worth of food, etc AND have it all fit in a pocket. :tongueout:

    But that's good. It's all about compromise. You can't bring everything with you, and the more you bring the more you get weighted down...

    Wow, this got long! Must re-calculate. V2.1

    Fire helped me out, food is still mediocre, nav sure didn't help, and neither did comms. Fortunately, as I've said before, my max hike is 5.1 miles from the horses, through sparcely populated areas, or 5.2 miles from work, through nice residential neighborhoods. That dramatically decreases my need for navigational tools, as I'm familiar enough with the area to find alternate routes, from either location, with no problems. Due to the short distances involved, this also makes my lack of gourmet food a less serious problem, and my half dozen Power/Cliff/Tiger Milk bars will suffice.

    Category Score Weight Points
    Shelter: 9 21% 18.9
    Hydro: 10 16% 16.0
    Food: 6 12% 7.2
    Fire: 10 11% 11.0
    Portable: 5 10% 5.0
    Navigation: 4 10% 4.0
    Durable: 9 5% 4.5
    Defense: 10 5% 5.0
    First Aid: 6 5% 3.0
    Comms: 3 5% 1.5
    Total 100% 76.1
